The chloroplast -- it's called photosynthesis.
1170834
Photosynthesis occurs in chloroplast in all eukaryotic green cells eg:All higher plants and in chromatophores in prokaryotic green cells suchas Nostoc,Anabaena etc.. \nDuring photosynthesis radiant solar energy is converted into chemical energy.\nUsing light energy carbondioxide is reduced into carbohydrates. The source of hydrogens for the reduction of carbon dioxide is from water. same light energy is useful in splitting water molecules, as a result oxygen comes into the atomosphere & hydrogen for reduction of corbondioxide

That question would require an essay to answer fully.\n\nSome protists, such as kelp, are get energy by photosynthesis.\n\nSome protists, such as Amoeba, get energy by endocytosis.\n\nSome protists, such as Entomoeba, gete energy by direst absorption.\n\nAnd so on and so forth. There are hundreds of thousands of species of protists and they use every conceivable method of obtaining energy.

In cell biology, a mitochondrion (from Greek mitos thread + khondrion granule) is an organelle found in most eukaryotic cells, including those of plants, animals, fungi, and protists. A few cells, such as the trypanosome protozoan, have a single large mitochondrion, but usually a cell has hundreds or thousands of mitochondria. The exact number of mitochondria depends on the cell's level of metabolic activity: more activity means more mitochondria. Mitochondria can occupy up to 25% of the cell's cytosol.\n\nMitochondria are sometimes described as "cellular power plants", because their primary function is to convert organic materials into energy in the form of ATP via the process of oxidative phosphorylation.

What's your question about it?\n\nThis is the mechanism by which ATP is produced in bacteria, mitochondria and chlorplasts.  Energy for the formation of ATP (by the enzyme ATP synthase) is provided by a proton charge and concentration gradient across a membrane (inner mitochondrial membrane or thylakoid membrane, or plasma membrane in bacteria).  What else would you like to know?

The answer is probably "c".\n\nThere are two types of photosynthetic cells in C4 plants... bundle-sheath and mesophyll. The mesophyll cells are between the bundle-sheath cells and the leaf surface, and are rather loosely arranged.\n\nI think the answers are slightly weird, because the Calvin cycle is only occurring in the chloroplasts of the bundle sheath. The reason that C4 plants are more efficient is that the mesophyll cells incorporate carbon dioxide into organic compounds, effectively pumping carbon dioxide into the bundle sheath, which keeps the carbon dioxide concentration in the bundle-sheath cells high enough for the Calvin cycle to function properly.\n\nIn any event, the answer is definitely not A, B, or D.

Photosynthesis is the process that all green plants use to convert water and nutrients with the aid of chlorophyll\nand energy from sunlight into food(glucose).\nrespiration is only part of the process that allows all living things(including plants) to produce energy via andosine triphosphate breakdown to grow, move and reproduce. respiration is the process of transporting air(oxygen)into the body to allow breakdown of food into energy and waste products\ngirl, you need more confidence in yourself.\ni don't have a major in biology, infact i only have what you call high school education.\nsome people may want to fool you.\nGod bless,\ngabe\nps, algae is a plant, it may be single celled , but still a plant.

Here's what they have in common:\n1. Cell membrane is present.\n2. Vacuoles are present.\n3. Both are living cells.\n4. Mitochondria is present.\n5. Both are eukaryotic cells. \n6. Nucleus, nuclear membrane and chromatin fibers are present.\n7. Both can reproduce through mitosis. (Advanced animal cells reproduce through meiosis)\n\nPS : Don't take note of those who talk of the absence of mitochondria in plants. It's present. Only chloroplast is absent in animal cell.

Lol. I did this for homework once. Ok ok ok. I'll help yah out since i'm a pretty cool chickk. I'm not going to spend all day rewording these for you so you're going to have to do that part yourself, k?♥\n\nMitochondria: \nMitochondria are the cells' power sources. They are distinct organelles with two membranes. Usually they are rod-shaped, however they can be round. The outer membrane limits the organelle. The inner membrane is thrown into folds or shelves that project inward. These are called "cristae mitochondriales".\n\nChloroplast:\nA green structure, or organelle, contained in the cytoplasm of plant cells. Chloroplasts are reponsible for the green color of almost all plants and are lacking only in plants that do not make their own food, such as fungi and nongreen parasitic or saprophytic higher plants. The chloroplast is generally flattened and lens-shaped and consists of a body, or stroma, in which are embedded from a few to as many as 50 submicroscopic bodies–the grana–made up of stacked, disklike plates. The chloroplast contains chlorophyll pigments, as well as yellow and orange carotenoid pigments. Chloroplasts are thus the central site of the photosynthetic process in plants. The chloroplasts of algae are simpler than those of higher plants and may contain special, often conspicuous, starch-accumulating structures called pyrenoids.\n\nGolgi Apparatus:\nThe Golgi apparatus (also called a Golgi body, Golgi complex, or dictyosome) is an organelle found in most eukaryotic cells, including those of plants, animals, and fungi. The name comes from Italian anatomist Camillo Golgi, who identified it in 1898. The primary function of the Golgi apparatus is to process proteins targeted to the plasma membrane, lysosomes or endosomes, and those that will be formed from the cell, and sort them within vesicles. Thus, it functions as a central delivery system for the cell. It is part of the endomembrane system.\n\nRough&Smooth Endoplasmic Reticulum:\nThe endoplasmic reticulum or ER (endoplasmic means "within the cytoplasm," reticulum means "little net") is an organelle found in all eukaryotic cells. It is part of the endomembrane system. The ER modifies proteins, makes macromolecules, and transfers substances throughout the cell. Prokaryotic organisms do not have membranous organelles and thus do not have an ER. The basic structure and composition of the ER is similar to the plasma membrane, although it is actually an extension of the nuclear membrane. The ER is the site of the translation, folding, and transport of proteins that are to become part of the cell membrane (e.g., transmembrane receptors and other integral membrane proteins) as well as proteins that are to be secreted or "exocytosed" from the cell (e.g., digestive enzymes).\n\n*The ER consists of an extensive membrane network of tubes and cisternae (sac-like structures) held together by the cytoskeleton.\n\nRough ER:\nThe rough ER, also called granular ER or ergastoplasm (acronyms rER or gER) manufactures and transports proteins destined for membranes and secretion. It is called "rough" because ribosomes present on the cytosolic side of the membrane give it a rough appearance.\n\nSmooth ER:\nThe smooth ER (also known as agranular ER or aER) has functions in several metabolic processes, including synthesis of lipids, metabolism of carbohydrates, and detoxification of drugs and poisons. Enzymes of the smooth ER are important to the synthesis of lipids, including phospholipids and steroids. Among the steroids produced by smooth ER are the sex hormones of vertebrates and the various steroid hormones secreted by the adrenal glands. The cells that actually synthesize and secrete these hormones - in the testes and ovaries, for example - are rich in the smooth ER.\n\nRibosomes:\nRibosomes are responsible for assembling the proteins of the cell. Ribosomal subunits are synthesized by the nucleolus. Depend

Cytoplasmic streaming is the flowing of cytoplasm in eukaryotic cells. This occurs in both plant and animal cells. It creates cytoplasmic reorganization during cell reproduction. In unicellular organisms such as amoeba, it provides the mechanism for cell locomotion. It aids in the delivery of nutrients, metabolites, and genetic information to all parts of larger plant cells. It vigorously "stirs" these components about the cytoplasm. As membrane-bound organelles crawl along the inner cell wall they set the cytoplasm into motion. This streaming allows other organelles and nutrients to flow in the stream created. This allows the components of the cell to flow around the cell and balance the amount of nutrients that exist in different parts of the cell providing nutrients and enzymes, as well as a means of motion for unicellular eukaryotes, like amoeba. Actin filaments play a role in streaming.\nCytoplasmic streaming is a process found in many plant cells that moves large quantities of cytoplasm (including organelles) around the cell. This phenomenon is most pronounced in larger, highly vacuolated cells and is generally assumed to allow for efficient mixing and distribution of solutes. Cytoplasmic streaming has been studied extensively in internodal cells of characean algae (Kuroda, 1990; Shimmen and Yokota, 1994). It usually is driven by the acto-myosin system, although instances of microtubule-based organelle movement have been described (e.g. Mizukami and Wada, 1981; Mineyuki and Furuya, 1986). Studies of streaming events in the past have relied on visualization of moving organelles with phase-contrast or Nomarski microscopy. The nature of the organelles was therefore mostly unknown. The participation of Golgi vesicles in cytoplasmic streaming was inferred based only on the effects of inhibitor studies (e.g. Mollenhauer and Morré, 1976).It also has been proposed that entire Golgi stacks might participate in the streaming motion (Staehelin and Moore, 1995). This postulated movement of Golgi stacks has recently been demonstrated in tobacco (Nicotiana clevelandii) leaf epidermal cells by means of green fluorescent protein (GFP) transiently expressed in the Golgi as a fusion with the targeting domain of mammalian sialyltransferase (Boevink et al., 1998). Golgi stack movement may also provide the mechanism responsible for their dispersed distribution throughout the cytoplasm. At the same time, this movement imposes additional constraints on the possible mechanisms for transport to and from the Golgi.

Organelles\nMain article: Organelle \nThe human body contains many different organs, such as the heart, lung, and kidney, with each organ performing a different function. Cells also have a set of "little organs," called organelles, that are adapted and/or specialized for carrying out one or more vital functions. Membrane-bound organelles are found only in eukaryotes.\n\nCell nucleus (a cell's information center)  \nThe cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes, and is the place where almost all DNA replication and RNA synthesis occur. The nucleus is spheroid in shape and separated from the cytoplasm by a double membrane called the nuclear envelope. The nuclear envelope isolates and protects a cell's DNA from various molecules that could accidentally damage its structure or interfere with its processing. During processing, DNA is transcribed, or copied into a special RNA, called mRNA. This mRNA is then transported out of the nucleus, where it is translated into a specific protein molecule. In prokaryotes, DNA processing takes place in the cytoplasm. \nRibosomes (the protein production machine)  \nRibosomes are found in both prokaryotes and eukaryotes. The ribosome is a large complex composed of many molecules, including RNAs and proteins, and is responsible for processing the genetic instructions carried by an mRNA. The process of converting an mRNA's genetic code into the exact sequence of amino acids that make up a protein is called translation. Protein synthesis is extremely important to all cells, and therefore a large number of ribosomes — sometimes hundreds or even thousands — can be found throughout a cell. \nMitochondria and Chloroplasts (the power generators)  \nMitochondria are self-replicating organelles that occur in various numbers, shapes, and sizes in the cytoplasm of all eukaryotic cells. As mitochondria contain their own genome that is separate and distinct from the nuclear genome of a cell, they play a critical role in generating energy in the eukaryotic cell, a process involving a number of complex metabolic pathways. Chloroplasts are larger than mitochondria, and convert solar energy into a chemical energy ("food") via photosynthesis. Like mitochondria, chloroplasts have their own genome. Chloroplasts are found only in photosynthetic eukaryotes, like plants and algae. There is a number of plant organelles that are modified chloroplasts; they are broadly called plastids, and are often involved in storage. \nEndoplasmic reticulum and Golgi apparatus (macromolecule managers)  \nThe endoplasmic reticulum (ER) is the transport network for molecules targeted for certain modifications and specific destinations, as compared to molecules that will float freely in the cytoplasm. The ER has two forms: the rough ER, which has ribosomes on its surface, and the smooth ER, which lacks them. Translation of the mRNA for those proteins that will either stay in the ER or be exported from the cell occurs at the ribosomes attached to the rough ER. The smooth ER is important in lipid synthesis, detoxification and as a calcium reservoir. The Golgi apparatus, sometimes called a Golgi body or Golgi complex is the central delivery system for the cell and is a site for protein processing, packaging, and transport. Both organelles consist largely of heavily-folded membranes. \nLysosomes and Peroxisomes (the cellular digestive system)  \nLysosomes and peroxisomes are often referred to as the garbage disposal system of a cell. Both organelles are somewhat spherical, bound by a single membrane, and rich in digestive enzymes, naturally-occurring proteins that speed up biochemical processes. For example, lysosomes can contain more than three dozen enzymes for degrading proteins, nucleic acids, and certain sugars called polysaccharides. Here we can see the importance behind compartmentalization of the eukaryotic cell. The cell could not

Short answer yes it is true\n\nlong answer\n\nhttp://en.wikipedia.org/wiki/Calvin_cycle\n\nre previous answer\n\nChloroplasts are flat discs usually 2-10 micrometer in diameter and 1 micrometer thick. The chloroplast has a two membrane envelope termed the Inner & Outer membrane respectively. Between these two layers is the intermembrane space.\n\nThe fluid within the chloroplast is called the stroma, corresponding to the cytoplasm of the bacterium, and contains tiny circular DNA and ribosomes, though most of their proteins are encoded by genes contained in the cell nucleus, with the protein products transported to the chloroplast.\n\nWithin the stroma are stacks of thylakoids, the sub-organelles where photosynthesis actually takes place. A stack of thylakoids is called a granum (plural: grana). A thylakoid looks like a flattened disk, and inside is an empty area called the thylakoid space or lumen. The photosynthesis reaction takes place on the membrane of the thylakoid, and, as is also the case with mitochondria, involves the coupling of cross-membrane fluxes with biosynthesis.

Light reactions take place on the thykaloid membranes of the chloroplast. Light reaction requires light and water, and produces ATP and Oxygen. Dark reactions take place in the stroma (fluid that fills the chloroplast). It uses the ATP produced in light reactions to make glucose.
