chloroplast of course!\nPHOTOSYNTHESIS!!

Yes, during photosynthesis, plants and trees take in carbon dioxide and release oxygen into the atmosphere.  For this reason, planting trees is encouraged !

if you're talking about plant cells, then it is for photosynthesis, the plant's way of making food. This is how it works.\n\nthe plant takes in carbon dioxide, water, and light. These are processed in the cell's chloroplasts and food is produced. The by-products of photosynthesis are sucrose (sugar) and oxygen, which is why we depend on rain forests and plants to give us a continuous supply of oxygen. In goes CO2 and out comes Oxygen!!

chloroplast contains pigments for capturing solar energy for photosynthesis.plant cells absorb light of visible spectrum that have wavelength between 400 to 700 nm. and uv radiation doesnt fall between it so plant cannot absorb this part of ligt rays. if a plant will be subjected only to uv rays then the plant will die.

living? the cell. however, some organelles encode their own genetic info (dna/rna) such as the chloroplast and mitochondria. Remarkably, chloroplasts in some algae species are able to be taken up by animals (eg: sea slugs) and still function... a testament to the complexity in organelle regulation. Phycologists r actively researching this topic. But to date, they have not yet been able to keep a chloroplast functioning outside of a biotic system. Whether this counts as alive or not, is somewhat subjective.\n\nWhether viruses r alive is another much debated question (viruses being much smaller than cells). The majority consider them not alive, cause they can't reproduce on their own. I guess if u apply that logic to the case for the chloroplast, then chloroplasts shouldn't be considered alive \n\n(the chloroplast dna can't be passed on from adult slug to baby slug... it has to be taken up [eaten] every generation)\n\nin conclusion... i'd say the cell.

Although water is required for photosynthesis the amount of water actually required is tiny, almost immeasurable even in large tree. In contrast a large tree will use hundreds of gallons of water every single day. More importantly a plant that is in the dark will die without water just as fast as a plant in full sunlight. Since photosynthesis can't occur in the dark we know that it can't be photosynthesis that  most of the water is required for.\n\nPlants need water for three main reasons, the first two are  exactly the same reasons that you need water. \n\n1) Water serves as the solvent for every chemcial reaction that makes up life. Without water life simply isn't possible because no chemical reactions assocaited with life can occur.\n\n2) Water is also essential for transporting nutrients around the plant, so minerals are taken from the soil to the leaves dissolved in water, and sugars are taken from the leaves to the roots dissolved in water.\n\n3) Plants use water to maintain their very shape. The cells themselves are held in shape by the pressure of the water inside them, like water-filled balloons. Without water the cells shrink and collapse, and we see this as the plant wilting. If the collapse goes to far t5he cells tear and that part of the plant dies.

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.

Photosynthesis uses the energy of light to make the sugar, glucose. A simple general equation for photosynthesis follows.\n\n6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O\nCarbon Dioxide + Water + Light energy → Glucose + Oxygen + Water\nPhotosynthesis occurs in two stages. In the first phase light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of glucose.\n\nIn the light-dependent reactions the pigment chlorophyll absorbs light and loses an electron that travels down an electron transport chain producing the high energy molecules NADPH and ATP. The chlorophyll molecule regains its electron by taking one from water, a process that releases oxygen gas.\n\nIn the Light-independent or dark reactions the enzyme RuBisCO captures CO2 from the atmosphere and in a complex process called the Calvin-Benson cycle releases 3-carbon sugars which are later combined to form glucose.\n\nPhotosynthesis may simply be defined as the conversion of light energy into chemical energy by living organisms. It is affected by its surroundings and the rate of photosynthesis is affected by the concentration of carbon dioxide, light intensity and the temperature.

Chloroplasts contain structures called thylakoids.\n\nThe thylakoid membrane contains the two photosystems utilized by photosynthesis. Most simply, when light strikes the reaction centers of the photosystems, electrons are released into an electron transport chain. As electrons move through the chain,  protons are pumped from the stroma of the chloroplast to the lumen (inside) of the thylakoid. Since the thylakoid membrane is impermeable to protons, a gradient is eventually built up within the thylakoid. This gradient powers ATP synthesis.

Photosynthesis is an important biochemical process in which plants, algae, and some bacteria convert the energy of sunlight to chemical energy. The chemical energy is used to drive synthetic reactions such as the formaton of sugars or the fixation of nitrogen into amino acids, the building blocks for protein synthesis. Ultimately, nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth's atmosphere. Organisms that produce energy through photosynthesis are called photoautotrophs. Plants are the most visible representatives of photoautotrophs, but it should be emphasized that bacteria and algae also contribute to the conversion of free energy into usable energy.

chloroplast are only in plant cells, they use photosynthesis to make ATP which is energy for the cell.

In the deep ocean, phytoplankton is only in a state of starvation.  They have no alternatives to carbon fixation using sunlight, unlike chemotrophic organisms, which use high concentrations of sulfur.  The closest exception is in mixotrophic organisms that can both photosynthesize and consume organic particles.

chloroplasts are a part of plants that contain chlorophyll, which is what makes the plant green.  the chlorophyll traps light energy, and with that converts CO2 into sugar and oxygen\n\nthe exact formula is actually\n\nn CO2 + 2n H2O + ATP + NADPH → (CH2O)n + n O2 + n H2O\nor\n6 CO2 + 12 H2O + ATP + NADPH → C6H12O6 + 6 O2 + 6 H2O\n\nbut you probably only need to know that chloroplasts contain chlorophyll, which help plants turn CO2(carbon dioxide), with the help of light energy, into sugars which it feeds on and O2(oxygen), which it releases.

No. In fact not every one of them. The cells which make up the roots of the plants do not because they are not designed for the process of photosynthesis.

Photosynthesis is the process by which plants convert carbon dioxide and water to glucose for energy. It takes place in the cholorplasts of the cell, which contain chlorophyll. There are two parts to photosynthesis, the light reactions, and the dark reactions, or the Calvin cycle. In the light reactions, light energy triggers electrons to form ATP and NADPH from ADP and NADP through the electron transport chain. This part also takes water and releases oxygen.\n\nIn the calvin cycle, RuBP uses carbon dioxide to create glucose, which is the energy the plant needs to function. \n\nThe products released from photosynthesis are water and oxygen.
