Endoplasmic reticulum = 1\nRibosome(s)                 = several\nNucleus                         = 1 but has an inner Nucleolus\nlysosome                      = several\ngolgi bodies                   = I think 1  :)\nmitochondria                 = as u said "mitochondria" & not mitochondrion, so there are several of them\nvacuole                          = several (unlike the plant cell which has one big vacuole)\ncheers

there are several, one is a vacuole. It is used to store soemthing usually food within the cell

2. Cell membrane and Plasma membrane.

Yes.  The term'subcellular" would just mean it is comprised of peices smaller than a cell.\n\nThe term 'components' is simply a word for parts used for assembly.  \n\nMost of these parts are an integral part of the cell, meaning if you get rid of them you lose the cell.

Hey, this is a question I asked my professor, how funny, lol. \n\nFirst of all, it's important to note the differences between a prokaryotic and a eukaryotic cell.  \n\nCells that lack a membrane-bound nucleus are called prokaryotes (from the Greek meaning before nuclei). These cells have few internal structures that are distinguishable under a microscope. Cells in the monera kingdom such as bacteria and cyanobacteria (also known as blue-green algae) are prokaryotes. Prokaryotic cells differ significantly from eukaryotic cells. They don't have a membrane-bound nucleus and instead of having chromosomal DNA, their genetic information is in a circular loop called a plasmid. \n\nTake a look at this picture:  http://library.thinkquest.org/C004535/media/prokaryote.gif\n\nEukaryotic cells comprise all of the life kingdoms except monera. They can be easily distinguished through a membrane-bound nucleus.  Eukaryotic cells also contain many internal membrane-bound structures called organelles. These organelles such as the mitochondrion or chloroplast serve to perform metabolic functions and energy conversion. \n\nTake a look at this picture:  http://library.thinkquest.org/C004535/media/eukaryote_animal.gif\n\nFor a brief and quick response, ...a eukaryotic cell is a larger cell with distinctly more organelles within the cell.  They differ in size greatly :)

cells dont have cells but they they have organelles which are sort of like cells, which includes mitochondria, ribosomes, golgi apparatus, etc. that have various functions such as converting sugar to energy, synthesizing proteins, etc. they're sort of like minature organs if the cell was your body (hence the name organelles

An animal cell is a form of eukaryotic cell which make up many tissues in animals. The animal cell is distinct from other eukaryotes, most notably plant cells, as they lack cell walls and chloroplasts, and they have smaller vacuoles. Due to the lack of a rigid cell wall, animal cells appear to be circular (though are often deformed by surrounding cells) under microscopes - in three dimensions the cells are normally spherical.

usually at the centre. but sometimes lies in the periphal region if vacuole is too large(vacuole displaces the nucleus eg. in plant cell) \n    its size differs from cell to cell. however  its size is significantly larger than many other cell organelles like ribosome,lysosome, ER, etc but smaller than vacuole in plant cells

hes wrong (above. Prokaryotes do have organelles. THey do not have membrane bound organelles. Take for example the central vacuole of a plant. It has a membrane surrounding it, so it is not a prokaryote. Prokaryotes have ribosomes which synthesize proteins and nucleic acids to form a polypeptide chain. THey have a mitochondria for ATP etc..

Mitochondria dont' neccessarily attach to something, but they are found inside Cytoplasm.

organelle is a microscopic component of a cell...whereas a structure is refered to a cell..a whole cell and it's components

THERE ARE FOUR DIFFERENCES!!!!!!! NOT THREE. Some people say five\n\n1) Chloroplasts\n2) Central Vacuole and tonoplast (the membrane enclosing the vacuole)\n3) Cell Wall\n4) Plasmodesmata (channels through cells walls that connect cytoplasms of adjac3ent cells.)

1)  The cell is the unit of structure, physiology, and organization in living things. \n   2)  The cell retains a dual existence as a distinct entity and a building block in the   construction of organisms. \n   3)  Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).\n\nKeep this as hint and do your homework

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

Plant cells have Chloroplast... Cell Walls... and Water Vacuoles\n\nAnimals cells... of a centrioul, and food Vacoules.\n\nThose are the main differences of the organells

Hi. Are you talking about mitochondria?

Mitochondria are cell organelles in the protoplasm, responsible for providing the cell with energy. Due to its function, a mitochondrion is called the 'powerhouse of the cell'.
