mitochondrion vs. mitochondria?

yup, this is a singular, plural thing ... it differs from our usual plurals because we take both forms from the original greek. Another example is criterion, criteria (the word criteria is often wrongly used as a singular).

in cellular respiration, hydrogen ions build up in the intremembrane space of the mitochondria

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.

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

Eukaryotes have organelles and are comparmentalized.  Prokaryotes do not have organelles and are not compartmentalized.

B) Membrane-bound organelles\nThe procariotic cells are like a water-filled baloon, they are just a cover with water and other things (of course, this is only an example), while eukaryotic cells have compartiments.\nEvery cell has DNA, that's the way information is passed from cell to cell when they reproduce.\nRibosomes are important for producing proteins, every cell has to have them, even if with time they lose them.\nCytoplasm is the 75% of every cell, it's basically water, proteins and other things.

Mitochondrial DNA (mtDNA) is DNA that is located in mitochondria. This is in contrast to most DNA of eukaryotic organisms, which is found in the nucleus. Virtually 100% of the mtDNA contribution to a conceptus is inherited from the mother.\n\nUnlike most of the cell, the function of which is defined by nuclear DNA, mitochondria have their own DNA and are assumed to have evolved separately. Human mitochondrial DNA consists of 5-10 rings of DNA and appears to carry 16,568 base pairs with 37 genes (13 proteins, 22 tRNAs and two rRNAs) which are concerned with the production of proteins involved in cellular respiration. However many proteins found in the mitochondria are encoded by nuclear DNA: some, if not most, are thought to have been originally part of the mitochondrial DNA but have since been transferred to the nucleus during evolution.\n\nThere is little change in the mtDNA from parent to offspring, unlike nuclear DNA which changes by 50% each generation. Since the mutation rate is easily measured, mtDNA is a powerful tool for tracking matrilineage, and has been used in this role for tracking many species back hundreds of generations.\n\n\nBoth chloroplast and mitochondria need variety of enzymes for different metabolic reactions.So during evolution a separate DNA is needed for it.Chloroplast is so called a cell inside a cell.

Both Prokaryotic and Eukaryotic cells might contain Ribosomes.\n\nThe organelles that Eukaryotic cells have that Prokaryotic cells do not have include a true nucleus (bound by a double membrane) and usually mitochondria.  Also in some plants, chloroplasts.

During *mitosis*, the cytoplasm of a cell and its organelles separate into two new *identical cells*?\n\nI'm not sure what else you're looking for here...

A whole cell is just that...a whole, not-cut-up, not-pieces-of-other-cells, functioning cell.\n\nThey didn't just take out the cytoplasm.  They didn't just take out mitochondira.  They took the whole cells.

Remember, mitochodria are the locale for oxidative respiration.  Glucose and fatty acids are broken down to pyruvate during glycolysis, which occurs in the cell cytoplasm and does not require oxygen. The pyruvate molecules are transported into the mitochodria where they're utlized to produce energy (ATP) via the Kreb's cycle (which occurs in the mitochodria).  This process requires oxygen, thus the term "oxidative respiration".  Lack of oxygen results in loss of ATP production, and utlimately cell death.

I would say mitochondria.

Chloroplast not only have a membrane but they have two an outer and inner. I would go with ribosomes. Everything else has a cell membrane.\nWell this is if you consider the question to ask if the organelle itself has a membrane or the cell in which the orgnelle is contained has a cell membrane.\nI took Ap Bio 2 years ago but I believe the a plant cell also has a cell membrane even though it has a cell wall. The wall keeps them from bursting when they get too much water through osmosis. An animal cell would burst.

18. D. Oxygen and energy (ATP) are products of aerobic respiration, whcih takes place in the mitocondria.\n\n19. B. The cell membrane is called a LIPID BILAYER. which has 2 layers of phospholipds. the hydrphobic tails in the center. and the 2 heads facing out side the cell and inside the cell. the inner layer would have the head facing the inside of the cell.\n\n20. A. the bactera (monerans) were one of the earliest forms of life. The had the earliest form of sexual reproduction by exchanging DNA with another bacterium through their membranes. They were also mobile (getting around from place to place). For example, some bacteria have flagela, which whip around for them to move. an getting energy from the sun... hmm. well. im not sure if bacteria can photosynthesize. but im 100% sure they can get energy from the sun INDIRECTLY through cellular respiration.

You are a mitochondria.

Mitochondria: energy plant\nER: manufacturing plant\nLysosome: garbage disposal site\nCytosol: earth\nVacuole: water plant\nChloroplast: another manufacturing plant\nCentrioles: muscles

the molecules the cell incorporates must be chemically modified to obtain Energy from them. In the first place a reaction occurs in the cytoplasm and then (for those organisms that perform respiration) inside the mitochondria some other reactions occur. The last ones are called respiration.
