Lots.
Mitochondria are found in both plant and animal Cells.
Cells that require the most energy contain the most energy generating mitochondria. The cells of the brain, the skeletal muscle and heart muscle, and the eye contain the highest number of mitochondria (as many as 10,000 per cell) while the skin cells, which do not require much energy, contain only a few hundred of them.
Few
Because muscle cells are very active. So they need a lot of energy
mitochondria flagella cilia just to name a few
Fat cells have few mitochondria because they have little need for energy. Mitochondria transform glucose into energy.
Yes, all cells need mitochondria, even if only a few. Tissues are made of cells, and muscles and organs are made of tissues. Besides, how would we move if we did not have energy in our muscles?
RPCProkariyotic cells do not have any.Some eukariyotic cells like mammalian RBC lack mitochondria
Nucleus,chloroplast,mitochondria,plasmidsthe mitochondria and chloroplast.DNA is found in the nucleus.DNA is generally located in the nucleus of a cell. There is some DNA in the mitochondria although there is significantly more DNA in the nucleus.In animal cells, DNA can be found in the nucleus and mitochondria of cells. In plant cells, DNA can be found in the nucleus, mitochondria, and chloroplast.
Because muscle cells are very active. So they need a lot of energy
Sperm cells need lots of ATP (created in mitochondria) for the reactions that cause the tail to propel to move it forward. Normal skin cells need only as much as required to keep the vital cell functions working.
Yes. A yeast cell is a eukaryotic cell and all eukaryotic cells have membrane bound organelles, that may include mitochondria. There are very few exceptions of eukaryotic cells not having mitochondria but yeast has them.
