Question

How do the cells get energy?

Answer 1

Mitochondria provides energy to the cell. Without mitochondria the cell would not be able to divide, move or perform any other of their duties. [through ATP + cellular respiration]

Answer 2

thanks

Answer 3

you're welcome

Answer 4

bacteria still divide, move and perform activities.. yet they don't have any organelles (i.e. mitochondria).. the answer would depend on what type of organism it is (auto-/hetero-, chemo-/phototroph). Animals (i.e. humans) are heterotrophs, our cells use enzymes, first in the cytoplasm and then in the mitochondria, to oxidize carbon-containing compounds (e.g. glucose) to put together molecules that are "energy-rich" (because of strain and repulsion of adjacent like-charges) that can be transported elsewhere in the cell and be reused to drive energetically unfavourable processes.
