| What does the theory of Endosymbiosis entail? |
|
Definition
| Ancient eukaryotes endocysed O2 utilizing cells (the early forms of mitochondria). The cell membrane enclosed the chromosome in a primitive nucleus and the mitochondria flourished in the cell. Eventually, the two have a symbiotic relationship with one another. |
