Q

What is cytokinesis?

A

1 cell going through mitosis to split into 2 cells

17
Q

How is cytokinesis different in plant and animal cells?

A

In plant cells they have a cell wall, so they connect by a cell plate

18
Q

What happens if G0 phase does not work correctly?

A

It will make too many cells which can cause cancerous cells

19
Q

What does disruptions in the cell cause?
