what cell cycle structure would be found in animal cells but not in plants?

Question

A. sister chromatids
B. metaphase plate
C. contractile ring
D. mitotic spindle

Answer 1

I'm pretty sure it's the contractile ring. Remember that animal cells have cell membranes that merely need to be pinched off to create two daughter cells at the end of mitosis, whereas plant cells have cell walls. The cell walls are rigid, so that a cell plate merely develops between the two new cells for separation.

Answer 2

C. contractile ring

Answer 3

I have no idea. It's been over seven years since I took bio.
