Q

What happens during anaphase?

A

Spindle fibers shorten, pulling the sister chromatids apart toward each new cell

16
Q

What happens during telophase?

A

The nucleus reappears in both cells and chromosomes decondense into chromatin

17
Q

What is the difference in cytokinesis between plant and animal cells

A

Animal cells develop a cleavage furrow that pinches in and plant cells build a wall separates the two new cells

18
Q

What is the acronym for cell division

A

I.P.MAT

19
Q

What are regulatory proteins/cydin?

A

Control cell division

20
Q

What is apoptosis and what is its function?

A

Programmed cell death and is the key to developing tissues and organs
