Answer 11

Prophase
Metaphase
Anaphase
Telophase

Question 12

What happens during interphase?

Answer 12

Growing after division
Very metabolically active
Normal cell activities
DNA replicated

Question 13

What happens during prophase?

Answer 13

Chromosomes condense, shorten and become visible

Question 14

What happens during metaphase?

Answer 14

Nuclear membrane breaks down
Centromeres grabbed by centrioles
Microtubules pull chromosomes to equator

What happens during anaphase?

Answer 15

Centromeres split, pull apart and move to pole

Answer 16

New nuclear envelope forms ✉
Spindle fibres break down
Chromosomes uncoil
