The nuclear membrane starts to dissolve. is...
Prophase
This is the process where cells divide uncontrollably and form tumours.
Cancer
These are the four main types of animal tissue.

Asexual reproduction
The cytoplasm and organelles divide equally.
The cell splits into two genetically identical daughter cells.
