Cell specialisation and microscopy GapFill

The cells inside an organism perform many different roles. They must become  more flexiblespecialiseddifferentmuscle cells in order to perform these roles. Examples include  sperm cellsegg cellsmuscle cellsxylem cells, which are the male reproductive cells, and root hair cells, which have a  small vacuolehydrophobic cell wallthick cell wallhair-like extension in order to increase the amount of absorption possible. The cells that pass signals from one area to another in an animal are called  stem cellscommunication cellsnerve cellsphloem cells and have a  flexiblelongtoughshort axon that allows the cells to extend great distances.

Plant and animal cells are different in terms of when they are able to make specialised cells.
