Cell specialisation and microscopy GapFill

The cells inside an organism perform many different roles. They must become  muscle cellsidenticalmore flexiblelargerspecialiseddifferent in order to perform these roles. Examples include  egg cellsxylem cellsnerve cellssperm cellsphloem cellsmuscle cells, which are the male reproductive cells, and root hair cells, which have a  small vacuolethick cell wallhair-like extensionflexible cell membranehydrophobic cell walllarge nucleus in order to increase the amount of absorption possible.

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