Cell specialisation and microscopy GapFill

The cells inside an organism perform many different roles. They must become  largermore flexibledifferentmuscle cellsidenticalspecialised in order to perform these roles. Examples include  egg cellssperm cellsxylem cellsmuscle cellsphloem cellsnerve cells, which are the male reproductive cells, and root hair cells, which have a  large nucleushair-like extensionsmall vacuolehydrophobic cell wallflexible cell membranethick cell wall 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.
