The Importance of Cell Differentiation Flashcards

All 6 cards in this deck

What is differentiation?: The process by which an unspecialised cell becomes specialised for a particular function.
Also accepted: specialisation.
Why is cell differentiation important in the development of an organism?: It produces specialised cells, each with a structure suited to a particular function, which form the tissues and organs the organism needs.
What happens to a cell's structure when it differentiates?: It changes shape and develops different subcellular structures suited to its function.
e.g. a root hair cell grows a long extension to absorb water.
True or false? Cell differentiation increases the number of cells in an organism.: False. Cell division increases cell number; differentiation changes unspecialised cells into specialised ones.
True or false? In animal growth, cells divide first and then differentiate.: True. Cell division produces new cells, which then become specialised.
What is formed when a group of similar specialised cells work together?: A tissue.
