- 1What's differentiation?When a cell changes to become specialized for it's job
- 2When does differentiation occur in most animal cells?During development, as the ability to differentiate is lost once cells become specialized

- 6How are sperm cells specialized?Long tail and streamlined head to get to the egg
Lots of mitochondria to provide needed energy
Enzymes in head to to digest the egg's membrane - 7How are nerve cells specialized?Long to cover more distance
Branched connections so they can connect to other nerve cells and form a network - 8How are muscle cells specialized?Long - space to contract
Lots of mitochondria - for energy needed - 9How are root hair cells specialized?Large surface area - increased water and mineral intake
- 10How are phloem and xylem cells specialized?Long and joined end to end - forms tubes
Hollow / small subcellular structures - stuff flows through them
