- cell specialisation and differentiation
- cell differentiation
- how a cell changes and becomes specialised
- animal cell differentiation
- occurs at early stages of development
- only for cell repair and replacement
- plant cell differentiation
- occurs at all stages of life cycle
- stems cells are grouped together in meristems
- animal cell differentiation
- un- differentiated cells are called stem cells
- how a cell changes and becomes specialised
- cell specialisation
- specialised animal cells
- nerves
- carry electrical signals
- long branched connections
- insulating sheath
- sperm
- fertilise an egg
- streamlined
- long tail
- acrosome containing enzymes
- large number of mitochondria
- muscle
- contract to allow movement
- contains large amount of mitochondria
- long
- nerves
- specialised plant cells
- root hair cell
- absorbs water and minerals from the soil
- hair like projections to increase surface area
- phloem
- carries glucose
- translocation- living cells
- cells have end plates with holes
- flows in both directions
- xylem
- carry water and minerals
- transpiration- dead cells
- cell walls toughened by lignin
- flows in one direction
- root hair cell
- specialised animal cells
- cell differentiation
