- Specialised Animal Cells
- Sperm Cell
- Role
- Gamete contains half the genetic material, the sperm must deliver this to the ovum.
- Specialisation
- Acrosome contains enzymes to get through jelly layer of egg cell.
- Role
- Ovum
- Role
- gamete contains half genetic materiel, needed to nurture cell division and fertilisation.
- Specialisation
- Cytoplasm contains nutrients to support growth and division. Cell membrane rapidly changes on fertilisation to stop second sperm.
- Role
- Ciliated Epithelial cell
- Role
- Move muscles or liquid past cells
- Specialistaion
- Hairlike projections to move lots of Mitochondria
- Found in lining of airways and Fallopian tubes
- Role
- Muscle Cell
- Role
- Contract to shorten Muscle and generate movement.
- Specialisation
- Long, thin and aligned in same direction
- In skeletal muscles many cells merge together so there is many nuclei
- Role
- Neurone
- Role
- Pass on electrical impulses and use chemicals to pass on signals to adjacent neurones.
- Specialisation
- Axons are long and thin to send electrical impulses
- Dendrites to receive signals
- Nerve Endings are one part of the synapse to release chemicals
- Role
- Sperm Cell
