Study Notes
Sperm Cell
- Function: Fertilizes the egg
- Adaptations:
- Possesses many mitochondria to provide energy for movement
- Contains an acrosome, an organelle holding enzymes to break down the egg's outer layer
- Has a tail for swimming towards the egg
Nerve Cell (Neuron)
- Function: Transmits electrical impulses
- Adaptations:
- Extensive dendrites, branching extensions, for connecting and receiving signals from other neurons
- Myelin sheath surrounds the cell, insulating and accelerating the electrical impulse
Muscle Cell
- Function: Contracts, enabling movement
- Adaptations:
- Contains proteins capable of sliding past each other, causing the cell to shorten or contract
- Contains many mitochondria to generate energy for muscle contraction
Root Hair Cell
- Function: Absorbs water and mineral ions from the soil
- Adaptations:
- Possesses a large surface area, maximizing the absorption of water and mineral ions
