Notes from AQA Book:
There are many types of animal and plant cell. As an organism matures, each cell develops into a particular type. The structure of the cell is linked to its function:
- If a cell has many mitochondria it must need a lot of energy, e.g. muscle cell, sperm cell.
- If a cell has many ribosomes it is making a lot of protein, e.g. gland cells which produce enzymes.
- Cells with tails are able to move, e.g. sperm cells.
- Receptor cells have special structures which enable them to detect stimuli, e.g. the cone cells in the eye are light sensitive.
- Neurons are specialised to carry impulses from receptors to the CNS.
- Plant cells with many chloroplaths will be photosynthesising, e.g. mesophyll cells of a leaf.
- Root hair cells increase…
