B2 1.3 - Specialised Cells

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…
