  • Specialised Cells
    • If a cell has a mitochondria, it must need a lot of energy, e.g. muscle/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 cell
    • 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 the receptors to the CNS
    • Plant cells with many chloroplasts will be photosynthesising, e.g. mesophyll cells of a leaf
    • Root hair cells increase the surface area of the root so that it can absorb water and mineral ions efficiently
