IGSCE biology, cells, specialised
| Cell | Plant or Animal | Structure | Function |
|---|---|---|---|
| Palisade cells | Plant | Full of chloroplasts, maximum surface area | trap light for photosynthesis |
| Ciliated epithelial cells | Animal | cilia | clean trachea + bronchi, keep lungs clean, waft up mucus + bacteria OR in oviducts/fallopean tubes, waft eggs to uterus |
| Sperm | Animal | vacuole containing enzymes, tail, mitochondria, stream lined | Swim to egg |
| Red blood cells | Animal | Large surface area, no nucleus, haemoglobin | carry oxygen around body |
| Muscle cell | animal | ability to contract and relax(contain actin +myasin), lots of mitochondria | movement |
| Nerve cell | animal | dendrites, long + thin, fatty myelin sheath | connects to many other cells, carry messages, speeded up electrical signal |
| Root hair cell | plant | no chloroplasts, large surface area | absorbs water and minerals from soils |
| Egg | Animal | large food store | supple zygote before impantation |
