Anmerkungen:
- All living organisms carry out these seven life processes:
Movement, Respiration, Sensitivity, Nutrition, Excretion, Reproduction, and Growth.
- Animal and Plant cells
Anmerkungen:
- Animal and plant cells share:
A cell surface membrane, cytoplasm, and a nucleus.
- Plant cells don't share these with animal cells:
A cellulose cell wall, a large vacuole, chloroplasts, and the starch storage granules.
- Animal cells don't have anything that they share with plant cells
- Specialised cells
Anmerkungen:
- CILIATED EPITHELIAL CELLS can trap dust and microbes and move them out of the breathing system.
- MUSCLE CELLS can use energy to get shorter - when they do this they can move bones.
- SPERM CELLS can swim to an EGG CELL so that fertilisation can take place.
- NERVE CELLS are long and thin. They carry messages from one part of the brain to another. This helps to co-ordinate all the different activities around the body.
- PALISADE CELLS in the leaf contain many chloroplasts and can carry out photosynthesis very efficiently.
- ROOT HAIR CELLS can absorb water and minerals from the soil.
