- Animal building blocks
- Light microscopes can magnify up to 400 times
- Each cell is surrounded by a cell membrane (holds the cell together)
- Cell membrane controls what goes in and out of the cell.
- Organelles in cells include: Nucleus, Mitochondria and Ribosomes.
- Animals including humans are made up of millions of cells.
- Nucleus controls cell activity and is surrouded by watery cytoplasm
- Contains DNA - genetic material needed for synthesising chemicals (e.g. enzymes
- Enzymes control reactions in cytoplasm
- Electron microscopes can magnify up to 500000 times
- Mitochondria use glucose in respiration - this releases energy for the cell
- Ribosomes = tiny... they build up proteins from simpler compounds (amino acids)
- Proteins = molecules that make up enzymes
- Specialised cells are specific to one certain job and have characteristis to fit that job best!
- an example: Simple epithelial cells line inside of mouth and line cavities and tubes like blood vessels in the body
