Study Notes
Cell Structure
- Cells have a cell membrane, a thin layer of protein and fat, which controls what enters and leaves the cell. It is partially permeable, allowing some substances to pass through but not others.
- Plant cells have a cell wall made mainly of cellulose. This gives strength and support to the cell. The cellulose forms fibres that criss-cross over each other. The cellulose cell wall is fully permeable, allowing large molecules to pass through it.
- Cytoplasm fills most of the cell and is mostly water (around 70%). Metabolic reactions take place in the cytoplasm.
- Vacuoles are fluid-filled spaces inside cells, surrounded by a membrane. Plant cells have large, permanent vacuoles, filled with cell sap, which help maintain shape. Animal cells have smaller vacuoles called vesicles.
- Plant cells are surrounded by a cell wall, making it hard to view the cell membrane.
- Animal cells do not have a cell wall.
Cell Types
- Plant cells are surrounded by a cell wall, while animal cells are not.
- Plant cells have large permanent vacuoles whereas animal cells have smaller vacuoles (vesicles).
