Membranes Within Cells

Membranes Within Cells

1. Nucleus, Golgi body, chloroplast, rough and smooth ER, vacuole, vesicles, mitochondria and lysosomes

2. Control entry and exit of materials in discrete organelles

3. Isolate organelles s that specific metabolic reactions can take place within them

4. Provide an internal transport system (e.g. ER)

5. Isolate enzymes that might damage the cell (e.g. lysosomes)

6. Provide a surface on which reactions can occur

7. Act as a recognition site for human blood groups

8. Act as antigens allowing cells to recognise one another and identify self from non-self

9. Helps cells to attach to one another and so form tissues
