## Cell Biology Mark Scheme 1. **B** (a) (i) Plant, bacterial and fungal (ii) Bacteria(1) (iii) Ribosome - (site of/involved in) protein synthesis. Mitochondria - (site of /involved in) energy or ATP production/aerobic respiration (b) Y axis scale and label, including units. Bars correctly plotted 2. **B** (a) 1. Mitochondrion: (site of) aerobic respiration or releases energy/produces ATP. 2. Cytoplasm: (site of) chemical reactions. 3. Ribosome(s): (site of) protein synthesis. 4. Cell membrane: controls or allows entry/exit of materials/substances/molecules or controls what enters/exits. Any 2 for 1 mark each (b) 100 | Mark | Description | Acceptable | Not Acceptable | |---|---|---|---| | 1 | All three required | | Extra answers negate | | 2 | Tops of bars clearly shown <br> Label copied exactly | | | | 2 | | additional correct information. | | | | | | (site of) all chemical reactions <br> specific example of a reaction <br> eg fermentation. | | | | | 'things' |
