A student compares a palisade cell from a plant leaf receiving light with a fat-storage cell from an animal. The observations are shown in the table.
| Cell | Chloroplasts | Mitochondria |
|---|---|---|
| P, palisade cell | Many | Many |
| Q, fat-storage cell | None | Very few |
Which statement is correct?
Cell P has a greater energy demand than cell Q, and both cells photosynthesise.
Cell P has a lower energy demand than cell Q, and both cells photosynthesise.
Cell P has a lower energy demand than cell Q, and only cell P photosynthesises.
Cell P has a greater energy demand than cell Q, and only cell P photosynthesises.
