Question | Answer |
In which cells does most photosynthesis happen? | Palisade cells |
Which gas is made during photosynthesis? | Oxygen |
What is the name of the vessel that transports water and minerals in a plant? | Xylem |
What is the function of chlorophyll? | Absorb light energy |
Through what structure do gases enter and leave a leaf? | Stoma (plural = stomata) |
What is glucose stored as in a plant? | Starch? |
Why do leaves have a large surface area? | To absorb as much light energy as possible |
What structures contain chlorophyll? | Chloroplasts |
Which cells do not contain chloroplast in a leaf? | Upper epidermis |
Which cells contain the most chloroplasts in a leaf? | Palisade cells |
What substance would you use to detect starch? | Iodine |
What gas is used during photosynthesis? | Carbon dioxide |
Whereabouts are most stomata found on a leaf? | The bottom |
How could you measure the rate of photosynthesis? | Count the number of bubbles produced by pondweed or measure the volume of oxygen produced |
What test could you carry out to prove that the gas released during photosynthesis is oxygen? | Collect the gas and place a glowing splint in it - it will relight in oxygen |
Why is it necessary to heat a leaf in ethanol before testing it for starch? | To dissolve the chlorophyll so that you can see any colour change with iodine |

What are the vessels called that transport sugars in a plant called? | Phloem |
What is the name of the cells that open and close stomata? | Guard cells |
What process occurs in plants when there is no light? | Respiration - this happens during the day as well, but the rate of photosynthesis is faster than the rate of respiration during the day |
