repeating the experiment
using a gas syringe to measure the volume of gas released
monitoring the temperature of the sodium hydrogen carbonate solution
using the same piece of pondweed for each light colour
Which of the following is not required for the germination of seeds?
light
oxygen
water
warmth
The diagram shows apparatus that can be used to measure the rate of photosynthesis of pondweed. What is the gas that is released by the pondweed?
carbon dioxide
hydrogen
nitrogen
oxygen
The attached diagram shows a plant cell. What is the name of this cell?
epidermis
palisade cell
root hair cell
xylem cell
The diagram shows apparatus that can be used to investigate the role of mineral ions in plant growth. What is the purpose of bubbling the air into the solution?
provide carbon dioxide for photosynthesis
provide carbon dioxide for respiration
provide oxygen for photosynthesis
provide oxygen for respiration
Roots show positive geotropism. Which of the following explains this response?
growth towards the light
growth away from the light
growth in the opposite direction to gravity
growth in the direction of gravity
