1Where does photosynthesis occur in a rose bush?
- AA In the leaves
- BB In the roots
- CC In the flowers
- DD In the seeds
2 Plants often turn some of the food they make into another substance for storage.
The name of this substance is:- AA glucose
- BB starch
- CC fibre
- DD pasta
3Which of these shows the correct word equation for photosynthesis?
- AA glucose + carbon dioxide → water + oxygen (+ energy)
- BB glucose (+ energy) → oxygen + glycerol
- CC water + carbon dioxide → glucose + oxygen
- DD chlorophyll + carbon dioxide → water + glycogen
4 Aerobic respiration is a process which:
- AA stores chemical energy in food.
- BB makes food for plants living under water.
- CC does not happen in plants but only in humans when they exercise hard.
- DD releases energy from food.
5Leaves are often wide (broad) so that they can:
- AA absorb as much sunlight as possible.
- BB catch as much rain as possible
- CC provide shelter for animals living under them.
- DD float to the ground when they drop in autumn.
6Gases get into and out of a leaf by:
- AA diffusion
- BB absorption
- CC conduction
- DD convection
7Look at this list of substances: glucose, fat, cellulose, protein.
Which of these substances can plants make?- AA glucose and cellulose only
- BB glucose, cellulose and fat only
- CC glucose, cellulose and protein only
- DD all of them
8Plants need cellulose to:
- AA store energy.
- BB repair damaged cells.
- CC make cell walls.
- DD make cell surface membranes.
9The picture shows a cell from a root. What is it called?
- AA xylem cell
- BB root cortex cell
- CC root hair cell
- DD root palisade cell
10If plants do not get enough water they start to:
- AA shrink.
- BB grow towards the light.
- CC grow bigger roots.
- DD wilt.
11 One important type of mineral salt for plants is:
- AA nitrate
- BB sodium chloride
- CC loam
- DD clay
12Water is carried up a plant in xylem tubes. What else do xylem tubes carry?
- AA glucose
- BB fibre
- CC mineral salts
- DD pollen
13The atmosphere is about:
- AA 81% oxygen and 21% nitrogen.
- BB 78% nitrogen and 21% oxygen.
- CC 81% carbon dioxide and 21% oxygen.
- DD 78% carbon dioxide and 21% oxygen
14Look at these chemical processes. photosynthesis respiration burning fuels
Which of these processes add carbon dioxide to the air?- AA respiration and burning
- BB respiration only
- CC photosynthesis and respiration
- DD burning only
15Plants are important in keeping the atmosphere in balance because:
- AA they use up oxygen.
- BB they use up carbon dioxide.
- CC they provide food for animals and humans.
- DD they use water.
16Which of these would NOT be a disadvantage of cutting down forests?
- AA Logging companies could make more profits.
- BB There would be fewer trees to keep the atmosphere in balance.
- CC Some species might become extinct.
- DD Floods might wash away the soil.
17Where does photosynthesis occur in a rose bush?
- AA In all the parts
- BB In leaves and flowers only
- CC In the leaves only.
- DD In the stem only.
