1where is this cell is found in a flowering plant?
- AIn the male part of a flower.
- BIn the roots of the plant.
- COn the surface of a leaf.
- DIn side a leaf.
2Which TWO structures are found in plant cells but not in animal cells.
- AVacuole and cell membrane
- BChloroplasts and cell membrane
- CChloroplasts and cell wall
- DCell membrane and large vacuole.
3Where does photosynthesis occur in a rose bush?
- AA in all the parts
- BB in parts R and S only
- CC in part R only
- DD in part Q only
4Plants 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.
5Which of these shows the correct word equation for photosynthesis?
- Aglucose + carbon dioxide → water + oxygen (+ energy)
- Bglucose (+ energy) → oxygen + glycerol
- Cwater + carbon dioxide → glucose + oxygen
- Dchlorophyll + carbon dioxide → water + glycogen
6Leaves are often wide 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.
7Gases get into and out of a leaf by:
- Adiffusion.
- Babsorption.
- Cconduction.
- Dconvection.
8Look at this list of substances.
glucose, fat, cellulose, protein
Which of these substances can plants make?- Aglucose and cellulose only
- Bglucose, cellulose and fat
- Cglucose, cellulose and protein
- Dall of them
9Plants need cellulose to:
- AA store energy.
- BB repair damaged cells.
- CC make cell walls.
- DD make cell surface membranes.
10If plants do not get enough water they start to:
- AA shrink.
- BB grow towards the light.
- CC grow bigger roots.
- DD wilt.
11One important type of mineral salt for plants is:
- AA sodium chloride
- BB nitrates
- CC clay
- DD loam
12Water is carried up a plant in xylem tubes. What else do xylem tubes carry?
- AA glucose
- BB fibre
- CC mineral salts
- DD pollen
13 The atmosphere is about:
- AA 78% oxygen and 21% nitrogen.
- BB 78% nitrogen and 21% oxygen.
- CC 8% carbon dioxide and 21% oxygen.
- DD 78% oxygen and 21% carbon dioxide.
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.
17The roots have a number of functions.
Tick TWO functions of roots.- AAbsorb carbon dioxide from the air.
- BAbsorb water and mineral salts from the soil.
- CAbsorb glucose from soil.
- DHold the plant in the soil.
