6. A plant can convert glucose into cellulose. What does the plant use cellulose for?
- To grow fruits and flowers
- To evolve so it can survive
- To strengthen the cell wall
- To make proteins which allow the plant to grow
7. What is a substrate?
- Where the breakdown occurs
- The substance being broken down
- The enzyme
8. Which method produces gametes?
9. How is a constant diffusion gradient maintained in the lungs?
- We are always breathing and blood always flows around the body
- The brain tells it to
- We are always breathing
- Blood always flows around the body
10. How does our body change to respond to exercise?
- Heart rate quickens, breathing quickens/deepens and we ache
- Heart rate slows and breathing slows/shallower
- Heart rate quickens and breathing quickens/deepens
- We ache
11. What happens to an enzyme if it's in conditions above the optimum temperature?
- There is no change
- They become denatured
- They breakdown substances faster
- They change colour
12. What else can a plant convert glucose into?
- Oils/fats
- There are no more things is can convert glucose in to
- Sugar
- Minerals
13. What is the function of bile, which is produced in the liver?
- To neutralise alkali solutions in the stomach
- To breakdown glucose
- To neutralise acid in the stomach
- To breakdown proteins
14. What happens if the temperature is too high in photosynthesis?
- The rate of photosynthesis decreases
- The rate of photosynthesis increases
15. What is the function of epithelial tissue in the body?
- To produce substances such as enzymes and hormones
- To cover parts of the body
- To bring about movement by contracting
16. How is the root hair cell adapted to fullfil it's function of absorbing minerals?
- It has a larger surface area
- It has a smaller volume
- It has a small surface area
- It has a larger volume
17. The equation for aerobic respiration is the photosynthesis equation reversed
18. What is a yeast cell bud in a yeast cell?
- It holds the nucleus; so the nucleus does not react with the acid in the cytoplasm it is stored in a separate area
- It is a genetic copy of the original cell, which separates to form another yeast cell
- It is this cell's version of a vacuole
- This is just a made up feature
19. Why do red blood cells contain no nucleus?
- There is more space for haemoglobin
- The temperature can go higher, so the haemoglobin can work better, without destroying the nucleus
- They do have a nucleus
- There is more space for water which makes the haemoglobin work better
20. How does surface area affect diffusion?
- Surface area does not affect diffusion
- The greater the surface area the faster diffusion occurs
- The greater the surface are the slower diffusion occurs
