Three food tests are carried out on a sample of food. The results are shown in the table.
From these results, which nutrient is in the food?
A: Reducing sugar
B: Protein
C: Starch
D: Vitamin C

D
The balanced equation for photosynthesis is shown.
What is X?
A: C6H12O6
B: C6H12O12
C: C12H6O6

The diagram shows an experiment to investigate photosynthesis.
When leaves photosynthesise, they store some carbohydrates as starch.
Potassium hydroxide absorbs carbon dioxide.
After standing in sunlight for 10 hours, leaf L contained no starch but leaf M contained a lot of starch.
What does this show?
A: A leaf cannot make starch in a sealed flask.
B: A leaf cannot make starch without carbon dioxide.
C: A leaf cannot make starch without light.
D: A leaf cannot make starch without oxygen.
The list shows some requirements of living things.
1 light
2 carbon dioxide
3 water
4 mineral ions
What do plants need to make glucose?
A: 1 and 2 only
B: 2 and 3 only
C: 3 and 4
D: 1, 2 and 3
Which structure in a plant cell makes organic nutrients?
A: cell membrane
B: cell wall
C: chloroplast
D: nucleus
A mixture of starch and saliva was set up at four different temperatures.
Each mixture was tested with iodine solution after 15 minutes and again after 30 minutes.
The results are shown in the table.
What do the results suggest?
A: The enzyme in saliva is inactive at 95 ºC.
B: The enzyme in saliva is slow to work at 35 ºC.
C: The enzyme in saliva works equally well at 15 ºC and 35 ºC.
D: The enzyme in saliva works faster at higher temperatures.
In a photosynthesis experiment, a plant is left in bright sunlight for several hours.
A leaf is then removed from the plant and tested for starch, using iodine solution.
The diagram shows the leaf from the plant that was used in the experiment.
Which diagram shows the result of the experiment?
