What is the function of the ribosomes?
Ribosomes are the site of protein synthesis. Chloroplasts absorb light energy for photosynthesis.

Which of these is a part found in plant cells but not in animal cells?
Plant cells have a cell wall but animal cells do not.

What is diffusion?
Diffusion involves the movement of particles from high concentration to low concentration.
4 of 18
Which substance moves out of respiring cells?
Carbon dioxide

How are bacterial cells different from animal cells?
Bacterial cells have a cell wall and no nucleus; animal cells have a nucleus but no cell wall.
6 of 18
How are yeast cells different from bacterial cells?
They have a nucleus
7 of 18
What do specialised cells do?
Cells may be specialised for a particular function. Their structure will allow them to carry this function out.

Which gas is needed for photosynthesis?
Carbon dioxide is needed for photosynthesis.
9 of 18
What type of energy is needed for photosynthesis to happen?
Light energy is needed for photosynthesis to happen.

The waste by-product of photosynthesis is:
Oxygen is a waste by-product of photosynthesis. Carbon dioxide is needed for photosynthesis.
11 of 18
Photosynthesis can be summarised by which word equation?
The word equation that summarises photosynthesis is: carbon dioxide + water → glucose + oxygen.

Fats, oils and starch are used by plants for storage. What they have in common is that they are:
Fats, oils and starch are insoluble. Fats and starch are solid at room temperature but oils are liquid.
