The diagrams show four types of cell, not drawn to scale.

Which cell does not contain cytoplasm?

• 
• 
• 
• 

The diagram shows an animal cell.

What is the functional relationship between the labelled structures?

• 1 is synthesised by 4.

• 2 develops into 6.

• 3 contains products synthesised by 5.

• 4 controls the contents of 5.

What is an example of active transport?

• movement of ions up the xylem

• movement of water into root hairs

• uptake of glucose by cells of villi

• uptake of oxygen by red blood cells

Which characteristics are correct for both osmosis and diffusion?

• require a partially permeable membrane and concentration gradient

• require a partially permeable membrane and energy

• require the presence of a concentration gradient

• require energy

Potatoes of the same shape and size are placed in sucrose solutions of different concentrations. After three hours, the mass of each potato piece is measured. Which graph shows the results of this experiment?

• 
• 
• 
• 

The table shows the results of an investigation into the absorption of products of digestion in the present and absence of oxygen.

Which conclusion can be drawn from these results?

• All products of digestion are absorbed by both active transport and diffusion.

• All products of digestion are absorbed by diffusion only.

• Amino acids and glucose are absorbed by active transport only.

• Fatty acids and glycerol are absorbed by diffusion only.

The graph shows the rate of enzyme activity against temperature.

Which of the following explains the rate of enzyme activity observed at point X?

(i) Concentration of enzyme and substrate are too low

(ii) Enzymes are inactive

(iii) Enzymes do not have enough kinetic energy

(iv) Shape of substrate is not complementary to enzyme's active site

• (i) and (ii) only

• (ii) and (iii) only

• (ii) and (iv) only

• (iv) only

Which of the following is not a function of water in our body?
