GCSE Biology Quiz

What is the main function of the cell membrane?

• Provide structural support to the cell

• Regulate the movement of substances in and out of the cell

• Produce energy for the cell

• Store genetic information

What is the function of the nucleus in a cell?

• Provides structural support for the cell

• Regulates the movement of materials in and out of the cell

• Produces energy for the cell

• Control center and stores genetic material (DNA)

What is the function of the mitochondria in a cell?

• Produces energy through cellular respiration

• Regulates cell division

• Stores genetic information

• Synthesizes proteins

What is diffusion?

• The movement of particles from an area of high concentration to an area of even higher concentration.

• The movement of particles from an area of low concentration to an area of high concentration.

• The movement of particles from an area of high concentration to an area of low concentration.

• The movement of particles from an area of low concentration to an area of even lower concentration.

What is osmosis?

• The movement of water molecules from an area of high concentration to an area of low concentration through a selectively permeable membrane.

• The movement of water molecules from an area of low concentration to an area of high concentration through a selectively permeable membrane.

• The movement of water molecules from an area of low concentration to an area of low concentration through a selectively permeable membrane.

• The movement of water molecules from an area of high concentration to an area of high concentration through a selectively permeable membrane.

What factors can affect the activity of enzymes?

• Amount of water in the environment

• Temperature, pH, substrate concentration, and enzyme concentration

• Time of day

• Color of the enzyme

How does temperature affect enzyme activity?

• Temperature has no effect on enzyme activity

• Enzyme activity increases with lower temperature

• Enzyme activity decreases with higher temperature

• Temperature can either increase or decrease enzyme activity

What are the products of photosynthesis?

• Glucose and oxygen

• Carbon dioxide and water

• Nitrogen and hydrogen

• Methane and nitrogen dioxide

Where does photosynthesis take place in a plant cell?

• Mitochondria

• Cell membrane

• Vacuole

• Chloroplasts
