• Contractile vacuole for expelling excess water

• Digestion of food particles

• Reproduction

How do food particles enter structure Q and get digested?

• Through the beating of cilia

• By diffusion through the membrane

• By active transport

• Through photosynthesis

What process do both muscle tissue and yeast carry out according to the Diagram?

The graph shows the growth curve of an annual plant. Based on the graph, what does curve at A represent?

• Seed germination

• Decrease in the rate of photosynthesis

• Dry mass increases

• Reproduction occurs

What is the compensation point in the context of photosynthesis?

• The point where the rate of photosynthesis equals the rate of respiration.

• The point where light intensity is at its maximum.

• The point where CO2 absorption is zero.

• The point where photosynthesis stops completely.

What happens to the rate of photosynthesis if the light intensity continues to increase past the compensation point?

• The rate of photosynthesis remains constant.

• The rate of photosynthesis decreases.

• The rate of photosynthesis stops.

• The rate of photosynthesis increases indefinitely.
