Movement of Substances Quiz

What are the two main processes involved in the movement of substances in plants?

• Photosynthesis and respiration

• Diffusion and active transport

• Osmosis and active transport

• Diffusion and osmosis

Which of the following is NOT a criterion for osmosis?

• Movement of water only

• Movement from high to low water potential

• Presence of a partially permeable membrane

• Movement of any substance from high to low concentration

What is a common example of a partially permeable membrane?

• Cell wall

• Visking tubing

• Nucleus

• Chloroplast

In the context of plant roots, what is the role of the root hair cell?

• To transport nutrients to the leaves

• To absorb water and mineral salts

• To store energy

• To conduct photosynthesis

How does water move through the cortex cells in plant roots?

• By capillary action

• By diffusion

• By osmosis

• By active transport

Which cell has a higher water potential, cell 1 or cell 2?

• Cell 1

• Cell 2

• Both have the same water potential

• Neither, water potential is irrelevant

What is the direction of water movement between cell 2 and cell 3?

• From cell 2 to cell 3

• Both directions equally

• No movement occurs

• From cell 3 to cell 2

What is the main function of xylem cells in the root?

• To transport water upwards to all parts of the plant

• To absorb water from the soil

• To conduct photosynthesis

• To store nutrients

Which option correctly describes the water potential comparison between cell 2 and cell 3?

• Cell 2 has a lower water potential than cell 3

• Water potential is not applicable

• Cell 2 has a higher water potential than cell 3

• Both cells have the same water potential

What is the correct answer to the examination question discussed in the video?

• Option 4

• Option 3

• Option 1

• Option 2
