2025 Membrane Transport

Water and minerals move from the soil into a plant by the process of

• diffusion, only

• active transport, only

• passive transport and hydrolysis

• both diffusion and active transport

After a cookie has been digested, glucose molecules enter the bloodstream by the process of

• phagocytosis

• diffusion

• ingestion

• pinocytosis

The process in which the net movement of molecules is from a region of lower concentration to a region of higher concentration is known as

• active transport

• diffusion

• osmosis

• passive transport

The diagram below represents a specialized cell located in the root of a plant. The arrows in the diagram indicate the movement of molecules of oxygen and water into the cell. Which row in the chart below correctly identifies the process responsible for the movement of each type of molecule represented in the diagram?

• 1

• 2

• 3

Base your answer to the following question on the information and diagram below and on your knowledge of biology. Starch turns blue black in the presence of a starch indicator. Dialysis tubing tied at both ends and containing starch solution is placed in a beaker of water. Yellowish brown starch indicator is then added to the water. This laboratory setup would most likely be used to demonstrate the process of

• diffusion

• active transport

• replication

• cellular respiration
