Question 1:

Which of the following is a function of the cell membrane?

Explanation: The cell membrane serves multiple functions, including protection of the cell, regulation of material entry and exit, and cell communication. Therefore, option D is correct.

Question 2:

Which type of transport requires energy input from the cell?

Explanation: Active transport requires energy input from the cell to move substances against their concentration gradient. Therefore, option C is correct.

Question 3:

Which of the following is an example of passive transport?

Explanation: Diffusion is a form of passive transport where molecules move from an area of higher concentration to an area of lower concentration without the need for energy input. Therefore, option C is correct.

Question 4:

Which transport process involves the engulfment of particles by the cell membrane?

Explanation: Endocytosis is a process by which the cell membrane engulfs particles or substances from the extracellular environment. Therefore, option A is correct.

Question 5:

Which transport process releases substances from the cell using vesicles?

Explanation: Exocytosis is the process of releasing substances from the cell using vesicles that fuse with the cell membrane. Therefore, option A is correct.
