Question

which of the following are functions of the cell membrane? select the two correct answers. (1 point)
☐ keeps the cell rigid to support the shape of the organism
☐ protecting the cell
☐ controlling what goes in and out of the cell
☐ creates energy for the cell
☐ transporting toxic substances into the cell.

Explanation:

1. Analyze each option:

• "Keeps the cell rigid..." is a function of the cell wall (in plant cells), not the cell membrane.
• "Protecting the cell" is a function of the cell membrane as it acts as a barrier.
• "Controlling what goes in and out..." is a key function of the cell membrane (selective permeability).
• "Creates energy..." is done by mitochondria, not the cell membrane.
• "Transporting toxic substances..." is incorrect; the membrane prevents harmful substances from entering.

1. Identify the correct options based on cell membrane functions.

Answer:

B. Protecting the cell, C. Controlling what goes in and out of the cell
