Example Questions
Example Question #1 : Life Science
What controls a cell's activities?
Cell wall
Cell membrane
Nuclear membrane
Nucleus
Nucleus
To answer this question correctly, we need to know the function of the following organelles:
The cell membrane controls movement of materials in and out of the cell, and acts as a barrier between the cell and the environment.
The cell wall protects the cell, and allows water, oxygen, and carbon dioxide into and out of the cell.
The nuclear membrane controls movement in and out of the nucleus.
The nucleus controls the cell's activities.
Nucleus is the correct answer.
