Cell Structure and Function

Jackson, Ethan, and William are studying cells in their biology class. They learned about a structure that surrounds the cell, regulates what enters and leaves the cell, and maintains homeostasis. What is this structure called?

• vacuole

• cell wall

• cell membrane

• lysosome

control the cell's activities; contains the cell's DNA

• mitochondria
• cell membrane
• nucleus
• golgi body

breaks down glucose to release ATP energy for the cell and is therefore referred to as the "powerhouse" of the cell.

The main function of chloroplasts is:

• To control what enters and leaves the cell.

• To break down glucose (food) to release energy for the cell.

• To control all activities of the cell.

• To produce glucose (food) for the cell using the sun's energy.
