Large and charged molecules cannot move directly through the cell membrane. They need the help of structure G. What is G?

• protein

• phospholipid

• nucleic acids

What are the two main macromolecules in a cell membrane?

• carbohydrates & lipids

• lipids & proteins

• proteins & carbohydrates

• nucleic acids & lipids

The function of the plasma membrane is....

• to regulate what enters and leaves the cell.
• fight bacteria and viruses that enter the cell.
• provide rigid support and protection to the cell.
• make sure each cell can move

The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell
• Certain things can enter while others cannot
• The cell manually sorts through all materials
• Only certain cells can interact with the cell.

This cell organelle helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• vacuole

• nucleus

• cell membrane
