Cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell.
What is a lysosome?

What is the endoplasmic reticulum?
500
Flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings.
What is a phospholipid bilayer?
500
Organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell.
