We learned that a cell is made up of different parts that perform different functions to keep the cell alive. We learned that both plant and animal cells have a cell membrane which is a flexible covering that protects the inside of the cell from the outside environment. We learned that it is made up of proteins and phospholipids. We learned that there are many different animal cells such as nerve, skin, and blood cells. We learned about the parts of the cell that are responsible for processing, transporting, and storing molecules. The Golgi apparatus gets proteins ready for their specific jobs then packages them into tiny membrane-bound, ball-like structures called vesicles. These vesicles transport substances to other parts of the cell. One vesicle is called a lysosome which helps break down larger food molecules into smaller ones and recycle parts of the cell.
