2) Food: Cells need a way to obtain and digest food.
3) Waste: Cells need a way to get rid of waste.
4) Energy: Cells need a way to obtain and use energy.

1. Control: Cells need a way to control and direct their own processes and functions.
2. Food: Cells need a way to obtain and digest food.
3. Waste: Cells need a way to get rid of waste.
4. Energy: Cells need a way to obtain and use energy. This is done through a process called cellular respiration. Cellular respiration is the process by which cells break down glucose to produce ATP. ATP is the energy currency of the cell and is used to power all of the cell's activities.
5. Transport: Cells need a way to transport substances within the cell.
6. Reproduction: Cells need to make more of themselves. This is done through a process called cell division. Cell division is the process by which a single cell divides into two identical daughter cells.
