Why do cells constantly take in and get rid of substances?

Answer 1

Substance need to move into and out of cells so that the cell can live and function normally For example: Carbon dioxide is a substance that moves out of a cell as it is toxic waste, if it was not moved out of the cell then the cell would die. Oxygen is a substance that moves into a cell as it is required for metabolic reactions to occur. glucose is a substance that moves into a cell as it is also required for metabolic reactions

Answer 2

Cells must get rid of waste because it contains toxins like bacteria and viruses. If these begin to multiply in the cell, it dies. After the cell is dead the viruses or bacteria infection spreads to the other cells and they die and it goes to the other cells and they die, you get the point. If the cells die then the body becomes weak and tired do to lack of energy. If most of the energy comes from glucose and mitochondria then that means when all the cells in an area die and the other cells are still dying the body, the person should probably go or the hospital.

Answer 3

Cells constantly take in substances for essential functions like energy production, building new molecules, and maintaining cellular balance. Getting rid of substances allows cells to remove waste products, maintain internal conditions, and prevent harmful build-up of substances. This balance of uptake and elimination helps cells function properly and stay healthy.

Answer 4

Because that is what they do. Your asking a question philosophers have been asking centuries on end. Why does x do y. In my opinion, it's unanswerable.
