Here's why:
* Diffusion: The movement of molecules from an area of high concentration to an area of low concentration. This is how cells obtain essential nutrients like oxygen and get rid of waste products like carbon dioxide.
* Osmosis: The movement of water across a selectively permeable membrane from an area of high water concentration to an area of low water concentration. This is crucial for maintaining the proper water balance within cells and tissues.
Therefore, diffusion and osmosis are vital processes that allow cells to take in necessary substances and eliminate waste, which is essential for maintaining life.
