WebJan 10, 2024 · Active and passive transport are the two main biological process which plays an important role in supplying nutrients, water, oxygen, and other essential molecules to cells and also by removing waste products. Both active and passive transport works for the same cause, but with different movement. WebThe most direct forms of membrane transport are passive. Passive transport is a naturally occurring phenomenon and does not require the cell to exert any of its energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration.
