passive transport
|
|
|
active transport

|
diffusion
|

|
facilitated difussion

Explanation:
Detailed explanation-1: -Active transport is the transport of molecules that require the use of energy, in the form of an energy-storing chemical called ATP (adenosine triphosphate) to help them cross the cell membrane.
Detailed explanation-2: -Active transport uses energy to transport molecules across the plasma membrane. This uses energy from ATP.
Detailed explanation-3: -Solute particles can traverse the membrane via three mechanisms: passive, facilitated, and active transport. Some of these transport mechanisms require the input of energy and use of a transmembrane protein, whereas other mechanisms do not incorporate secondary molecules.
