Transport Across the Plasma Membrane
Topic Content:
- Passive Transport
- Active TransportActive transport moves molecules and ions from a region of lower concentration to a region of higher concentration with the help of energy in the form of ATP. More
- Difference between Active and Passive Transport
Active and passive transport are the two main biological processes that play a significant role in supplying nutrients, oxygen, water and other essential molecules to the cells along with excreting toxic substances.
In active and passive transport, the goals are the same but the movements are different.
Passive Transport:
Passive transport is the movement of ions and molecules across the cell membrane without requiring energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More.
Examples of passive transport are diffusion and osmosis.
Active Transport:
This is the movement of molecules/particles through a cell membrane from a region of lower concentration to a region of higher concentration using energy from respiration.
Active transport enables plants to absorb mineral salts from the soil.

Active transport moves molecules and ions from a region of lower concentration to a region of higher concentration with the help of energy in the form of ATPAdenosine triphosphate (ATP) is an energy-carrying, found in the cells of all living things. It captures chemical energy from the breakdown of food molecules and releases it to fuel other cellular...
