Question

What do you mean by active transport?

Answer 1

Active transport:

1. The movement of particles from a region of their low concentration to a region of their high concentration by spending energy is known as active transport.
2. In this type of transport, the cell has to work hard and use energy to move particles against their concentration gradient.
3. Active transport is a mode of transportation in plants, which uses stored energy to move the particles against the concentration gradient.
4. In a plant cell, it takes place in the root cells by absorbing water and minerals.
5. Active transport always leads to the accumulation of molecules are ions towards one side of the membrane.
6. This mode of transportation in plants is carried out by membrane proteins and transports the substance from the lower concentration to the higher concentration.
