Active transport is important because it allows the cell to move substances against the concentration gradient. Active transport allows the cells to maintain the appropriate balance of substances regardless to the concentration of that substance outside the cell.

Answer 2

Question:

Explain the importance of active transport in plants

Answer:

Active transport is the movement of molecules from an area of lower concentration to the area of higher concentration. This movement against the concentration gradient requires energy in the form of ions.

Explanation:-

In this process, carrier proteins of cell membrane use energy to move the molecules against the concentration gradient. For example, the membranes of nerve cells have carrier proteins in the form of "sodium-potassium pump". In a resting (not conducting nerve impulse) nerve cell, this pump spends energy (ATP) to maintain higher concentrations of K and lower concentrations of Na inside the cell. For this purpose, the pump actively moves Na to the outside of the cell where they are already in higher concentration.

Similarly this pump moves K from outside to inside the cell where they are in higher concentration.
