What is Active transport?
Advertisements
उत्तर
Active transport is the passage of a substance (salt or ion) from its lower to higher concentration through a living cell membrane using energy from the cell. Active transport is in a direction opposite to that of diffusion. Certain nutrients, such as ions of nitrates, sulphates, potassium, zinc, manganese, etc., cannot pass through the cell membrane of the root cells easily. This is because their concentration is higher inside the root cells, and it is so maintained in order to develop osmotic pressure for absorbing water.
