Question

Differentiate between the following pairs on the basis of what is mentioned in brackets:

Active Transport and Diffusion [significance in plants].

Answer 1

Active transport:

1. Active transport is the process of mineral ion uptake against a concentration gradient using energy from the cell.
2. It occurs only in one direction.

Diffusion:

1. The process of molecules moving from a region of higher concentration to a region of lower concentration is known as diffusion.
2. Diffusion is an important part of photosynthesis because it allows the carbon dioxide from the stomata to diffuse into the leaves and then into the cells.

Active transport	Diffusion
Plants absorb minerals from the soil by this method, even if they are present in higher quantities inside the cells.	Water moves from one plant cell to the next through this process.
