BY Team Aakash Byju's

The circulatory system transports essential nutrients and minerals throughout the body and metabolic waste products away from the body.

In plants, the vascular tissue is involved in transportation. 

The process of transport is of two kinds.  These include: - Active Transport - Passive Transport.

Active Transport

Active transport is a type of membrane transport that consumes energy to move materials through cell membranes.

Example:  Movement of digested food materials such as amino acids and glucose across the walls of the small intestine.

Example: Movement of ions across the cell wall.

Passive Transport

Passive transport is a type of membrane transport that doesn’t require energy to move substances across the cell membranes.

Example

Transportation of oxygen and carbon dioxide through diffusion.

Example: Absorption of water by root hairs.

Differences Between Active and Passive Transport

Active transport requires cellular energy, but passive transport does not require cellular energy.

In active transport, molecules move from a low concentration gradient to a high concentration gradient.

In passive transport, molecules move from a high concentration gradient to a low concentration gradient.

Active transport is not affected by any factors, but certain factors affect passive transport.
