Question

Write correct terms/options for the movement of particles:

Suspended particles from lower to higher concentrations.

Answer 1

Transportation in Living Organisms

1. Transportation is a necessary, natural, and physiological activity in all higher organisms such as plants, animals, and humans.
2. This process is critical to life's survival since it continually transports various vital elements to and from all body parts, including cells, tissues, and organs.
3. Diffusion, facilitated diffusion, active transport, and passive transport are the four main types of transportation in a living body.

Active Transport

1. Active transport is described as the movement of molecules from a lower concentration region to a higher concentration region against a gradient or an obstruction using external energy.
2. A protein pump uses stored energy in the form of ATP to move molecules during the active transport process.
3. Some examples of active transport include the absorption of glucose in the human gut and the uptake of minerals or ions into plant root hair cells.

The movement of suspended particles from a lower to higher concentration is known as active transport.
