Absorption

Absorption is the process by which one substance takes in another substance. This can happen in various contexts, such as in the human body, in plants, and in materials.

Types of Absorption

There are several types of absorption:

Chemical Absorption: This occurs when one substance is taken in and chemically reacts with another substance. An example of this is when nutrients from food are chemically absorbed in the digestive system.
Physical Absorption: This involves the physical attraction of one substance to another. An example is the absorption of water by a sponge.
Electromagnetic Absorption: This occurs when electromagnetic radiation is absorbed by matter. For example, solar panels absorb sunlight to generate electricity.

Absorption in Plants

Plants absorb water and nutrients from the soil through their roots. This process is essential for their growth and survival. The absorbed water and nutrients are then transported to different parts of the plant for various functions.

Absorption in Materials

In materials science, absorption refers to the uptake of gases or liquids by a solid material. This can be important in various applications, such as in the absorption of pollutants by activated carbon or in the absorption of moisture by desiccants.
