Absorption

Absorption is a process in which one substance takes in another substance. This can occur in various scientific contexts, including in plants, in the human body, and in materials science.

1. Plant Absorption

In the context of plants, absorption refers to the process by which roots take in water and nutrients from the soil. This is a crucial process for the growth and development of plants, as it allows them to obtain the essential elements they need to survive.

2. Human Body Absorption

In the human body, absorption occurs in the digestive system. When we eat food, the nutrients and water present in the food are absorbed by the small intestine and transported to the bloodstream. This allows the body to utilize the energy and nutrients from the food we consume.

3. Materials Science Absorption

In materials science, absorption refers to the process by which a substance takes in another substance. For example, a sponge absorbs water, as the water is drawn into the empty spaces within the sponge's structure.
