Assimilation in Biology

Assimilation in biology refers to the process by which living organisms take in and utilize nutrients from their environment, typically to build new tissues or to store energy for future use.

Photosynthesis

During photosynthesis, plants assimilate carbon dioxide from the atmosphere and convert it into glucose, a form of stored energy. This process involves the use of sunlight, water, and chlorophyll to produce glucose and oxygen as byproducts. The glucose is then used by the plant for growth, repair, and reproduction.

Digestion

In animals, assimilation occurs during the process of digestion. When food is ingested, it is broken down into smaller molecules through mechanical and chemical processes in the digestive system. These smaller molecules, such as glucose, amino acids, and fatty acids, are then absorbed into the bloodstream and transported to cells throughout the body. The cells utilize these nutrients for various functions, such as providing energy, building proteins, and maintaining cellular structures.
