What is known as the smallest unit of life?

The smallest unit of life is known as cells. Cells are the basic building blocks of all living organisms, and they perform essential functions necessary for life. Each cell can carry out processes such as energy production, waste removal, and reproduction.

In multicellular organisms, cells can group together to form tissues, and those tissues then combine to make organs. However, while these higher levels of organization are crucial for the complexity of living organisms, they are not the fundamental units of life themselves.

An organism refers to an entire living being, which is made up of many cells, tissues, and organs working together. Thus, cells are the foundational unit from which all organisms are constructed, making them the smallest unit of life.
