Answer 2

The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known living organisms. A cell is the smallest unit of life that can replicate independently, and cells are often called the "building blocks of life". The study of cells is called cell biology.

The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves.

Cellular processes enable organisms to meet their basic needs. the cell's life functions. Two of the most important cellular processes are diffusion and osmosis. ... As a result, the oxygen molecules pass through the cell membrane into the cytoplasm.
