Cells Explanation:

Cells are the small building blocks of all the living things. The cells are membrane enclosed and have multiple organelles that have a particular function. The cells are usually covered with a cell membrane that is partially permeable and in case of plants, has a cell wall made of cellulose too. They are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialized function. Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions. The cells are able to carry out respiration and producing energy.
