Detailed explanation-1: -In all life forms, including bacteria, plants, animals, and humans, the cell was defined as the most basic structural and functional unit. Based on scientific observations over the next 150 years, scientists formulated the cell theory, which is used for all living organisms no matter how simple or complex.

Detailed explanation-2: -Cells Unit. Cells are basic units of structure and function in living things. This means that cells form the parts or an organism and carry out all of the an organism’s processes, or functions.

Detailed explanation-3: -Cells are the basic building blocks of all living things. 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.

Detailed explanation-4: -A Basic Structural Unit (BSU) is essentially a building block. In anatomy, the basic structural unit of the body is the cell. All living organisms have cells, which start as the zygote-the single cell at the beginning of life, after a spermatazoon fertilizes an oocyte.

Detailed explanation-5: -Unicellular organisms are able to live independently and carry out the fundamental tasks of life. Independent living cannot be guaranteed if a cell’s structure is incomplete. As a result, the cell is the basic structural and functional unit of all living things.
