GENERAL HISTOLOGY

Detailed explanation-1: -The smallest and most fundamental unit of life is a cell. The cell was found in 1665 by Robert Hooke. The cell has been described as the most fundamental structural and functional unit in all living forms, including bacteria, plants, animals, and humans.

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: -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-4: -Cells are structural units as they form the structure of the organism. Cells combine to form tissues, which further combine to form organs, and organs combine to form organic systems, which further combine to form an organism. So, the cell is the basic structural unit for all unicellular and multicellular organisms.
