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: -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: -The cell is the basic structural and functional unit of life. Cells are independent, single-celled organisms that take in nutrients, excrete wastes, detect and respond to their environment, move, breathe, grow, and reproduce.

Detailed explanation-4: -The cell is the basic structural unit of living organisms.

Detailed explanation-5: -Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That’s because all cells are surrounded by a structure called the cell membrane-which, much like the walls of a house, serves as a clear boundary between the cell’s internal and external environments.
