GENERAL HISTOLOGY

Detailed explanation-1: -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-2: -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.

Detailed explanation-3: -The invention of the microscope led to the discovery of the cell by Hooke. While looking at cork, Hooke observed box-shaped structures, which he called “cells” as they reminded him of the cells, or rooms, in monasteries. This discovery led to the development of the classical cell theory.
