Plants are essential for all living beings. Plants provide oxygen to human beings for breathing and also grains for food. Plants are most accountable for the ecological balance. The body structure of the plants has several parts, which are known as the organs of the plant and all the organs combine to form the whole body. Organs are made up of tissues and tissues are made up of cells. Cell is the smallest part of the body structure, therefore it is known as the structural unit of the body. A cell is very small, which can’t be seen with naked eyes. It can be seen with the help of microscope only. If, we study about the cell further, then several parts are found in the cell such as nucleus, mitochondria, plasma, genes as DNA, RNA and cell walls etc. the outerenmost part of the cell is cell wall, which is composed of three layers such as outer layer, middle layer and inner layer, the outer layer is also called the primary layer. The cell wall gives the mechanical support to the cell, maintains the macro-environment of the cell, supports the movement of the substances in and out of the cell. The work presents a very realistic and perfect description of the cell and cell-parts in an interesting manner.
