Cell Wall in Plant Cells
A cell wall surrounds the plasma membrane in all plant cells. It is a porous covering of about 0.1 milli microns to 10 milli microns in size. The cell wall is chiefly composed of insoluble polysaccharides. The most common constituent is cellulose. C..
The main differences between a typical animal cell and a typical plant cell are summarized below:
Animal cell Plant cell Usually smaller in size Usually larger in size Cell wall is absent. Cellulose in any form is absent Cell wall made up of cellulose is present Cytoplasm is denser, more gra..
Structure of Cell
Cells vary in shape and size. They may be oval, spherical, rectangular, polygonal, spindle shaped, star shaped, rod-shaped or totally irregular like the nerve cell. The diversity in cells is in accordance with the role ..
