PLANT CELLS UNLIKE ANIMAL CELLS are surrounded by a rela-tively thin but mechanically strong cell wall.

. The major difference between an animal cell and a plant cell is that plants are made up of an extra-rigid cell wall and therefore a special kind of microtubules are involved in the completion of cytokinesis. Animal cells do not have cell walls. This wall consists of a com- plex mixture of polysaccharides and other polymers that are secreted by the cell and are assembled into an organized network linked together by both covalent and noncovalent bonds. To avoid this plants build one cell wall at a time and slowly add the size and structure of all their cell wall continually.

If these cells were to lose their shape every time they went through mitosis the plant would fall over breaking many cells in the process. It makes the cell stiff -providing the cell with mechanical support - and giving it protection. When a plant is growing many cells are dividing at once even in the base of the plant.
