Multicellular organisms develop from a single cell known as zygote by the process of mitosis. Asexual reproduction in some organisms like amoeba and vegetative reproduction in plants takes place by mitosis. This type of cell division involves many steps and it does not alter the genetic material.

27. Differences in Mitosis within Plant and Animal Cells Absent, and so spindle fibers arise from free microtubules, that assemble in one point. Present and they send out spindle fibers. Centrioles The Golgi apparatus sends vesicles filled with polysaccharides to the equator region. These vesicles fuse and form the cell plate. The cell plate develops into a cell wall by the addition of cellulose, pectin and other tough polysaccharides. Constriction of the cell membrane and the appearance of a cleavage furrow that increases in indention until the two cells separate completely. Cytokinesis Plant cell Animal cell Feature
