Answer to Question #12243 in Biology for robin miller

Question

•Onion root tip cells are usually used to observe cells in the process of mitosis and cytokinesis. Discuss the possible reasons for this and propose alternative cells that can be used for this purpose.

Answer 1

Root tip is a zone of active growth of plant tissue (root apical meristems
are located there), so there takes place frequent
cell division, and many
cells in this region are in different stages of mitosis. For observation of
mitosis we can also take the apical
meristem cells, which are located on the
tips of the shoots, or intercalary meristem cells from monocot plants (i.e.,
grass), which
are located at the base of nodes and leaf blades.
