Followings are a few reasons for the great interest in stoma: Stoma provides characters of taxonomic significance. This is due to the fact that genera and even families show great constancy for their possession of a particular stomatal complex. The study of stomatal complexes becomes very useful to understand the evolutionary relationship of plants when the classical methods of cytology [...]
