Plant Vacuoles The Plant Cell Oxford Academic

Plant cell vacuoles are widely diverse in form, size, content, and functional dynamics, and a single cell may contain more than one kind of vacuole Although major morphological differences were recorded by the very first microscopists, it has been commonly assumed that all vacuoles have the same origin and belong to a common group...
