Dictionary > Apoplasty


(botany) Apoplastic pathway; i.e. the pathway formed by apoplast and is involved in the transport of water and ions across a tissue or an organ
(protozoology) The condition characterized by the formation of apoplast due to rapid cell division
In botany, apoplasty pertains to the pathway formed via the apoplast. The apoplast refers to the space formed in between the cells. It is comprised of the cell walls and the intercellular materials, which are all nonliving components. The apoplastic pathway aids in the transport of materials across a tissue or organ. In roots, the Casparian strip, a band of cell wall material on the radial and transverse walls of the endodermis, interrupts the flow of materials (e.g. water and solutes) via the apoplastic pathway. As a result, solutes flow via the symplastic pathway, which is important so that there would be a selective passage of solutes, particularly when some solutes are potentially harmful to the plant. Nevertheless, the apoplstic pathway is a faster route than the symplastic pathway.
In protozoology, the apoplasty is a condition wherein some plastids lack pigments due to the rate of cell division outpaces the division of plastids. As a result, there are individual protozoans with plastids lacking colour in a group that is generally coloured.
