Which tissue acts as a filter on the water absorbed by root hairs?
Answer:
The endodermis tissue acts as a filter on the water absorbed by root hairs. The endodermis is a single layer of cells that surrounds the vascular tissue in plant roots. This layer contains the Casparian strip, which is a belt-like structure made up of suberin, a waterproof substance. The Casparian strip forces water and minerals to pass through the cell membrane of endodermal cells instead of between them, acting as a selective barrier that filters out harmful substances and allows only water and essential nutrients to enter the vascular system of the plant. By regulating the entry of water and nutrients, the endodermis plays a crucial role in protecting the plant from toxins and maintaining its overall health.
