casparian strip मीनिंग इन हिंदी

उदाहरण वाक्य

1. The Casparian strip forces water into the symplast at the root endodermal cells.
2. The Casparian strip, a cell wall outside the stele but within the root, prevents passive flow of water and nutrients, helping to regulate the uptake of nutrients and water.
3. If the endodermis is likened to a brick cylinder ( e . g . a smokestack ), with the bricks representing individual cells, the Casparian strips are analogous to the mortar between the bricks.
4. The cells of the endodermis typically have their primary cell walls thickened on four sides radial and transverse with suberin, a water-impermeable waxy substance which in young endodermal cells is deposited in distinctive bands called Casparian strips.
5. "' Passage cells "'are endodermal cells of older roots which have retained thin walls and Casparian strips rather than becoming suberized and waterproof like the other cells around them, to continue to allow some symplastic flow to the inside.
6. Interactions with other cations in the rhizosphere can have a significant effect on the uptake of the ion . ( Kurvits and Kirkby, 1980; The structure of root cell walls is highly permeable to water and ions, and hence ion uptake into root cells can occur anywhere from the root hairs to cells located almost in the centre of the root ( limited only by the Casparian strip ).
