Question

What does the Casparian strip mean?

Answer 1

Casparian strips:

1. These are bands of cell wall materials that are deposited in the endodermis' transverse and radial walls.
2. Their chemical makeup differs from that of the remaining cell wall structures.
3. The cell wall is made up of lignin without suberin, but in Casparian strips, it also contains suberin and, in certain circumstances, lignin.
4. These strips serve the same purpose as tight connections found in animal epithelia.
5. It was shown to create a paracellular diffusion barrier in plant roots, allowing nutrients to enter cells. This property is referred to as the plasma membrane transport protein activity.
