what is endodermis..
Answers
The cross section of a plant root is a little like the cross section of a piece of lasagna. If you've ever made lasagna, then you know that the first thing in the pan is a layer of large, flat noodles. In a plant root, that first layer would be a single layer of cells called the epidermis. Then comes a smear of ricotta cheese, some tomato sauce, and perhaps a sprinkle (or three) of mozzarella. In a plant root, that mixture of ingredients would be like the cortex, which is where the bulk of the root tissues are. Then comes another layer of large, flat noodles. That single layer of cells in the root is called the endodermis.
Answer:
The endodermis is the central and innermost layer of cortex in land plants. It is a cylinder of compact living cells, the radial walls of which are impregnated with hydrophobic substances (hydrophobic means resistant to water).
The endodermal layer in a plant, almost always in the root, regulates the water and other substances that get into the plant. The endodermis is a single layer of cells that borders the cortex of a root.
