Question

Quizplus · Accepted Answer

The epidermis is the outermost layer of cells in plant roots and is in direct contact with the soil. The pith is the central, typically soft and spongy, part of a plant stem, and is not in contact with the soil. The endodermis is a layer of cells that surrounds the vascular tissue in roots and acts as a barrier to regulate the movement of water and nutrients, but is not directly in contact with the soil. The pericycle is a layer of cells just inside the endodermis that gives rise to lateral roots, but is also not in direct contact with the soil. The cortex is a region of tissue in between the epidermis and the vascular tissue in plant roots, but is separated from the soil by the epidermis.
