A typical root possesses five parts or regions:
  1. Root cap covers the root meristem. The cells of the root cap secrete mucilage which lubricates the passage of root through the soil. Cells of root cap possess starch grains which are believed to take part in graviperception. Function cap is the protection of root meristem from soil particles.
  2. Growing point or meristematic zone produces new cells for the root cap and basal region of the root. Therefore, it is essential for the growth of the root.
  3. Cells of zone of elongation are newly formed cells which lose the power of division. They elongate rapidly which increases length of the root. The external cells possess the power of absorption of water and mineral salts from the soil.
  4. Root hair zone also represents the zone of differentiation or maturation. Most of the water absorption occurs in this region. Some of the outer cells of this zone give rise tq lateral tubular outgrowths called root hairs. The root hairs increase the exposed surface of the root for absorption.
  5. Region or zone of mature cells forms the bulk of the root without undergoing any $–$ further change. The outermost layer of this region cannot help the root in water absorption because they have thick walled or impermeable cells. Its only function is to anchor the plant firmly in the soil. Lateral roots also arise from the interior of this region.
