The region of cell division in a root is

Explanation

In Biology, roots are an important part of plants as they help in anchoring the plant and absorbing water and nutrients from the soil. The region of cell division in a root is where new cells are produced, and this is important for the growth of the plant. The question is asking about the specific region of cell division in a root. The options given are root cap, endodermis, xylem, piliferous layer, and meristem. The correct option is meristem. Meristem is the region where new cells are constantly produced and is responsible for the growth of the root. It is found at the tip of the root and is protected by the root cap. The root cap is responsible for protecting the meristem from damage as the root grows through the soil. The endodermis is a layer of cells that surrounds the vascular tissue and is responsible for controlling the movement of water and nutrients into the plant. The xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while the piliferous layer is the region of the root where root hairs are produced to increase the surface area for absorption of water and minerals. In summary, the region of cell division in a root is the meristem, which is located at the tip of the root and is responsible for the growth of the root. It is protected by the root cap, and the other options given in the question have different functions in the root.
