Answer 2

The Correct Sequence of Root Zones from Apex to Base

The correct sequence of root zones from the apex (tip) to the base of the root is as follows:

A. Zone of Division: This is the region at the apex of the root where cell division occurs. It is responsible for the growth and elongation of the root. The cells in this zone divide rapidly, leading to the formation of new cells that contribute to root growth [[1]].

B. Zone of Differentiation: This zone is located above the zone of division and is responsible for the differentiation of cells into specialized cell types. As the cells move away from the zone of division, they undergo specific changes in structure and function to become different cell types, such as root hairs, cortex cells, and vascular tissue [[2]].

C. Zone of Conductivity and Branching: This zone is also known as the zone of elongation. It is responsible for the transport of water and nutrients through the root. In this zone, the cells elongate and differentiate further to form the xylem and phloem, which are the conducting tissues of the root. Additionally, lateral roots may also start to develop in this zone [[3]].

D. Zone of Absorption: This zone is located near the base of the root and is responsible for the absorption of water and minerals from the soil. The root hairs, which are extensions of the epidermal cells, greatly increase the surface area available for absorption. This zone is also involved in the exchange of gases between the root and the soil [[4]].

It is important to note that the exact boundaries between these zones may vary depending on the plant species and environmental conditions. However, the general sequence of these zones remains consistent.
