Question

Order the four regions in a developing root starting with the tip of the root at the top of the list._________

Answer 1

The four regions in a developing root, starting with the tip of the root at the top of the list, are the zone of cell division, zone of elongation, zone of maturation and differentiation, and the root cap.

Step-by-step explanation:

The four regions in a developing root, starting with the tip of the root at the top of the list, are as follows:

1. Zone of cell division: This is the closest region to the root tip and is made up of actively dividing cells of the root meristem.
2. Zone of elongation: Here, newly formed cells increase in length, leading to the lengthening of the root.
3. Zone of maturation and differentiation: Beginning at the first root hair, this region is where root cells begin to differentiate into specialized cell types.
4. Root cap: The root cap is a structure exclusive to roots that protects the tip of the root and is continuously replaced due to the root pushing through soil.
