Answer:
Option- (D):All of these choices pose a problem
Step-by-step explanation:
- If we discover a gene that regulates both the amount of root hairs and where root hairs grow on a root tip. Since the surface area provided by root hairs is so critical to their uptake of water and nutrients, expanding their growth area seems a great advantage.
- So, in that case we would face the following issues during the process which we undertake.
- Growth of root hairs in the zone of cell division would interfere with root cell proliferation.
- Growth of root hairs in the root cap would cause them to be shredded off since this area takes substantial abrasion.
- Growth of root hairs in the zone of elongation would cause them to be shredded off as they anchored in soil and the root lengthened.
