Question:

Which of the following plays an important role in lateral root growth in dicot root?

Options:

1. Endodermis
2. Pericycle
3. Hypodermis
4. Intrafascicular cambium

Solution:

The pericycle, which is a cell layer located just inside the endodermis in dicot roots, plays an important role in lateral root growth. The pericycle contains meristematic cells that are capable of cell division and can give rise to lateral roots. These lateral roots originate from the pericycle cells and grow outward, penetrating the outer layers of the root to ultimately emerge and develop into mature lateral roots. The endodermis, hypodermis, and intrafascicular cambium do not directly play a significant role in lateral root growth in dicot roots.
