Question

Lateral roots develop (originate) from the following tissue:

• A. Epidermis
• B. Hypodermis
• C. Endodermis
• D. Pericycle

Hint:

Lateral roots originate from the pericycle, a tissue layer just inside the endodermis, and not from the epidermis, hypodermis, or endodermis.

Answer 1

The Correct Option is D

Lateral roots in plants develop from the pericycle. The pericycle is a layer of parenchymatous cells located just inside the endodermis of the root. These cells have the ability to divide and give rise to lateral roots. This is a critical part of root growth, allowing the plant to form a branched root system. Here's a breakdown of other options:
- Epidermis: The epidermis is the outermost layer of cells in the root and is not involved in the formation of lateral roots.
- Hypodermis: The hypodermis is present in some roots and lies beneath the epidermis, but it does not directly give rise to lateral roots.
- Endodermis: The endodermis is the innermost layer of cells surrounding the vascular tissue, and it is not directly involved in lateral root formation. Thus, the correct answer is Pericycle, where lateral roots originate.
