Which of the following is the middle layer in the root apical meristem that gives rise to the cortex?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1)- Periblem
The middle layer in the root apical meristem that gives rise to the cortex is periblem.
Here's a breakdown of the root apical meristem layers:
- Dermatogen: The outermost layer, responsible for the root cap (protects the tip)
- Periblem: The middle layer, differentiates into the cortex (provides support and storage)
- Plerome: The innermost layer, develops into the vascular tissue (transports water and nutrients)
Calyptrogen is sometimes referred to as a separate layer in some classifications, but it's a sub-layer of the dermatogen specifically responsible for root cap formation.
