- Prothorax
- Mesothorax
- Metathorax
- Prothorax and Mesothorax
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Tegmina in cockroaches are the leathery forewings that provide protection to the hind wings and are involved in gliding. These wings are derived from the mesothorax. The thorax of a cockroach is divided into three segments: prothorax, mesothorax, and metathorax. Each of these segments supports a pair of legs, and the mesothorax additionally supports the forewings, known as tegmina, offering a protective covering.
| Thoracic Segment | Structure |
|---|---|
| Prothorax | First pair of legs |
| Mesothorax | Tegmina (forewings) plus second pair of legs |
| Metathorax | Third pair of legs plus hind wings |
Therefore, the correct answer is Mesothorax.

- RNA interference
- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

Concepts Used:
Anatomy of Dicotyledonous and Monocotyledonous Plants
Dicot Root:
- Dicot plants have the taproot system.
- The outermost layer is called the epidermis. The epidermal cells sometimes project out which appear as the root hairs.
- The epidermis is followed by the multi-layered cortex, loosely made of the parenchyma cells with intercellular spaces.
- The inner layer of the cortex is called endodermis, which is tightly packed by the barrel shaped-cells.
- Endodermis is followed by pericycle, which are a few layers of thick-walled parenchyma cells.
- In dicots, the central pith is not distinct.
- There are two to four xylem and phloem.
- The xylem and phloem are remarked by a layer of parenchymatous cells known as conjunctive tissue.
Monocot Root:
Monocot roots do not show much difference in the anatomy from that of the dicot roots.
- Monocot plants possess an adventitious root system.
- As in the dicots, the epidermis forms the outermost layer, followed by cortex, pericycle, endodermis, vascular bundles (xylem and phloem) and pith (random order).
- Pith is conspicuous and large.
- The number of xylem in a monocot is six or more.
- Secondary growth is not seen in the monocot plants.
