Which one of the following is incorrectly matched.

Options

A. Pulvinus-Leaf base
B. Rachis-Midrib of the leaf
C. Pneumatophores-Respiratory root
D. Scutellum-modified endosperm

Answer

To determine which option is incorrectly matched, we will analyze each term and its corresponding definition.

1. **Pulp Venus**: This term refers to the leaf base that connects the leaf to the stem. It is indeed a point of attachment for the leaf. This match is correct.

2. **Rachis**: The rachis is the central stem of a compound leaf, from which leaflets arise. It is also referred to as the midrib of the leaf. This match is correct.

3. **Respiratory Roots**: These roots are specialized roots that grow above the ground in certain plants, such as Rhizophora, to facilitate gas exchange in saline environments. This match is correct.

4. **Scutellum**: The scutellum is a part of the seed in monocots, specifically known as the seed leaf that aids in nutrient absorption. It is not a modified endosperm, which is a different structure. Therefore, this match is incorrect.

Based on the analysis, the incorrectly matched term is **Scutellum**, as it is incorrectly described as a modified endosperm.

**Final Answer**: The incorrectly matched term is **Scutellum - Modified Endosperm**.
