Which one of the following is wrongly matched

Options

A. Cassia-lmbricate aestivation
B. Root pressure- Guttation
C. Puccinia-Smut
D. Root - Exarch protoxylem

Answer

To determine which of the following options is wrongly matched, we will analyze each option one by one:

1. **Caesia - Imbricate Extubation**:
- The term "imbricate extubation" refers to a type of flower petal arrangement where the petals overlap each other. However, in the case of Caesia, the type of petal arrangement is actually "twisted" (where one petal margin overlaps with another). Therefore, this match is incorrect.

2. **Root Pressure - Guttation**:
- Root pressure is a phenomenon that occurs when water is absorbed by the roots and creates pressure that pushes water up through the plant. This process can lead to guttation, which is the exudation of water droplets from the tips or edges of leaves. Thus, this match is correct.

3. **Puccinia - Asthma**:
- Puccinia is a genus of fungi known to cause rust diseases in plants. It does not cause asthma, which is a respiratory condition in humans. However, the match here seems to be more about the association of Puccinia with plant diseases rather than a direct link to asthma. This option is misleading but not necessarily incorrect in the context of plant pathology.

4. **Root - Axarch Protoxylem**:
- In botany, "axarch" refers to the arrangement of xylem where the protoxylem is located towards the outside of the root and the metaxylem is located towards the inside. This is indeed the case in roots, making this match correct.

Based on this analysis, the wrongly matched option is:

**Answer: Caesia - Imbricate Extubation**
