Select the incorrect match

Options

A. Double fertilisation – Nawaschin
B. Monocot embryo – 6-10 celled suspensor
C. Central cell – Largest cell of embryo sac
D. Antipodals – Absent in Oenothera type

Answer

To solve the question of selecting the incorrect match, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand the Concept of Double Fertilization**:
- Double fertilization is a unique process in flowering plants where one male gamete fertilizes the egg to form the zygote, and the other male gamete fuses with two polar nuclei to form the endosperm.
- The match of double fertilization with the Nivasa gene is correct, as the Nivasa gene was the first identified gene related to this process.

2. **Examine the Monocot Embryo**:
- The monocot embryo is known to have a suspensor that typically consists of 4 to 6 cells.
- The statement that it has 6 to 10 cell suspensors is incorrect, making this the likely candidate for the incorrect match.

3. **Analyze the Central Cell**:
- The central cell, also known as the polar nuclei, is indeed the largest cell in the embryo sac due to its highly vacuolated cytoplasm rich in food reserves.
- This match is correct.

4. **Look into Antipodal Cells**:
- Antipodal cells are part of the female gametophyte and are indeed absent in the Oenothera type of plants.
- This match is also correct.

5. **Conclusion**:
- Based on the analysis, the incorrect match is the one that states the monocot embryo has a 6 to 10 cell suspensor, as it should only have 4 to 6 cells.

### Final Answer:
The incorrect match is the monocot embryo having a 6 to 10 cell suspensor.
