the structure which can show the effedt of traits brought by the male gamete immediately after its formation is

Options

A. Embryo
B. Cotyledons
C. Endosperm
D. Plumule.

Answer

To solve the question regarding the structure that shows the effect of traits brought by the male gamete immediately after its formation, we can analyze the provided options step by step.

### Step-by-Step Solution:

1. **Understanding the Question**:
The question asks for the structure that demonstrates the effects of traits from the male gamete right after it is formed.

2. **Analyzing Option A - Embryo**:
- The embryo is formed from the fusion of male and female gametes, resulting in a zygote.
- The zygote contains genetic material from both parents and develops into the embryo through mitotic divisions.
- **Conclusion**: The embryo does not show the effects of traits from the male gamete immediately after its formation, as it includes traits from both gametes.
- **Status**: Incorrect.

3. **Analyzing Option B - Cotyledons**:
- Cotyledons are part of the seed and serve as storage for reserve food material.
- They provide nourishment to the developing embryo but do not directly reflect the traits of the male gamete.
- **Conclusion**: Cotyledons do not show the effects of the male gamete immediately after its formation.
- **Status**: Incorrect.

4. **Analyzing Option C - Endosperm**:
- The endosperm is formed through a process called triple fusion during double fertilization in angiosperms.
- One male gamete fuses with the egg to form the zygote, while the other fuses with the diploid secondary nucleus to form the endosperm.
- The endosperm provides nourishment to the developing embryo and is formed immediately after fertilization.
- **Conclusion**: The endosperm shows the effects of the male gamete right after its formation, as it is crucial for nourishing the embryo.
- **Status**: Correct.

5. **Analyzing Option D - Plumule**:
- The plumule is part of the embryo that develops into the shoot.
- It does not show the effects of the male gamete immediately after its formation, as it is a later development from the embryo.
- **Conclusion**: The plumule does not reflect the immediate effects of the male gamete.
- **Status**: Incorrect.

### Final Answer:
The correct answer is **Option C - Endosperm**.
