Find out the mis match

Options

A. `{:("Part","Ploidy"),("Embryo",2n):}`
B. `{:("Part","Ploidy"),("Egg",n):}`
C. `{:("Part","Ploidy"),("Endosperm",2n):}`
D. `{:("Part","Ploidy"),("Perisperm",2n):}`

Answer

To find the mismatch in the given parts and their corresponding ploidy, we will analyze each part and its ploidy status step by step.

### Step-by-Step Solution:

1. **Identify the Parts and Their Ploidy**:
- We have four parts:
1. Embryo
2. Egg
3. Endosperm
4. Perisperm
- Their corresponding ploidy is given as:
1. Embryo - 2n
2. Egg - n
3. Endosperm - 2n
4. Perisperm - 2n

2. **Analyze Each Part**:
- **Embryo**:
- The embryo develops from the zygote, which is diploid (2n).
- **Conclusion**: Correctly matched as 2n.

- **Egg**:
- The egg (ovule) is haploid (n) as it is formed from meiosis.
- **Conclusion**: Correctly matched as n.

- **Endosperm**:
- The endosperm can vary in ploidy. In gymnosperms, it is typically haploid (n), while in angiosperms, it is usually triploid (3n).
- The provided ploidy is 2n, which is incorrect for gymnosperms and not the typical case for angiosperms.
- **Conclusion**: Mismatch here as it should be n (gymnosperms) or 3n (angiosperms).

- **Perisperm**:
- The perisperm is always diploid (2n) as it develops from the nucellus after fertilization.
- **Conclusion**: Correctly matched as 2n.

3. **Identify the Mismatch**:
- The only mismatch found is with the **Endosperm**, which is incorrectly labeled as 2n. It should be either n or 3n depending on the type of plant (gymnosperm or angiosperm).

### Final Answer:
The mismatch is in the **Endosperm**, which is incorrectly labeled as 2n.
