Example of ployloid tissue present in an angiosperm plant is

Options

A. Perisperm
B. Embryo
C. Sporophyte
D. Placenta

Answer

To determine an example of polyploid tissue present in an angiosperm plant, we can analyze the options provided:

1. **Understanding Polyploidy**:
- Polyploidy refers to a condition in which an organism has more than two complete sets of chromosomes. This is different from haploidy (one set of chromosomes) and diploidy (two sets of chromosomes).

2. **Analyzing the Options**:
- **Perisperm**: This is a tissue that nourishes the developing embryo in some seeds. It is typically diploid (2n), meaning it does not qualify as polyploid. Therefore, this option is incorrect.

- **Embryo**: The embryo is formed from the fertilization of male and female gametes, resulting in a diploid structure (2n). Thus, this option is also incorrect.

- **Sporophyte**: The sporophyte generation in plants is the diploid phase that produces spores through meiosis. In angiosperms, the spores can be polyploid, as they can have multiple sets of chromosomes. Therefore, this option is correct.

- **Placenta**: The placenta in flowering plants is the tissue that connects the developing embryo to the parent plant and is also diploid (2n). Hence, this option is incorrect.

3. **Conclusion**:
- After analyzing all the options, the only example of polyploid tissue present in an angiosperm plant is the **sporophyte**.

### Final Answer:
The example of polyploid tissue present in an angiosperm plant is **sporophyte**.
