Read the following statements and select the correct option.
Statement-I : In gymnosperms, endosperm is formed before fertilization and is haploid
Statement-II: In angiosperms, endosperms is formed after fertilization and is diploid

Options

A. both statements I and II are correct
B. both statements I and II are incorrect
C. statements I is correct and statement II is incorrect
D. statements II is correct and statement I is incorrect

Answer

To solve the question, we need to analyze both statements provided:

**Statement-I**: In gymnosperms, endosperm is formed before fertilization and is haploid.

1. **Understanding Gymnosperms**: In gymnosperms, the endosperm is indeed formed from the female gametophyte, which is haploid. This process occurs before fertilization.

2. **Conclusion for Statement-I**: This statement is correct because the endosperm in gymnosperms is formed before fertilization and is haploid.

**Statement-II**: In angiosperms, endosperms are formed after fertilization and are diploid.

1. **Understanding Angiosperms**: In angiosperms, the endosperm is formed after fertilization. The endosperm is created from the fusion of a haploid male gamete with the diploid central cell (which contains two polar nuclei), resulting in a triploid endosperm.

2. **Conclusion for Statement-II**: This statement is incorrect because the endosperm in angiosperms is triploid, not diploid.

**Final Evaluation**:
- Statement-I is correct.
- Statement-II is incorrect.

Thus, the correct option based on the evaluation of both statements is that Statement-I is true and Statement-II is false.
