Understanding Perisperm and Its Characteristics
Perisperm is a tissue found in certain seeds, and its classification can often lead to confusion. Let's analyze the assertion and reason provided.
Assertion (A): Perisperm is a haploid tissue.
- This assertion is false.
- Perisperm is a triploid tissue, derived from the fusion of sperm with multiple nuclei of the central cell in the ovule. Thus, it contains three sets of chromosomes.
Reason (R): Perisperm is the remains of nucellus which surround the embryo in certain seeds.
- This reason is true.
- The perisperm does indeed originate from the nucellus, which is the tissue that encases the embryo sac in the ovule. In some seeds, the perisperm surrounds the developing embryo and provides additional nourishment.
Conclusion
- Since assertion (A) is false and reason (R) is true, the correct choice is option D: "Assertion (A) is false but reason (R) is true."
Key Takeaway
- Understanding the distinction between haploid and triploid tissues is crucial in plant biology.
- Perisperm’s role in seed development is significant, as it serves as a nutrient source for the embryo.
This knowledge is fundamental for examinations like NEET, where clarity on plant reproductive structures is tested.
