Question

Perisperm differs from endosperm in:

• A. Its formation by fusion of secondary nucleus with several sperms
• B. Being a diploid tissue
• C. Having no reserve food
• D. Being a haploid tissue

Answer 1

The correct option is B

Being a diploid tissue

The correct option is B.

Explanation of the correct answer:

1. Perisperm and endosperm are food storing tissues of seeds in higher plants.
2. Perisperm emerges from the nucleus and is diploid.
3. Endosperm emerges from triple fusion and is triploid.

Explanation of the incorrect options:

Option A:

1. Endosperm arises due to the fusion of a male gamete with the 2 polar nuclei in the central cell.
2. Perisperm is the persistent remnants of nucellus in seeds.

Option C:

1. Both perisperm and endosperm are food-storing tissues.
2. They store food in the seeds in the form of proteins, fats, and carbohydrates.

Option D:

1. Both perisperm and endosperm are not haploid.
2. Perisperm is diploid and endosperm is triploid.

Final answer: Perisperm differs from endosperm in being a diploid tissue.
