Perisperm differs from endosperm in:
Correct answer: A. Being a diploid tissue
- A. Being a diploid tissue
- B. Its formation by fusion of secondary nucleus with several sperms
- C. Being a haploid tissue
- D. Having no reserve food
Explanation
Both perisperm and endosperm are nutritive layers. Perisperm is the residual persistent nucellus of seed prior to fertilization while endosperm develops when one of the sperm cells fuses with two haploid polar nuclei. Thus perisperm is diploid while endosperm is a triploid tissue.
