Question

Double fertilization is a characteristic feature of which group of plants?

• A. Bryophytes
• B. Gymnosperms
• C. Pteridophytes
• D. Angiosperms

Hint:

*Key concept:* Double fertilization occurs in angiosperms and is essential for seed development. One sperm forms the zygote, and the other forms the endosperm. *Remember:* It’s only in angiosperms, not in other plant groups like Bryophytes or Gymnosperms.

Answer 1

The Correct Option is D

Double fertilization is a unique and characteristic feature of Angiosperms. This process involves two fertilization events occurring within the ovule.

Explanation:

During double fertilization in angiosperms:

1. One sperm cell fertilizes the egg cell, forming a diploid zygote.
2. The other sperm cell fuses with two polar nuclei, forming a triploid cell, which develops into the endosperm. The endosperm serves as nourishment for the developing embryo.

Double fertilization is exclusive to angiosperms and does not occur in other plant groups like bryophytes, gymnosperms, or pteridophytes.
