Question

In which of the following species of angiosperms, the process of double fertilization was discovered?

• A. Datura and Solanum
• B. Michelia and Papaya
• C. Lilium and Fritillaria
• D. Sida and Malva

Hint:

Double fertilization is a hallmark feature exclusive to angiosperms.

Answer 1

The Correct Option is C

Step 1: Understanding double fertilization.
Double fertilization is a unique feature of angiosperms in which two male gametes participate in fertilization—one fuses with the egg cell and the other fuses with the polar nuclei to form endosperm.
Step 2: Historical discovery.
The phenomenon of double fertilization was first discovered by Nawaschin in angiosperms belonging to the genera Lilium and Fritillaria.
Step 3: Analysis of options.
(A) Incorrect — not the plants in which discovery was made.
(B) Incorrect — these are angiosperms but not historically associated with the discovery.
(C) Correct — double fertilization was first observed in Lilium and Fritillaria.
(D) Incorrect — not related to the discovery of double fertilization.
Step 4: Conclusion.
Double fertilization was discovered in Lilium and Fritillaria.
