Question

Double fertilisation was first discovered in $1898$ by _________ in Fritillaria lilium.

• A. Nawaschin
• B. Strasburger
• C. Amici
• D. Focke

Answer 1

The correct option is A Nawaschin

The pollen tube that penetrates the embryo sac and enters the egg apparatus, discharges two male gametes at the tip. One of these gametes fuses with the egg cell of the egg apparatus. The other gamete fuses with the secondary fusion nucleus. This behavior of the two male gametes is termed double fertilization which was first observed by Nawaschin (1898) in Lilium and Fritilaria species.

So, the correct option is 'Nawaschin'.
