Question

The fertilization in plants was discovered by

• A. Strasburger
• B. Nawaschin
• C. Hoffmeister
• D. Leeuwenhoek

Answer 1

Answer: (A)

Strasburger

The fertilization in plants was discovered by Strasburger. He also indicated the process of double fertilization. The process involves the fusion of pollen grains produced in the anther to the ovules in the ovary. The pollen grains are transferred from the anther of the flower to the stigma of the flower. The pollen grains forms a pollen tube and enters the style and reaches the ovary and finally fuses with ovules. One sperm cell of a pollen grain fertilizes an egg cell while second fuses with two polar nuclei to produce a triploid body that gives rise to the endosperm. This process is known as double fertilization.

So, the correct answer is option A.
