Question

The fertilization in plants was discovered by
A. Strasburger
B. Nawasachin
C. Hoffmeister
D. Leeuwenhoek

Answer 1

Plants are the multicellular eukaryotic organisms. Plants cannot move, as they are fixed at a position with the help of roots. Plants are too essential for the sustainability of life on this Earth. Because plants produce Oxygen and food with the help of the process of photosynthesis, upon which all the animals depend.

Complete Answer:
- Fertilization in flowering plants was discovered by Ralph B. Strasburger in 1884.
- He also gave the idea of double fertilization in which one of the ,male gamete fuses with ovum to form zygote and another male gamete fuses with two polar nuclei to form triploid primary endosperm nucleus.
- Fertilization is a process of sexual reproduction where both the gametes of male (pollen grains) and female(ovum) fuse with each other to form a single diploid cell called the Zygote.
- This zygote later undergoes many successive stages and at last gets developed into a seed that further develops into a new plant upon germination.
- In plants fertilization occurs by the process of pollination and germination. Flowers are the reproductive organs of the flowering plants or Angiosperms.

Additional information:
1. Contribution of Nawaschin – Nawasachin discovered the process of double fertilization in flowering plants. Double fertilization is a process in which one of the male gamete fuses with the ovum of the female and results in zygote while another male gamete fuses with two polar nuclei to form primary endosperm nucleus which later develops into the endosperm.

2. Contributor of Hoffmeister – Wilhelm Hoffmeister was the german biologist and botanist. He discovered the alternation of generations in the life cycle of plants.

3. Leeuwenhoek – Anton von Leeuwenhoek discovered a living cell. He is known as the Father of Microbiology.

Hence, option A is the correct answer for this question.

Note: Fertilization is a process that comes under the sexual reproduction which involves two opposite sexes. This process is essential for the continuity of life on the Earth. And also because of the process of sexual reproduction evolution occurs over a period of time.
