Question

Which of the following statement defines double fertilisation?

• A. Fusion of male gamete with antipodal cell
• B. Fusion of male gamete with synergid cell
• C. Fusion of male gamete with egg cell
• D. Fusion of one male gamete with egg cell and another with secondary nuclei

Answer 1

The correct option is D Fusion of one male gamete with egg cell and another with secondary nuclei

During flowering plant reproduction, two structures are created: a zygote and the endosperm. A zygote will grow and develop into an embryo, or baby plant. The endosperm is the plant embryo's food source. This process of forming a zygote and endosperm is called double fertilization. The zygote formed will be diploid in nature whereas the endosperm will be triploid in nature.

So, the correct answer is option D.
