Reproduction in Organisms

Question:

Read the passage and answer the following questions:
After attainment of maturity, all sexually reproducing organisms exhibit events and processes that have remarkable fundamental similarity, even though the structures associated with sexual reproduction are indeed very different. The events of sexual reproduction though elaborate and complex, follow a regular sequence. Sexual reproduction is characterised by the fusion (or fertilisation) of the male and female gametes, the formation of zygote and embryogenesis. For convenience these sequential events may be grouped into three distinct stages namely, the pre-fertilisation, fertilisation and the post-fertilisation events.

What does term syngamy means?

Options:

Formation of gametes.

Fusion of gametes.

Formation of embryo .

None of these

Correct Answer:

Fusion of gametes.

Explanation:

The correct answer is Option (2)- Fusion of gametes.

Syngamy (fertilisation) occurs between the male and female gametes. The most vital event of sexual reproduction is  the fusion of gametes.This process called syngamy. The term fertilisation is also often used for this process. Syngamy may occur either externally, outside the body of organisms or internally, inside the body. Syngamy leads to formation of a specialised cell called zygote.
