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 is the process of transfer of pollens from anther to stigma is known as ?

Pollination

The correct answer is Option (4)- Pollination

Pollination is the process by which pollen grains are transferred from the anther (the male part of a flower) to the stigma (the female part of a flower). This process is crucial for fertilization to occur, as it allows the pollen to reach the ovules within the ovary.
