The main parts of a flower include the stock, thalamus, petals, saes (green leaf-like structures), stemons (male reproductive organ), and carpel (female reproductive organ).

Q: Why do flowers have petals?

Petals serve two main functions: attracting insects for pollination and protecting the internal reproductive organs of the flower.

Q: What is the role of insects in the process of sexual reproduction in plants?

Insects play a crucial role in pollination by transferring pollen grains from the stemon (male reproductive organ) to the carpel (female reproductive organ), enabling the fusion of male and female gametes.
