Question

What is a bisexual flower? Collect five bisexual flowers from your neighbourhood and with the help of your teacher find out their common and scientific names.

Answer 1

Hint: Flower plants are characterized into many types under many conditions. The bisexual flower is a classification of the flower based on the flower containing the reproductive parts of the plant. The androecium and gynoecium are the reproductive parts of the flower.

Complete answer:
A bisexual flower is one that contains both male and female reproductive organs. The male reproductive part is known as androecium and the female reproductive part is known as the gynoecium. A bisexual flower contains all the components of a flower, calyx, corolla, stamens, and carpel.
The androecium is made up of anther and filament which contains pollen grains that contain gametes.
The gynoecium is the female reproductive part containing style, stigma, and ovary.

A bisexual plant is more likely to undergo self-pollination whether it be geitonogamy or autogamy but cases of cross-pollination have also been seen. When both the reproductive parts of the same flower do not mature at the same time, cross-pollination is the only option.

Different types of flowers are found around us, you can collect any of the following-
> Rose
Common name- rose
Scientific name - Rosa multiflora
> Water lily
Common name- water lily
Scientific name- Nymphaea odorata
> Hibiscus
Common name- china rose, hibiscus
Scientific- Hibiscus Rosa-Sinensis
> Mustard
Common name- mustard flower
Scientific name- Brassica nigra
> Petunia
Common name- petunia
Scientific name- Petunia hybrida

Note:
The ovules are the female gametes which are fertilized by the pollen to form seed. The ovary containing the ovules gets transformed into the fruit containing the seeds. The bisexual flowers help in maintaining genetic purity but since there is no variation the plant’s genetic constitution can degrade after several progenies.
