Sexual Reproduction in flowers
Therefore, to understand the process of reproduction in flowering plants, we need to look at the different parts of the flower and their functions
Flowering plants, also called angiosperms, use a sexual mode of reproduction. Reproduction in plants, mainly revolves around the flower, which has both the male and the female gametes.
All parts of a flower aid in the process of reproduction, although some of them are sterile.

Functions of a Flower

They are the modifications of a shoot. Angiosperms of flowers are shaped differently, helping diverse modes of pollination.
Flowering plants are heterosporous. They mainly produce two types of spores. Megaspores are produced inside ovules and Microspores are produced by meiosis inside anthers.
Flowers provide development of the pollen tube, base germination of pollen, the formation of gametes and fertilization. The ovarian portion of the carpel is supplied into the fruit. The ovules are converted into seeds after fertilization. The gametophytes also develop inside the spores in case of heterosporous plants.
The flowers that lack one or the other reproductive organ are called unisexual or imperfect. In ovaries, the different modification helps in the dispersal of seeds and fruits in some floral parts like a calyx. !
