Question

How do flowering plants reproduce?

Answer 1

Sexual reproduction in flowering plants:

1. Sexual reproduction is the most common way of reproduction for angiosperms.
2. In angiosperms, a flower is a reproductive organ.
3. A flower might have male or female reproductive organs or both.
4. Flowers perform sexual reproduction in plants by fusing male and female gametes to produce seeds that yield fruit.
5. The seeds germinate and sprout into new plants.

A flower's male and female components-

1. The male component of the flower is called Androecium.
2. The anther, made up of tube-like structures with a slightly inflated end, includes stamens.
3. This is where the pollen grains are found.
4. When the plant is young, they stay here, and when it matures, they reach out to the female end for fertilization.
5. The feminine component of the flower is known as the gynoecium.
6. It contains pistils that travel through a tube to the ovary (known as style).
7. The pollen grains produced by the anther can be captured by the style's swollen end.
8. Ovules are found in the ovary in this plant region.
9. Ovules become seeds after fertilization, which hatch into new blooms or fruits.

The following steps in plant pollination cause sexual reproduction:

1. Pollination is the process in which pollen grains are transferred from anther to stigma.
2. Pollination can be achieved by biotic or abiotic agents.
3. Male microgametophytes that produce male gametes are pollen grains.
4. Pollen grains must be delivered to the flower's stigma via the anthers.
5. The ovule, or female gametophyte, is contained in the stigma, which generates the zygote when it unites with the pollen grains or male gametophyte.
6. Self-pollination, which occurs within the same flower or between blooms of the same plant, or cross-pollination, which arises between flowers of different plants of the same species, are two types of pollination.

Formation of Zygote:

1. Male and female gametes unite to create the zygote at the ovary of the flower's pistil after pollen grains are transferred.

Fruit and seed development:

1. An embryo develops from the zygote generated by the union of gametes.
2. The fruit tissue grows from the carpels of the flower.
3. The ovary matures into a fruit, and the ovules within bear the flower's seeds.
