Generally, a single flower will have several anthers and filaments.
What are the reproductive organs of a flower?
Enclosing the reproductive organs of the flower are its petals, which have no overt sexual function, but which do play a role in reproduction by emitting scents that attract bees and other pollinating insects to the flower . The insects settle on the flower to gather the sweet nectar that the plant secretes; as they do so, they spread pollen that they’ve collected from other plants onto the stigmas of the flower.

At the very top of the pistil, the stigma is the place where pollinators like bees deposit pollen grains. Some flowers have multiple stigmas. In most flowers, the stigma is just level with or slightly above the anthers. The style is the neck of the pistil, a hollow tube that leads down to the flower’s ovary at the base of the petals.
What happens when pollen lands on the stigma?
When pollen lands on the stigma, the pollen grains put out tubes, which descend down the style to the ovary. Once there, the tubes release sperm cells that fertilize the ovules, which then develop into fruits that contain seeds.

What is it called when the sepals fall off?
If the sepals are free the calyx is called polysepalous, and if they are united it is called gamosepalous. In many flowers, the sepals fall off before the flower even opens fully. Such sepals are known as caducous. In some, the sepals fall off after fertilization. Such sepals are known as deciduous.

What insects go to the flower for pollen?
When pollinating insects, such as bees and butterflies, go to the flower for pollen, they also visit the stigma. This will fertilize the flower. When pollen gets to the stigma, a tube grows down the style. This tube enters the ovary. The male reproductive cells from the anther travel through the tube and join the ovule, fertilizing it.

How do pollen grains form?
Formation of Pollen grains: The young anther soon becomes four-lobed as it comprises a homogenous mass of parenchymatous cells engirdled by the epidermis. Each archesporial initially present in hypodermal cells divides into the inner primary sporogenous cell and outer primary parietal cell. Each primary sporogenous cell splits to produce microsporocytes. Each microspore mother cell meiotically divides to form pollen grains.
What are the two types of spores in a flower?
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.
How are microspores formed?
Microsporogenesis involves the formation of microspores from microspore mother cells by meiotic division. The structure of anther: The anther is the breeding part of stamens. Each anther is connected by two lobes. Each anther lobe comprises two pollen chambers located longitudinally.
