The role of stamens and pistils. What do stamens and pistils do?

The role of the stamens is to produce pollen, and the pistils are the female reproductive organs of the seed plants that receive pollen.

Seed plants produce pollen. It is composed of two parts: filament and anther. Located inside or above the perianth, it is arranged in a wheel-like or spiral shape on the receptacle.

The number varies according to the plant species, and in general, the number of primitive species is more than not, and the number of higher species tends to decrease to a certain number. All the stamens in a flower are collectively called stamens groups.

The pistil is made of carpels. Each carpel usually has 3 vascular bundles, of which the vascular bundles corresponding to the midrib of the leaf are called dorsal bundles, and the vascular bundles on both sides of the dorsal bundle are called ventral bundles. When the carpel forms a pistil, it often rolls inward, and the place where the edge of the carpel joins is called the ventral suture, and the place where there is a dorsal bundle on it is called the dorsal suture.

Classification of stamens:

1. Stamen distinct There are many stamens in a flower that are separated from each other, such as the stamens of lotus, rape, wheat and other flowers.

2. Monadelphous stamen There are 10 stamens in a flower, and their filaments are connected into a bunch to form a filigree tube, and the anthers are separated, such as the stamens of cotton, kaf, mallow, large-flowered pig dung bean, lupine and other flowers.

3. Diadelphous stamens The filigree of 10 stamens in a flower are combined into two bunches, such as the stamens of broad beans and peas, of which 9 filaments are connected into a bunch, and the other stamens are separated separately, or 5 stamens per bunch. This stamens are endemic to plants of the butterfly family (or leguminaceae).

The pistils and stamens are the organs of the plant's progeny!

Plants do not have pistils and stamens. Then they will not be able to reproduce offspring, and they will not be able to grow new plants.

Plants do not have pistils and stamens. Then they will not be able to reproduce offspring, and they will not be able to grow new plants.

Because that's what pollen needs to be transmitted through.

With pistils and stamens.

so that they may bear fruit.

The filaments of the stamens play a supporting role, and the anthers contain pollen; The stigma of the pistil has mucus to facilitate the reception of pollen, there are ovules in the ovary, the stamens include filaments and anthers, and the pistil includes the stigma, columella and ovary The stamens and pistils are collectively called stamens, and the stamens are directly related to the formation of fruits and seeds and are the main structure of the flower

Different body types. The stamens are different from the pistils, the stamens are relatively small, scattered around the pistils, and are only about 1 cm in diameter. The pistils are much larger than the stamens and occupy the center of the flower.

The quantity varies. The number of stamens and pistils is also different, and the number of stamens is more than the number of pistils. The number of stamens may reach 7-8, for example, water lilies.

There are more than 10 flower stamens, while there is only 1 pistil in ordinary flowers.

The shape is different. The stamens are generally small, very thin, and have many heads. The pistil is relatively large, and the columella is large and columnar.

The components are different.

The components of stamens and pistils are also different. Among them, the stamens are made up of filaments, anthers.

The pistil is composed of stigma, columella, and ovary.

The role is different. The role of stamens is mainly to produce pollen, and there is a lot of pollen on the anthers. The pistil has no pollen, and the stigma of the pistil has mucus, which can adhere to the pollen, and the pollen begins to grow when it falls on the stigma of the pistil, and through the pistil, it can reach the ovary and combine with the egg, thus developing into a seed.
