Question

Which part of a Plant produces Pollen?

Answer 1

Hint Pollen grains are small particles that contain androecium, a flower's male reproductive organ. The tube cell turns into a pollen tube and the generative cell releases the sperm nuclei in the interior region of the pollen grain, which contains cytoplasm.

Complete answer:
Male gametes are delivered into female reproductive organs by pollinators, honey bees, bats, birds, butterflies, flower beetles during fertilisation, and the end result is the creation of an embryo in a seed.
A stamen is made up of two parts: a filament and an anther that contains microsporangia. Anthers are usually two-lobed and are joined to the filament at the base or in the middle of the anther. The connective tissue is a sterile tissue that runs between the lobes and is an extension of the filament that contains conducting strands.
On the dorsal side of the anther, it appears as an extension. The male gametophyte is contained in a pollen grain that grows from a microspore in the microsporangium.
Some or all of the stamens in a flower may be linked to the petals or the floral axis, depending on the plant type. They can either stand alone or be fused to one another in a variety of ways, including the fusing of some but not all stamens.
The filaments can be fused while the anthers are left unfused, or the filaments can be left unfused while the anthers are fused. Instead of having two locules, one stamen's locule may fail to develop, or the two locules may fuse late in development to form a single locule.

The tapetum, a nutritive tissue layer that lines each microsporangium, includes diploid pollen mother cells at first. These go through meiosis and produce haploid spores. After meiosis, the spores may remain united in a tetrad or may split. Each microspore subsequently divides mitotically to generate a pollen grain, which is an immature microgametophyte.

Note: Four microsporangia are found in a typical anther. In the anther, microsporangia form sacs or pockets (locules) (anther sacs or pollen sacs). An anther's two distinct locules on each side may combine to form a single locule.
