Pollen grains come in different sizes depending on the plant species. Larger grains tend to be heavier and have a harder time being carried by wind, so they are usually found in plants that rely on insects for pollination. Smaller pollen grains are adapted for wind dispersal, allowing them to travel further distances.
No, pollen grains are haploid in nature.
Pollen grains are produced by the male reproductive organs of flowering plants called anthers. Anthers contain pollen sacs where pollen grains develop and mature.
A pollen sac is found in the anther of a flower, which contains pollen grains. Each anther typically has two pollen sacs, known as microsporangia, where pollen grains are produced via meiosis.
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.
Stalks are structures that support the pollen grains in flowers. They connect the pollen grains to the anther, where the pollen is produced, and help in the dispersal of pollen for plant reproduction.
Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.
In cross pollination there is wastage of pollen grains , but in self pollination there is no wastage of pollen grains.
Pollen grains
pollen grains are little grains in side a flower
No, pollen grains are haploid in nature.
The anther is the part of the stamen that contains the pollen grains. These pollen grains are the male reproductive cells that are essential for the process of pollination.

pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.
Pollen grains are the microscopic male reproductive particles released from flowering plants. As these grains are vital for the survival of flowering species, evolution has ensured that individual species produce different types of pollen grains. Pollen grains are also made of a resistant organic material (sporopollenin) that means they are often remarkably well-preserved in sediments many thousands of years old.
Stalks are structures that support the pollen grains in flowers. They connect the pollen grains to the anther, where the pollen is produced, and help in the dispersal of pollen for plant reproduction.
