Question

Is pollen haploid or diploid?

Answer 1

Pollen:

1. Pollen is a powdery substance made up of pollen grains, which are male microgametophytes that form male gametes in seed plants (sperm cells).
2. Microsporogenesis produces pollen grains.
3. The microsporangium's diploid pollen mother cells divide via meiosis to produce four haploid microspores or microspore tetrads. After dissociating from one another, microspores mature into haploid pollen grains.
4. In plants and trees, pollen grains primarily represent the male element of the reproductive process.
5. Pollen is utilized by plants to transfer haploid male genetic material from one flower's anther to the stigma of another, a process known as cross-pollination.
6. In the instance of self-pollination, the process occurs from the anther of one bloom to the stigma of another flower.
7. So, pollen is the haploid structure.
