In most angiosperms (flowering plants), chloroplasts are maternally-inherited. Pollen grains (male seed) do not contain chloroplasts.
Sporopollenin is complex compound present in the exine of pollen grains. As such, it can be extracted from pollen grains.
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
Pollen grains are formed within the anthers of flowering plants, which are the male reproductive structures where pollen grains develop and mature. The process of pollen grain formation is called microsporogenesis.
Pollen grains
Pollen grains are often called as microspores or male gametes. They are produced in pollen sacs present in pollen chambers in the anthers of the flower. They are produced due to repeated division of microspore mothercells and are haploid (n).

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.

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 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.
