pollen grains are attracted by a magnetic force
When pollen grains are placed in a 10 percent sugar solution, they will absorb water from the solution through osmosis. This can cause the pollen grains to swell and become turgid. The sugar solution provides a hypertonic environment, leading to an influx of water into the pollen grains.
Pollen grains
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
Microspores mature into pollen grains in seed plants as part of the process of microgametogenesis. Pollen grains play a crucial role in the reproductive cycle of plants by carrying male gametes to the female reproductive structures.
Sporopollenin is complex compound present in the exine of pollen grains. As such, it can be extracted from pollen grains.
Pollen grains collide with water molecules, which results in the zigzag motion known as Brownian motion. The constant collisions from water molecules exert random forces on the pollen grains, causing them to move in unpredictable paths.

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
No, pollen grains are not formed within the stigma. Pollen grains are formed in the anthers of a flower's stamen. The stigma is part of the female reproductive structure of a flower, where pollen grains land and germinate to fertilize the ovules.
During self pollination, pollen grains move from the stamen of a flower to its pistil. Cross pollination involves flowers from different plants.
Horsetail does not have pollen grains. However its spores are surrounded by wedge shaped elators which make them move from the sporangium with the help of wind and water.
Robert Brown discovered the motion of moving pollen grains. Although, a theory not long after was found out by Albert Einstein was that the water particles (very hard to see, pretty much invisible) were making these pollen grains move.
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.
