What happens when pollen grains are placed in a 10 percent sugar solution?
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.
Grains that surround and protect a plants sperm?
Pollen grains
Where are pollen grains produced?
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
Microspores mature into what?
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.
How can we make sporopollenin?
Sporopollenin is complex compound present in the exine of pollen grains. As such, it can be extracted from pollen grains.
What collides with pollen grains to cause the zigzag action of Brownian motion?
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.
What happens when pollen grains are placed in a 10 percent sugar solution?
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.
What is the function of pollen grains?
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.
Grains that surround and protect a plants sperm?
Pollen grains
Are pollen grains formed within the stigma?
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.
Pollen grains move from a flower's stamen to it's pistil during what?
During self pollination, pollen grains move from the stamen of a flower to its pistil. Cross pollination involves flowers from different plants.
What pollinates horsetail?
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.
What scientist first made the observations of moving pollen grains?
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.
What are pollen grain?
pollen grains are little grains in side a flower
Are pollen grains diploid in nature?
No, pollen grains are haploid in nature.
Which part of the stamen contains pollen grains?
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.
How does the structure of the pollen grains helps it move from one flower to another?
i don't f*** know
