What else can I help you with?
Does pollination occurs when pollen grains land on the sticky surface of the anther?
No, pollination occurs when pollen grains land on the sticky surface of the stigma.
How do pollen grains move in water?
pollen grains are attracted by a magnetic force
Which structure is where pollen grains land and stick?
The structure where pollen grains land and stick is the stigma of a flower. The stigma is the uppermost part of the pistil, and its sticky surface helps to capture and hold pollen grains for fertilization.
Why did Robert brown use pollen grains experiments?
Robert Brown used pollen grain experiments to study the movement of particles in liquids which led to the discovery of Brownian motion. Brownian motion is the random movement of particles suspended in a fluid due to collisions with the fluid molecules. This phenomenon provided evidence for the existence of atoms and molecules.
Grains that surround and protect a plants sperm?
Pollen grains
What name is given to the movement of particles like pollen grains on a surface of liquids?
The name of this movement is Brownian motion.

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.
Why does the stigma have a sticky surface?
For pollen grains to stick onto during fertilization.

What is pollen analysis?
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.

What is the dust like particles produced in the anthers of flowers called?
The dust-like particles produced in the anthers of flowers are called pollen. Pollen contains male gametes that are necessary for plant reproduction when they are transferred to the stigma of a compatible flower.
