Question

why pollen grains move zig Zag motion in water?
​

Answer 1

Answer:

They do this because they are bombarded by the other moving particles in the fluid. Larger particles can be moved by light, fast-moving molecules. Brownian motion is named after the botanist Robert Brown, who first observed this in 1827. He used a microscope to look at pollen grains moving randomly in water.
