Why was Robert Brown astonished to see that pollen from a dead plant moved around in water?
Robert Brown was astonished to see that pollen from a dead plant moved around in water because it exhibited constant, random motion, a phenomenon later known as Brownian motion. This unpredictable movement suggested that even inanimate particles were influenced by unseen forces, leading him to ponder the nature of matter. His observations laid the groundwork for later developments in atomic theory and the understanding of molecular motion.

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.
Who discovered particle movement in water?
The movement of particles in water was first observed by the botanist Robert Brown in 1827, a phenomenon now known as Brownian motion. Brown noticed pollen grains jiggling in water under a microscope, which was later explained by the random collisions of water molecules with the pollen particles.
What is the father and mother name of Robert brown?
Robert Brown's father was James Brown and his mother was Helen Brown.
The invention of scientist robert brown?
Robert Brown was a Scottish palaeobotanist and botanist who as the first or the pioneer in using a microscope in studying. He was known because of his numerous great contribution like the Brownian motion and cell nucleus.
IN MIDDLE OF lillies is brown pollen tines what should you do with them?
It is best to remove the brown pollen tines from the lilies to prevent them from staining the petals or causing them to wilt prematurely. Gently pluck them off using your fingers or a pair of tweezers to keep the flowers looking fresh for longer.
How did Robert brown make his discovery?
Robert Brown made his discovery of Brownian motion by observing pollen grains under a microscope in 1827. He noticed that the pollen grains were constantly in a jittery, random motion, which he later attributed to the motion of water molecules in the surrounding solution pushing the pollen grains.
Who discovered brownian motion?
When Robert Brown used a microscope to look at pollen grains suspended in water in 1827, he observed that the pollen grains were constantly moving around as if they were being jostled by something. The particle model explains this so-called Brownian motion as being caused by water particles, which vibrate and are able to move, bumping the pollen grains.
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.
Who was Brownian motion named after?
Brownian motion is named after the Scottish botanist Robert Brown, who first observed the random motion of pollen grains suspended in water in 1827.
What did Robert brown see under his microscope when he was looking at pollen grains floating on water?
Robert Brown observed tiny particles within the pollen grains moving in a rapid, erratic motion. This phenomenon, now known as Brownian motion, is caused by the random collisions of water molecules with the pollen grains.
What did Robert brown think could be causing brownian motion?
Robert Brown thought that the random movement of pollen grains in water, known as Brownian motion, was caused by unseen particles in the water colliding with the pollen grains. This led him to propose the existence of atoms or molecules, which was later confirmed by modern science.
What did Scottish scientist Robert Brown observed in the suspended pollen grain?
Brown observed small, random movements of the particles. Such motion, which was observed in many other places, was named Brownian motion in his honor. Please see Related Links for more on Robert Brown and Brownian motion.
Where was the Brownian motion discovered?
Brownian motion was discovered by the Scottish botanist Robert Brown in 1827 while studying pollen grains suspended in 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.
Who discovered particle movement in water?
The movement of particles in water was first observed by the botanist Robert Brown in 1827, a phenomenon now known as Brownian motion. Brown noticed pollen grains jiggling in water under a microscope, which was later explained by the random collisions of water molecules with the pollen particles.
Who discovered random movement of particles?
The random movement of particles, known as Brownian motion, was discovered by the Scottish botanist Robert Brown in 1827 while observing the movement of pollen grains suspended in water under a microscope.
Why was Robert Brown unable to work out that water particles were making pollen move?
Robert Brown observed the erratic movement of pollen grains under a microscope, which he attributed to either heat or agitation. Because he did not witness the same movements in non-living particles, he concluded that the motion was due to some intrinsic property of living organisms rather than external factors like water particles.
