What is diffusion occurs because of the what movement of molecules?
No, diffusion does not occur because of random molecular movement. It is rather as a result of movement of molecules from areas of high concentration to lower concentration.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What is water uptake at the roots?
water uptake at the roots is called osmosis,this is the movement of water molecules from a region of lower concentration to a region of higher concentration against concentration gradient
What do you call the movement of molecules or atoms from a region of higher concentration to a region of lower concentration?
The Atomic or Molecular movements generally known as Osmotic diffusion.
What does the passive in passive transport mean?
Passive Transport is the movement of molecules down a concentration gradient from a region of high concentration to a region of low concentration until equilibrium is reached. Some examples are diffusion and osmosis. Basically, it's a movement of molecules across a membrane that doesn't require energy (ATP)
Diffusion is the process of movement of molecules under a concentration gradient?
Yes
What does it mean when you are going with the concentration gradient?
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration
COMPARE osmosis and diffusion?
Diffusion is movement of molecules, from region of higher concentration, to the region of lower concentration, along concentration gradient.
What type of molecule movement involves the use of ATP?
Active transport. This is movement of molecules against the concentration gradient.
What is diffusion occurs because of the what movement of molecules?
No, diffusion does not occur because of random molecular movement. It is rather as a result of movement of molecules from areas of high concentration to lower concentration.
Compare osmosis diffusion and filtration?
Diffusion is movement of molecules, from region of higher concentration, to the region of lower concentration, along concentration gradient.
What is diffusion in science terms?
In biology, diffusion is the passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration. Diffusion is the free movement of particles in a liquid or gas down a concentration gradient.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
Why does the concentration gradient affect osmosis?
Because osmosis is the movement of water molecules from where they are in high concentration to where they are in low concentration.
What is water uptake at the roots?
water uptake at the roots is called osmosis,this is the movement of water molecules from a region of lower concentration to a region of higher concentration against concentration gradient
Why osmosis is a type of diffusion?
Because it is the movement of molecules from areas of high concentration to areas of low concentration in the direction of the concentration gradient. Osmois specifically implies the diffusion of water.
Difference between molecular motion and diffusion?
It triggers diffusion because diffusion is the movement of molecules, therefore as soon as the molecules move diffusion begins to do it's job. It will take them from areas of greater concentration to areas of lesser concentration.
