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)
What type of molecular movement is it if movement of molecules is against the concentration gradient from low to high through protein pumps?
Active Transport
How can diffusion occur in one direction?
Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.Explanation:Diffusion is a passive process. It is like when you open a bottle of perfume, soon the whole room will be covered with its smell. From region where the concentration is high, the molecules move to the regions where the concentration is low down the concentration gradient unless equilibrium is reached. Diffusion is the net movement of molecules from the region of higher concentration to region of 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
Diffusion continues until there is no?
Concentration gradient. After there's no concentration gradient, equilibrium occurs, which means no more diffusion.
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.
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 Equal movement of molecules called?
The equal movement of molecules would be describing an "isotonic" state, where concentration gradients are equal, and a state of equilibrium is created.
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.
Diffusion is the movement of a substance?
from an area of high concentration to an area of lower concentration.
What type of molecular movement is it if movement of molecules is against the concentration gradient from low to high through protein pumps?
Active Transport
