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
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 the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
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)
COMPARE osmosis and diffusion?
Diffusion is movement of molecules, from region of higher concentration, to the region of lower concentration, along 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.

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.
How would diffusion differ from osmosis?
Osmosis is the net movement of water molecules across a semipermeable membrane from a region of a lower concentration to a higher concentration. Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration down a concentration gradient

How long does movement occur across a concentration gradient?
As long as there is a concentration gradient. This is because diffusion occurs which is the net movement of substances from a region of high concentration to a region of low concentration.
What are Conditions needed to cause water to diffuse in cell?
The primary drivinf force for diffusion is a concentration gradient. There has to be an abundance of molecules at one region and a scarcity of molecules at another. This differential distribution of molecules where one region has more than the other is called a concentration gradient. In the presence of this gradient, diffusion occurs without the expenditure of energy. In cells, diffusion can occur through the cell membrane. Water molecules move into or out of the cell depending on where there are more water molecules. If there is more water outside the cell, water molecules move in and vice versa.

Some examples are diffusion and osmosis. Basically, it's a movement of molecules across a membrane that doesn't require energy (ATP)
What does it means if a substance moves down its concentration gradient?
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
