What else can I help you with?
Name 2 types of passive transport?
Diffusion-the random movement of molecules from an area of higher concentration to an area of lower concentration.Osmosis-the diffusion of water across a semipermeable membrane.
How does charge affect diffusion?
A concentration gradient is a difference in concentration across a space. It affects diffusion and osmosis because both of these passive transports move down their concentration gradients, or from an area of high concentration to low concentration.
Does facilitated diffusion move a substance following its concentration gradient with the aid of a carrier protein?
No.All diffusion, including facilitated diffusion, results in a substance spreading out, so there is a general (net) movement away from higher concentrations to lower ones."Facilitated" just means that special proteins in the cell membrane let substances through that could not get through any other part of the membrane. It's like wanting to get the other side of a wall. A door facilitates your progress!
What are molecules that tend to move form an area of high concentration?
Molecules that tend to move from an area of high concentration to an area of low concentration are said to undergo passive transport or diffusion. This process occurs naturally due to the random movement of molecules and does not require additional energy input from the cell.
Can glucose pass through a membrane?
Dialysis membranes are typically not permeable to sucrose. Removing sugar from the blood can be dangerous as it can lead to hypoglycemia. Sugar molecules are too large to pass through dialysis membranes.
What are metaphors for 'diffusion'?
Diffusion is the movement of a mineral or nutrient moving across the concentration gradient of a membrane. The closest word to diffusion would probobly be osmosis, which is the movement of water through a membrane.
What is it called when particles travel from an area of high concentration to an aera of low concentration?
Through passive transport
How are osmosis and diffusion different?
Diffusion is the net movement of a substance through a membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.

What is the difference between simple diffusion and facilitated diffusion?
It doesn't. (answer by RRU member Cyrem)
Why is it called osmosis rather than diffusion?
Osmosis specifically refers to the movement of water molecules through a semi-permeable membrane, while diffusion is a more general term that applies to the movement of any type of molecule from an area of high concentration to low concentration. Osmosis is a type of diffusion specific to water molecules.
How does charge affect diffusion?
A concentration gradient is a difference in concentration across a space. It affects diffusion and osmosis because both of these passive transports move down their concentration gradients, or from an area of high concentration to low concentration.
Do diffusion include osmosis?
Diffusion and osmosis are both processes by which molecules move from an area of high concentration to an area of low concentration. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane, while diffusion is a more general term that refers to the movement of any type of particle (not just water).
Does a force vector describe the direction and the speed of a force?
Yes, basically. But please note that there is no such thing as the "speed of a force". A force vector describes the magnitude of a force, and its direction. In general, a physical vector - the vectors commonly used in physics - describes the magnitude of something, and its direction.
Are diffusion and osmosis the same process?
No osmosis is actually a special term used just for the movement of water across a cell membrane. We don't use that term for anything else. Diffusion is for the movement of other substances but not always involving a cell membrane. For example, scent can diffuse in the air. Science tends to be like this but it is important to use exact terms.
What is the tendency of fluids to move through a membrane?
The tendency of fluids to move through a membrane is known as osmosis. It occurs when there is a concentration gradient of solutes on either side of the membrane, causing water to move from an area of lower solute concentration to an area of higher solute concentration in order to achieve equilibrium.
How is osmosis related diffusion?
Osmosis and diffusion are similar in that there is a net movement of molecules from a high concentration of those molecules to a lower concentration. Osmosis is a special type of diffusion that deals with the movement of water only. Osmosis also deals with a semipermeable membrane (like our cell membranes). Diffusion can occur anywhere such in a glass of water when you add sugar but it can occur around cells.
