Which of the following statement is correct regarding diffusion?
Diffusion takes place only in gases. Movement of substances takes place from low concentration to high concentration. Movement of substances takes place from high concentration to low concentration.
Which of the following statement is true about simple diffusion?
Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.
Which of the following is false in regard to facilitated diffusion?
Which of the following is FALSE in regard to facilitated diffusion? Facilitated diffusion requires the hydrolysis of ATP. A selectively permeable membrane separates two solutions. Water is able to pass through this membrane; however, sucrose (a disaccharide) and glucose (a monosaccharide) cannot pass.
Which of the following statements is true the process of diffusion can be reversed?
Which of the following statements is true? The process of osmosis can occur in the absence of a selectively permeable membrane. The process of diffusion cannot take place without a membrane present. The process of diffusion can be reversed, but only if a strong force is applied.
What is the correct definition of diffusion?
Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.
Which statement is wrong about diffusion?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.

Which is true of simple diffusion?
Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.
Which of the following is true for diffusion?
Diffusion requires energy input from the cell. Only water can diffuse across a cell membrane. Molecules move from areas of high concentration to areas of low concentration.
Which of the following describes simple diffusion?
Simple diffusion is the process by which solutes are moved along a concentration gradient in a solution or across a semipermeable membrane. Simple diffusion is carried out by the actions of hydrogen bonds forming between water molecules and solutes.
Which of the following is incorrect about facilitated diffusion?
Facilitated diffusion cannot cause net transport of molecules from a low to a high concentration, this would require an input of energy which is a characteristic of active transport.
Which of the following is true for facilitated diffusion?
The correct answer is C. facilitated diffusion involves movement that is passive and down a concentration gradient
What Does facilitated diffusion?
In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.
What are the characteristics of facilitated diffusion?
Basic Features Facilitated diffusion is a passive process that requires no use of external energy. The action of facilitated diffusion is spontaneous, however, the rate of the diffusion differs according to how permeable a membrane is for each substance.
Which of the following statement is true about diffusion?
Diffusion takes place only in gases. Movement of substances takes place from low concentration to high concentration. Movement of substances takes place from high concentration to low concentration.
Which of the following is correct for diffusion?
The correct answer is 3 i.e. The rate of diffusion increases on increasing with the temperature of the diffusing substance. Details about the process of Diffusion: The spreading out and mixing of a substance with another substance due to the motion of its particles is called diffusion.
Which of the following statement is correct about diffusion and osmosis?
(i) In osmosis, a semipermeable membrane is used while diffusion is without membrane. (ii) In osmosis, movement of molecules occurs in one direction while in diffusion, movement occurs in all directions. (iii) In osmosis, only the solvent moves while in diffusion both solute and solvent move
Is diffusion the opposite of osmosis?
Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely. Osmosis happens when molecules move from higher to lower concentrations, but diffusion happens when it is reversed
What is the correct definition for simple diffusion?
In biology, simple diffusion is a form of diffusion that does not require the assistance of membrane proteins. In essence, the particle or substance moves from higher to lower concentration. However, its movement does not need a membrane protein that will help substances to move downhill.
Which statement is correct diffusion?
Diffusion takes place only in gases. Movement of substances takes place from low concentration to high concentration. Movement of substances takes place from high concentration to low concentration.
What is the most common definition of diffusion?
Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient. Diffusion is an essential process, which is involved in the different life processes.

Which of the following statement is not true about diffusion?
The correct answer is (c) Rate of diffusion of gases depends on their volume. Rate of diffusion of gases does not depends on their volume. Diffusion is the process of particles moving from highly concentrated region to low concentrated region. Diffusion is only possible when the matter moves continuously.
What is correct regarding diffusion?
The correct option is B. Movement of substances takes place from high concentration to low concentration. Diffusion is the spontaneous movement of a substance from a region of high concentration to a region of low concentration. It takes place in gases as well as liquids.
Which of the following statements hold true for both diffusion and osmosis?
Explanation:A) both diffusion and osmosis does not need energy. But osmosis is the movement of water molecules from higher concentrations to lower concentrations through a semipermeable membrane.
