What is diffusion quizlet bio?
Terms in this set (12) Diffusion. Movement of particles or molecules from an area of high concentration to an area of low concentration. Osmosis. Diffusion of water across a selectively permeable membrane.
What is a simple definition of 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. A familiar example is the perfume of a flower that quickly permeates the still air of a room.
What is diffusion in biology?
Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. The difference in the concentration of a substance between two areas is called the concentration gradient .
What is diffusion in AP Bio?
Diffusion is the passive movement of molecules down the concentration gradient from areas of high concentration to low concentration. Osmosis is the diffusion of water molecules across a membrane. Cell membranes are semipermeable, only allowing select molecules to pass through.
What is diffusion in sociology quizlet?
Diffusion. A social process through which cultural knowledge, practices, and materials spread from one social system to another.
What is the best definition of diffusion quizlet?
Diffusion. the random movement of molecules from an area of higher concentration of those molecules to an area of lower concentration. Osmosis.
What is the definition of diffusion in cells?
Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. If a molecule can pass freely through a cell membrane, it will cross the membrane by diffusion (Figure below).
What is diffusion in science class 9?
Diffusion- The mixing of a substance with another substance due to the motion or movement of its particles is called diffusion. It is one of the properties of materials. The diffusion of one substance into another substance goes on until a uniform mixture is formed.
