Diffusion - Definition, Examples and Types | Biology Dictionary
Oct 4, 2019 · Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration. The material that diffuses could be a solid, liquid or gas.
What Is Diffusion? - Definition, Types & Examples Of Diffusion
“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.” Read on to explore what is diffusion and the different types of diffusion.
Diffusion - Definition and Examples - Biology Online Dictionary
Mar 18, 2022 · To define diffusion in the biological context, imagine the ions, respiratory gases, glucose, or other particles that move randomly between the crowded and the less-crowded regions (fluids), often across a semi-permeable membrane.

Nov 11, 2024 · Diffusion is a critical process in biology, physics, and chemistry, where molecules move from an area of higher concentration to lower concentration. It happens in two primary ways: simple diffusion and facilitated diffusion. Here’s a breakdown of each type and their subcategories: 1. Simple Diffusion

Oct 17, 2024 · The net movement, as a result of the random motion of its molecules or ions, of a substance from a region of its higher concentration to a region of its lower concentration. Diffusion across the cell membrane. Diffusion Factors Table. Certain substances cannot diffuse through the phospholipid bilayer of cell membranes. These include:
Diffusion | Definition & Examples | Britannica
Dec 3, 2024 · 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? - Types and Examples of Diffusion
Mar 28, 2024 · Diffusion is the process of movement of solutes and molecules from a higher concentration to a lower concentration across the membrane. This process is caused by the intrinsic kinetic energy of particles, resulting in random motion.
Diffusion - Biology Simple
Mar 6, 2024 · Diffusion in biology is the movement of molecules from an area of higher concentration to an area of lower concentration. It is a passive process that helps maintain equilibrium in cells and allows for necessary substances to enter and exit cells.
Diffusion Explained – Types, Examples and Factors - Eduinput
May 4, 2023 · Diffusion is the movement of molecules from an area of high concentration to an area of low concentration, which is caused by their random motion. A common example is the scent of perfume spreading through a room as molecules disperse into the air. In chemistry, diffusion influences the rate of chemical reactions.
Define diffusion in biology. - CK-12 Foundation
In biology, diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration (see figure below). It is a passive process, meaning it does not require any energy input. This movement continues until the concentration of the molecules is equal throughout the system, a state known as equilibrium.
