Diffusion - Definition, Examples and Types | Biology Dictionary
2017年4月27日 · 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.
Diffusion - Definition, Causes, Significance, Examples - Biology …
2024年11月11日 · 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
What is Diffusion in Biology? - Types and Examples of Diffusion
2024年3月28日 · What is Diffusion in Biology? 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 - Definition and Examples - Biology Online Dictionary
2022年3月18日 · 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.
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 How Does it Occur (with Diagram)
2023年11月21日 · Diffusion is defined as the movement of atoms, ions, and molecules from a region of high concentration to a region of low concentration, or ‘down their concentration gradient ’. The word ‘diffusion’ is derived from the Latin word, ‘diffundere’, meaning ‘to spread out’.
2.13: Diffusion - Biology LibreTexts
Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. The difference in the concentrations of the molecules in the two areas is called the concentration gradient .
Diffusion - Biology Simple
2024年3月6日 · 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 - Wikipedia
The concept of diffusion is widely used in many fields, including physics (particle diffusion), chemistry, biology, sociology, economics, statistics, data science, and finance (diffusion of people, ideas, data and price values). The central idea of diffusion, however, is common to all of these: a substance or collection undergoing diffusion ...
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.
