“Diffusion is the process of movement of molecules from a region of higher concentration to a region of lower concentration.” Diffusion in Plants. Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells.

What is meant by diffusion?
Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration. Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things – it is how substances move in and out of cells.
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 simple diffusion in plants?
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.
What is diffusion and example?
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. Fast Facts. Related Content.
What is diffusion in geography?
In geography, the term diffusion refers to the spread of people, things, ideas, cultural practices, disease, technology, weather, and other factors from place to place. The three main types of this phenomenon are expansion diffusion, stimulus diffusion, and relocation diffusion.
What is diffusion biology example?
Examples of diffusion in living organisms Oxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood. carbon dioxide moves down a concentration gradient from the blood to the air in the alveoli.
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.
What is diffusion in your own words?
Diffusion is defined as a spontaneous net movement of particles down their concentration gradient or in other words from an area with greater concentration to the area with lower concentration without using any energy.
What is diffusion give two examples?
Perfume is sprayed in one part of a room, yet soon it diffuses so that you can smell it everywhere. A drop of food coloring diffuses throughout the water in a glass so that, eventually, the entire glass will be colored. Water diffuses into cooking noodles, making them bigger and softer.
What is significance of diffusion?
Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products.
What causes diffusion?
The kinetic energy of the molecules results in random motion, causing diffusion. It is the random motion of the molecules that causes them to move from an area of high concentration to an area with a lower concentration. Diffusion will continue until the concentration gradient has been eliminated.
What is plant respiration?
The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called ” aerobic respiration “.
What is diffusion in biology class 10?
“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”
What is an example of diffusion in plants?
In order to carry out photosynthesis a plant requires carbon dioxide. On the underside of leaves there are small holes known as stomata, carbon dioxide diffuse into the leaves via these. Leaves produce oxygen and water vapour and these in turn diffuse out via the stomata.
What is diffusion kid definition?
Kids Definition of diffusion 1: the act of spreading or allowing to spread freely. 2: the mixing of particles of liquids or gases so that they move from a region of high concentration to one of lower concentration.
