The conditions necessary for diffusion is firstly a semi permeable membrane, and a concentration gradient for the movement of molecules from higher concentration to lower concentration. The size of the molecules should be small enough to pass easily through the membrane.
Diffusion can take place in any substance, cause diffusion means the mixture of gases . In a perfume shop diffusion takes place
Molecules move from an area from where there is a high concentration to an area where there is a low concentration. This occurs until equilibrium is reach. After equilibrium is reached, diffusion still occurs. (but in "equal trade") Diffusion is caused by the random movements of molecules.
Diffusion (passive transport) needs no energy to take place, and therefore no need for transport or carrier protiens. Active transport uses carrier protiens, as the cell needs to work against a concentration gradient. This requires energy. Diffusion can take place outside of cells Active transport can't take place outside of cells.
Facilitated diffusion is a passive transport process where molecules move across a cell membrane with the help of specific carrier proteins. These carrier proteins are present in the membrane and assist in the movement of molecules like sugars and amino acids down their concentration gradient. Facilitated diffusion occurs in the lipid bilayer of the cell membrane.
Capillaries are the tiny blood vessels where exchange of nutrients, gases, and waste products occurs between the blood and body tissues through the process of diffusion. They have thin walls that allow for efficient exchange of substances.
yes
There must be areas of different concentration.
diffusion takes place in the alveoli
Diffusion can take place in any substance, cause diffusion means the mixture of gases . In a perfume shop diffusion takes place
P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.
if the temp is higher then diffusion take place faster
China,china,china............
stomach,intestine
Cytoplasm
It is simpie diffusion through body surface
Diffusion occurs in the leaf to facilitate the movement of gases such as carbon dioxide and oxygen. These gases diffuse in and out of the leaf through small openings called stomata, allowing for photosynthesis and respiration processes to take place effectively. This exchange of gases helps the leaf to obtain the necessary substances for energy production and to release waste products.
Faster diffusion will take place if the surroundings are warmer. Increase in temperature means an increase in molecules' speed (kinetic energy).
