Diffusion is the passive movement of substances from a region of higher concentration to a region of lower concentration. Diffusion of substances plays an important role in cellular transport in plants. Rate of diffusion is affected by concentration gradient, membrane permeability, temperature, and pressure. Diffusion takes place as long as there is a difference between the concentrations of a substance across a barrier. However, diffusion stops, when the concentrations of the substance on either side of the barrier become equal. The permeability of a membrane affects the rate of diffusion. Diffusion rate increases as membrane permeability increases. Changes in temperature and pressure values also affect the diffusion of substances. Pressure plays an important role in the diffusion of gases as gases diffuse from a region of higher partial pressure to a region of lower partial pressure.

There are several factors that affect the rate of diffusion, which is how fast particles move from an area of high concentration to low concentration.

One main factor is the temperature — higher temperatures give particles more energy, so they move faster.

Another is the concentration gradient — the bigger the difference in concentration between two areas, the faster the diffusion happens. Particle size also matters; smaller particles diffuse quicker than larger ones.

Surface area plays a role too — the larger the surface area, the faster diffusion can take place.

Lastly, the type of medium (like air, liquid, or solid) affects diffusion speed — it happens fastest in gases, slower in liquids, and slowest in solids.

The rate of diffusion depends on a few key factors.

First, temperature makes a big difference — when it’s warmer, particles move faster, so diffusion happens more quickly.

Then there's the concentration gradient, which is basically the difference between high and low concentrations; the bigger the difference, the faster diffusion occurs.

Molecule size is important too — smaller molecules move and spread out faster than larger ones. Also, if there’s a larger surface area, diffusion can happen more efficiently.

Lastly, the state of the medium matters — diffusion is quickest in gases, slower in liquids, and slowest in solids because of how tightly packed the particles are.

Several factors influence how fast diffusion happens.

One is temperature—when it’s higher, particles have more energy and move faster, speeding up diffusion.

Another important factor is the concentration gradient, which means the bigger the difference between concentrations on each side, the quicker diffusion takes place.

The size of the particles matters too because smaller particles can diffuse more easily than bigger ones.

Also, a larger surface area allows more particles to move at once, increasing the rate.

Finally, the medium through which diffusion happens makes a difference—diffusion is fastest in gases, slower in liquids, and slowest in solids.
