No, osmosis is the movement of water particles through a semi-permeable membrane, from a place where there is a high concentration of water, to where there is a lower concentration of water. It can be confusing, because when we talk about solutions we often refer to the concentration of the solute rather than the solvent.
For instance, if we have a cell containing cell sap with a high concentration of sugar, and a more dilute solution outside the cell, water will flow into the cell. If you think about the sugar, it might seem that particles are going to the more 'crowded' areas, but the important thing is the concentration of the molecules which are moving, i.e. the water molecules. A dilute solution of sugar has a higher concentration of water than a concentrated one.
Active transport is the mechanism by which particles are moved from areas of lower concentration to areas of higher concentration in a cell. This process requires energy to pump the particles across the cell membrane against their concentration gradient.
Particles diffuse due to random thermal motion, which is driven by temperature and concentration gradients. When there's a difference in concentration between two regions, particles move from areas of higher concentration to areas of lower concentration in an effort to achieve equilibrium. This movement occurs spontaneously, as particles collide and spread out, resulting in diffusion. Thus, it's not that particles "know" when to diffuse; rather, they naturally tend to move towards areas of lower concentration due to random motion and entropy.
The process that moves particles from areas of high concentration to areas of lower concentration is called diffusion. During diffusion, particles spread out to achieve an equilibrium, where their concentration is uniform throughout the space. This process occurs naturally and does not require energy input. If the movement involves a selectively permeable membrane, it may also be referred to as facilitated diffusion.
Passive transport that moves particles away from areas is called facilitated diffusion. This process uses transport proteins to help molecules or ions pass through the cell membrane, moving from areas of higher concentration to areas of lower concentration without using energy.
Diffusion
Active transport is the mechanism by which particles are moved from areas of lower concentration to areas of higher concentration in a cell. This process requires energy to pump the particles across the cell membrane against their concentration gradient.
Diffusion is the process that allows movement of gases and ions from areas of high concentration to low concentration. This process occurs passively, driven by the concentration gradient, and does not require energy input from the cell.
Particles will diffuse from areas of higher concentration to lower concentration to reach equilibrium. This process is driven by the random motion of particles. The direction of diffusion can be predicted by following the concentration gradient, where particles will move towards areas of lower concentration.
who even knows!
diffusion
the movement of particles from areas of greater concentration to area of lesser concentration.
diffusion
Particles moving from problem areas to less crowded areas are called diffusion. Diffusion is the process by which particles spread out and move from areas of high concentration to areas of low concentration to create equilibrium. This movement occurs due to the natural random motion of particles.
Down concentration gradients.
Particles diffuse due to random thermal motion, which is driven by temperature and concentration gradients. When there's a difference in concentration between two regions, particles move from areas of higher concentration to areas of lower concentration in an effort to achieve equilibrium. This movement occurs spontaneously, as particles collide and spread out, resulting in diffusion. Thus, it's not that particles "know" when to diffuse; rather, they naturally tend to move towards areas of lower concentration due to random motion and entropy.
This movement of particles is called diffusion, where particles tend to move from regions of higher concentration to regions of lower concentration until equilibrium is reached.
This is diffusion. No energy required, molecules do this just based on random molecular motion. Example: a drop of ink dropped into a beaker of water will "diffuse" until it is as spread out as possible.
