What controls the direction of water movement during osmosis?
According to the Oxford English Dictionary, osmosis is defined as "a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one" (OED 2013). The greater mass present in the higher concentrated solution of the solvent causes the water molecule to pass through the sempermeable membrane until the water concentration of water with concentrated solution are balanced on both sides.
What is the difference between diffusuion and omosis?
Diffusion is the spreading out of a substance from a region where it is in higher concentration to one where it is in lower concentration. Osmosis is the special case of diffusion where the process takes place through a semi-permeable membrane, i.e. one which allows only some substances through it.
Movement of molecules from high high to low concentration?
This process is called diffusion. Diffusion occurs spontaneously in order to establish equilibrium, where the concentration of molecules is the same throughout a system. This movement is driven by the natural tendency of molecules to move from areas of high concentration to areas of low concentration.
Does oxygen enter a cell by diffusion or osmosis?
Oxygen enters a cell by diffusion, which is the movement of molecules from an area of higher concentration to an area of lower concentration. Osmosis, on the other hand, is the movement of water molecules across a selectively permeable membrane.
How do diffusion and osmosis share similarities in their mechanisms of movement across cell membranes?
Diffusion and osmosis are both passive processes that involve the movement of molecules across a cell membrane from an area of higher concentration to an area of lower concentration. In both processes, no energy is required for the movement of molecules.
What moves during diffusion?
Particles, cells, and molecules move from areas of higher to lower concentrated areas.
How osmosis and diffusion are alike?
Answerdiffusion- movement of molecules from higher proportion to lower proportionosmosis - movement of water molecules from a more CONCENTRATED solution to less concentrated solution
Is diffusion of water is called osmosis?
Yes, osmosis is defined as the net movement of water molecules from an area where they are highly concentrated to an area where they are less concentrated across a semi-permeable membrane such as a cell surface membrane.
If a bottle of ammonia is spilled in the basement and it's molecules spread to areas where the molecules are less concentrated so that you begin to smell it upstairs what has happened?
The ammonia molecules have diffused from an area of high concentration (the spill in the basement) to an area of low concentration (upstairs), allowing you to smell it. This movement of molecules from an area of higher concentration to an area of lower concentration is known as diffusion.
How would you compare and contrast osmosis and diffusion?
Osmosis is the movement of water molecules across a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration, while diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. Both processes involve the movement of molecules from an area of higher concentration to an area of lower concentration, but osmosis specifically refers to the movement of water molecules.
When a solution as a greater concentration particles?
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. This is due to the random movement of the molecules.
What is the spread of molecules in an area?
The spread of molecules in an area refers to how dispersed or concentrated the molecules are within that space. This distribution can be influenced by factors such as temperature, pressure, and the nature of the molecules themselves. In gases, molecules tend to be more spread out due to higher energy and movement, while in solids, they are more tightly packed. This concept is essential in understanding diffusion, concentration gradients, and various physical and chemical processes.
How does the movement of molecules in warm objects compare with the movement of molecules in cooler objects?
In warm objects, molecules move faster and have higher kinetic energy compared to molecules in cooler objects, which move more slowly with lower kinetic energy. This increased movement in warm objects leads to higher temperatures and faster chemical reactions.
What is the movement of molecules from areas of lower concentrations to regions of higher concentrations?
Diffusion
What is diffusion and how does it relate to the movement of material into and out of the cell?
diffusion is the kinetic movement of molecules from higher concentration to lower concentration.
What is the difference and similarities between osmosis and simple diffusion?
Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration. Simple diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. The main similarity is that both processes involve the movement of molecules across a membrane, but osmosis specifically refers to the movement of water molecules.
Movement of molecules along an imaginary slope usually from higher to lower concentrations?
Diffusion.
