The rate of diffusion through a semipermeable membrane will be lowest when?
The rate of diffusion through a semipermeable membrane will be lowest when temperatures are low. Lower temperatures decrease the energy of the molecules, which in turn decreases the rate of diffusion.
Where and when does osmosis occur?
Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher solute concentration until there is an equal concentration of fluid on both sides of the membrane .
What is diffusion rate proportional to?
rate of diffusion depends on the concentration gradient, surface area, distance over which diffusion takes place, size and nature of the diffusing molecule.
What is osmosis a type of?
Diffusion. Osmosis is the diffusion of water across a membrane.Osmosis is a special type of diffusion. It is the movement of water molecules only from a solution of higher water potential to a solution of lower water potential across a selectively permeable membrane.The characters in bold indicate the specificity of osmosis as compared to diffusion.(Biology, chemistry) diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal
What structure is the statement below most likely referring to A large glucose molecule requires facilitated diffusion but an oxygen molecule does not?
A large glucose molecule requires facilitated diffusion but an oxygen molecule does not is a semipermeable membrane.
Which affects the rate of diffusion through a semipermeable membrane?
steeper concentration gradients, higher temperatures and size of the molecule diffusing
The rate of diffusion through a semipermeable membrane will be lowest when?
The rate of diffusion through a semipermeable membrane will be lowest when temperatures are low. Lower temperatures decrease the energy of the molecules, which in turn decreases the rate of diffusion.
Is osmosis a form of diffusion?
Yes. Osmosis is a special case of diffusion - in involves just water diffusing across a semipermeable membranes - like in cell membranes.
What is diffusing in science?
Diffusion is a net transport of molecules from a region of higher concentration to one of lower concentration by random molecular motion.
What term descries the diffusion of water through a semipermeable membrane down a concentration gradient?
Osmosis!
What term describes the diffusion of the water through a semipermeable membrane down a concentration gradient?
Osmosis is the diffusion of water molecules down a concentration gradient through a semi-permeable membrane
How do cells use the process of osmosis and diffusion to take in nutrients and to get rid of wastes?
== == Diffusion is: the movement of particles from regions of higher concentration to regions of lower concentration. Osmosis is: the diffusion of water through a semipermeable membrane.
Can you have diffusion without osmosis?
Osmosis is the movement of water molecules across a semipermeable membrane from a region of higher concentration to a region of lower concentration. Diffusion is the movement of any molecules from a region of higher concentration to a region of lower concentration. so yes it is possible to have diffusion without osmosis.
How would diffusion differ from osmosis?
Osmosis is the net movement of water molecules across a semipermeable membrane from a region of a lower concentration to a higher concentration. Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration down a concentration gradient
What is essential for diffusion?
A- A Concentration Gradient B- A Selectively Permeable Membrane C- A Source of Energy D- A Protein The Answer Is (A) Diffusion can occur without a semipermeable membrane, as diffusion is simply movement of a substance from high to low concentration. A source of energy is needed only for active transport. Proteins are needed if the the particles transported are too big to pass the semipermeable membrane.
Does osmosis require a carrier?
NO. Osmosis( by definition) is the DIFFUSION of water from a high concentration gradient to a low concentration gradient across a semipermeable membrane. As diffusion is a form of passive transport, it doesnt require a carrier
What iprocess occurs as water moves from regions of higher concentration to lower across a semipermeable membrane?
Osmosis, which is the diffusion of water.
