Are diffusion and osmosis types of active transport?
No, diffusion and osmosis are passive transport processes, not active transport. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration, while osmosis is the movement of water across a selectively permeable membrane. Active transport, on the other hand, requires energy and moves substances against their concentration gradient.
Diffusion and osmosis are types of active transport true or false?
False. Diffusion and osmosis are both types of passive transport, where molecules move from an area of higher concentration to an area of lower concentration without the need for energy input.
How do diffusion osmosis facilitated diffusion and active transport diffusion differ?
Diffusion is the movement of molecules from an area of greater concentration to an area of lesser concentration. e.g. Exchange of gases in the lungs or body tissues. Osmosis is the diffusion of water through a semi-permeable membrane from an area of low solute to an area of high solute concentration. Faciliated diffusion is the passive transport of molecules down a concentration gradient. It is simply diffusion that involves a protein to make diffusion happen more easily across a cell membrane. Active transport is the moving of substances across the cell membrane using the cell's energy. Molecules are moved against a concentration gradient, i.e they move from an area of lesser concentration to an area of greater concentration. Tlhis is done by a carrier molecules which gets its energy from ATP.
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
A special form of diffusion that applies only to water?
Osmosis is the special form of diffusion that applies only to water. It is the movement of water molecules from an area of high concentration to an area of low concentration across a semipermeable membrane.
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
What are some reasons osmosis and diffusion are not sufficient reasons for the transport of all substances to pass in and out of cells?
Some substances are too large to pass through the cell membrane via osmosis or diffusion. Additionally, some substances require specific carrier proteins or energy input to be transported across the membrane. Finally, certain substances may need to move against their concentration gradient, which cannot be achieved through osmosis or diffusion alone.
Osmosis and diffusion are examples of passive transport?
Yes, osmosis and diffusion are both examples of passive transport.
Are diffusion and osmosis types of active transport?
No, diffusion and osmosis are passive transport processes, not active transport. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration, while osmosis is the movement of water across a selectively permeable membrane. Active transport, on the other hand, requires energy and moves substances against their concentration gradient.
What is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active transport.
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
How does diffusion from active transport?
Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.
Is diffusion and osmosis both active transport?
no they are passive transport

What are three parts of passive transport?
diffusion, facilitated diffusion, and osmosis
