Osmosis and simple diffusion are not sufficient for the transport of all substances due to their nature. They only have the ability to transport substances which can pass through the cell membrane.
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.
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.
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.
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.
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.
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.
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.
Yes, osmosis and diffusion are both examples of passive 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.

Diffusion. With the need of energy, it would be called active transport.
Diffusion and osmosis are passive and do not require energy.
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.
