Diffusion, osmosis, and active transport are methods by which a cell can move molecules across its membrane. Diffusion is the passive movement of molecules from an area of high concentration to low concentration. Osmosis is the diffusion of water molecules across a selectively permeable membrane. Active transport requires energy to move molecules against their concentration gradient.

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.
Passive and active transport?
Active Transpot. -Pumps -Endocytosis -Exocytosis Passive Transport - Diffusion -osmosis -Facilitated Diffusion active requires energy passive doesnt. active against concentration gradient, passive along concentration gradient.
Are diffusion and osmosis two types of active transport?
No, diffusion and osmosis are passive transport processes that do not require energy input from the cell. Active transport, on the other hand, requires the cell to use energy to move molecules across the cell membrane against their concentration gradient.
What processes can take place in a root hair cell when oxygen is not available?
active transport and osmosis
what cell can diffusion osmosis and active transport deal with?
All types of cells, including prokaryotic and eukaryotic cells, can utilize diffusion, osmosis, and active transport to transport molecules across their membranes. These processes are essential for maintaining proper internal conditions within the cell and for communicating with the external environment.
Is diffusion and osmosis both active transport?
no they are passive transport
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
What is active transport in a plant?
a houseplant in dry soil is this process diffusion,osmosis,or active transport
Is diffusion an example of active transport or passive transport?
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
What are the types of movement through a membrane?
Osmosis, diffusion, facilitated diffusion, active transport
Is sugar osmosis or passive transport or active transport?
Sugar transport can occur through both passive transport, such as facilitated diffusion or simple diffusion, and active transport, such as primary or secondary active transport processes. Osmosis specifically refers to the movement of water across a semi-permeable membrane, so sugar transport itself is not osmosis.
Are diffusion and osmosis types active transport?
No. (Active xport would be in the opposite direction.)
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.
In what ways do molecules move?
it moves by diffusion, osmosis and active transport
What is the difference between active transport and osmosis?
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.

Three ways stuff moves in and out of cells?
diffusion, osmosis, active transport
