Active transport is the movement of particles across a cell membrane against the concentration gradient with the help of energy. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, and osmosis is the movement of water molecules across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Diffusion and osmosis are forms of what?
Diffusion and osmosis are forms of passive transport, which is the movement of particles across a membrane without requiring energy input from the cell.
What incudes diffusion osmosis and facitated diffusion?
Diffusion is the movement of particles from an area of high concentration to low concentration. Osmosis is the specific type of diffusion where water molecules move through a selectively permeable membrane. Facilitated diffusion involves the movement of specific molecules across a membrane with the help of transport proteins.
Is making a cup of tea diffusion osmosis or active transport?
Making a cup of tea involves diffusion, which is the passive movement of particles from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water across a selectively permeable membrane, which is not directly involved in making tea. Active transport involves the movement of particles against a concentration gradient and requires energy, which is not typically needed for making tea.
What is diffusion and osmosis?
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. Osmosis is a specific type of diffusion involving the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.
How do osmosis and diffusion differ?
Osmosis is the movement of water molecules across a selectively permeable membrane, from an area of low solute concentration to an area of high solute concentration. Diffusion is the movement of particles from an area of high concentration to an area of low concentration, down the concentration gradient. Both processes are passive and do not require energy.
Diffusion and osmosis are forms of what?
Diffusion and osmosis are forms of passive transport, which is the movement of particles across a membrane without requiring energy input from the cell.
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 are the types of movement through a membrane?
Osmosis, diffusion, facilitated diffusion, active transport
What incudes diffusion osmosis and facitated diffusion?
Diffusion is the movement of particles from an area of high concentration to low concentration. Osmosis is the specific type of diffusion where water molecules move through a selectively permeable membrane. Facilitated diffusion involves the movement of specific molecules across a membrane with the help of transport proteins.
What two requirements distinguish osmosis from diffusion?
Osmosis involves the movement of water molecules across a semi-permeable membrane, while diffusion involves the movement of particles (e.g., ions, molecules) from an area of higher concentration to an area of lower concentration. The key requirements that distinguish osmosis from diffusion are the presence of a semi-permeable membrane and the movement of water molecules specifically in osmosis.
What are the types of particle transport how particles move into and out of the cell?
The types of particle transport mechanisms by which particles move into and out of the cell are diffusion, osmosis, and active transport.
Is making a cup of tea diffusion osmosis or active transport?
Making a cup of tea involves diffusion, which is the passive movement of particles from an area of high concentration to an area of low concentration. Osmosis is the diffusion of water across a selectively permeable membrane, which is not directly involved in making tea. Active transport involves the movement of particles against a concentration gradient and requires energy, which is not typically needed for making tea.
What are two forms of passive transport of a cell?
Two forms of passive transport in cells are simple diffusion and facilitated diffusion. Simple diffusion involves the movement of molecules across the cell membrane from an area of high concentration to an area of low concentration, while facilitated diffusion relies on the assistance of transport proteins to facilitate the movement of molecules across the membrane.
Diffusion and osmosis are forms of?
Diffusion and osmosis are forms of passive transport, where molecules move across a membrane without the need of energy. Diffusion involves the movement of particles from an area of high concentration to an area of low concentration, while osmosis specifically refers to the movement of water molecules across a selectively permeable membrane.
Is it active or passive transport or osmosis when particles move through protein doorways?
It is active transport if energy is required to move particles through protein doorways, such as in the case of pumps. It is passive transport if particles move through protein doorways without the need for energy, as in facilitated diffusion. Osmosis is the movement of water across a membrane, not particles through protein doorways.
What is the movement of particles in passive?
In passive transport, particles move across a membrane from an area of higher concentration to an area of lower concentration without the input of energy. This movement is driven by the concentration gradient and does not require the use of transport proteins. Examples include diffusion and osmosis.
Why the osmosis involves the movement of molecules via special transport protein?
facilitated diffusion
