The movement of water across the plasma membrane is called osmosis. It occurs in response to concentration differences of solutes on either side of the membrane.
Movement across a membrane that does require energy is called active transport.
It is called passive diffusion.
No, primary transport involves the active movement of ions or molecules across a membrane against their concentration gradient, using energy typically derived from ATP. In contrast, the passive movement of large particles across the membrane is known as facilitated diffusion, which does not require energy and occurs through specific transport proteins. Thus, primary transport is an active process, while passive movement relies on concentration gradients.
Osmosis is the movement of water particles from an area of high concentration to an area of low concentration, across a semi-permeable membrane.
The movement is random, but there is a net movement from regions where there are lots of particles to ones where there are fewer particles.
The movement of water across the plasma membrane is called osmosis. It occurs in response to concentration differences of solutes on either side of the membrane.
A selectively permeable membrane allows water molecules to pass through but restricts the movement of larger solute particles like NaCl. In osmosis, water will move from a dilute solution to a concentrated solution through the membrane, causing a net movement of water without the movement of NaCl.
Diffusion is the process where molecules or particles move from an area of higher concentration to an area of lower concentration, resulting in the equal distribution of the substances. It plays a crucial role in various biological and physical processes, such as the exchange of gases in the lungs and the movement of nutrients into cells.
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.
Movement across a membrane that does require energy is called active transport.
A selectively permeable membrane is required for osmosis. This membrane allows the passage of water molecules but restricts the movement of solute particles based on their size and charge.
Diffusion is the movement of particles from an area of high concentration to an area of low concentration, while convection involves the transfer of heat through the movement of the fluid itself. In diffusion, particles move randomly, while in convection, the fluid moves in a specific direction due to temperature differences.
Diffusion is the movement of particles from an area of high concentration to an area of low concentration. This process occurs naturally and does not require external energy to drive it. It is an important mechanism for the transport of substances across cell membranes.
Osmosis is the movement of water 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. While both processes involve the movement of molecules, osmosis specifically refers to the movement of water molecules.
... is called "facilitated diffusion".
It is called passive diffusion.
