The process that occurs when a physical pressure pushes materials through a barrier is called?
Osmosis is the movement of water across the membrane, while diffusion is the movement of solids across a membrane Diffusion ordinarily does not require a membrane.The movement of particles of a substance by their own kinetic energy from their higher concentration to lower concentration is called diffusion.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What does the passive in passive transport mean?
Passive Transport is the movement of molecules down a concentration gradient from a region of high concentration to a region of low concentration until equilibrium is reached. Some examples are diffusion and osmosis. Basically, it's a movement of molecules across a membrane that doesn't require energy (ATP)
What is the differece between passive and active transport?
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell. ACTIVE TRANSPORT REQUIRES ENERGY. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. PASSIVE TRANSPORT REQUIRES NO ENERGY.
If a chemist wants to study dissfusion should a semipermeable membrane be used?
Diffusion is essentially the movement of solute molecules from a region of higher concentration to a region of lower concentration. A semi permeable membrane need not be used to study this phenomenon
What does osmosis require?
Osmosis is the movement of particles from a high concentration to a low concentration accross a partially permeable membrane.
What is the similarities between osmosis and diffusion?
They both follow the concentration gradient i.e. require no energy for the process to occur. Diffusion is the movement of particles from an area of higher concentration to lower concentration. See Brownian motion. Osmosis is the movement of WATER particles across a semi-permeable membrane from an area of higher concentration to the lower concentration in the effort to reduce the solute concentration.
How are diffusion and filtration alike?
Both move down concentration gradient through a partially permeable membrane, and both do not require energy. Diffusion involves the movement of particles or solute from an area of high concentration to an area of low concentration. Osmosis is the movement of water from where it is in high concentration to where it is in low concentration.

What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What is the name for the movement of water access the plasma membrane?
The movement of water across the plasma membrane is called osmosis. Water moves from where it is in higher concentration to where it is in lower concentration. Osmosis is a type of passive transport and does not require any energy expenditure by the cell.
Does osmosis require protein?
Nope! Osmosis is simply the movement of H2O over a membrane from high concentration to low concentration. It's a form of passive diffusion!
What is A cell moving particles with the use of energy is called?
Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
Process of diffusion?
Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, driven by the natural tendency of particles to distribute themselves evenly. This process occurs spontaneously and does not require energy input. It is essential for nutrient and waste exchange in cells.
What types of diffusion do not require energy?
Diffusion does not require energy. Diffusion is that natural tendency of particles to move from an area of high concentration to an area of low concentratrion and therefore, it does not need energy to occur.
Describe the difference between diffusion and osmosis?
although both are the movement of particles from an area of high concentration to low, diffusion is the movement of many kinds of substances however osmosis refers to the diffusion of water particles only from an area of high water concentration to an area of low water concentration.
What does the passive in passive transport mean?
Passive Transport is the movement of molecules down a concentration gradient from a region of high concentration to a region of low concentration until equilibrium is reached. Some examples are diffusion and osmosis. Basically, it's a movement of molecules across a membrane that doesn't require energy (ATP)
