What is the process of dissolved food passing through a cell membrane?
Diffusion
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What is it called when particles travel from an area of high concentration to an aera of low concentration?
Through passive transport
Would oxygen particles enter a cell through diffusion more likely than fat particles?
Yes, oxygen particles would enter a cell through diffusion more readily than fat particles due to their smaller size and higher solubility in the cell membrane. Fat particles are larger and less likely to pass through the cell membrane via simple diffusion.
What is the process by which tiny particles can pass through the cell membrane?
Small particles can pass through the cell membrane by simple diffusion. If the particles are water, the process is given a special name: osmosis.
What is the name for the diffusion of dissolved particles?
Selective permeability by the cell membrane-Ben
Why do dissolved particles on one side of the membrane result in the diffusion of water across the membrane?
Dissolved particles on one side of the membrane results in the diffusion of water across the membrane due to the need to have the same solution concentration on both sides of the membrane. Water will diffuse from a hypotonic solution to a hypertonic solution.
What is the process of dissolved food passing through a cell membrane?
Diffusion
Why do dissolved particles on one side of a membrane result in the diffusion of water across the membrane?
When one area has a higher concentration than another area substances move from the area of high concentration to the area of low concentration.
How is equilibrium related to diffusion and osmosis?
Equilibrium in diffusion and osmosis is reached when there is a balanced distribution of particles or solutes across a membrane, resulting in no net movement of particles. In diffusion, equilibrium is reached when there is an equal concentration of particles on both sides of the membrane. In osmosis, equilibrium is reached when the water concentration is the same on both sides of the membrane.

Particles moving across a cell membrane without using energy?
Diffusion and Osmosis
Would oxygen particles enter a cell through diffusion more likely than fat particles?
Yes, oxygen particles would enter a cell through diffusion more readily than fat particles due to their smaller size and higher solubility in the cell membrane. Fat particles are larger and less likely to pass through the cell membrane via simple diffusion.

What structure allow small particles to cross cell membrane?
Osmosis.
When particles are moves through a membrane from a region of high concentration to a region of low concentration?
Diffusion
