The names of these processes are diffusion or osmosis (osmosis is the diffusion of water molecules only). These are both passive and so do not require any energy. However, facilitated diffusion using carrier and channel proteins is also a passive process of moving substances across the cell membrane.
What else can I help you with?
What are 2 ways that substances across the cell membrane without using energy?
simple diffusion, facilitated diffusion, and osmosis (water)
What is the movement of substances without the use of energy by the cell?
Passive transport.
How do you use passive transport in a sentence?
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
In facilitated diffusion do molecules move down concentration gradient?
Without using the cell's energy
How do materials get into and out of the cell?
Through proteins in the membrane.
What are 2 ways that substances across the cell membrane without using energy?

Substances that move across a cell membrane without using energy?
Passive transport is the movement of substances across a cell membrane without the use of energy. This process includes simple diffusion, facilitated diffusion, and osmosis. These mechanisms rely on the concentration gradient to drive the movement of molecules.
What is the movement of substances without the use of energy by the cell?
Passive transport.
What is the movement of substances through a cell membrane without the use of cell energy?
passive transport
Cell must expend energy to transport substances using?
Facilitated diffusion.
What cell must expend energy to transport substances using?
Facilitated diffusion
What cell is the process by which materials move without using the cell's energy?
"diffusion"
Which term refers to the production of energy by a cell without using energy?
Fermentation.
A phase that provides energy for a cell without using oxygen?
Fermentation.
What refers to the production of energy by a cell without using oxygen?
Fermentation
What is the process by which materials move without using the cell energy?
"diffusion"
When substances move through a cell membrane by diffusion the cell uses a lot of energy to move those substances. Is this true or false?
False. Diffusion is a passive process that does not require energy input from the cell. Substances move down their concentration gradient from an area of high concentration to an area of low concentration. The cell membrane facilitates this movement without the need for energy.
