What materials go in and out of an organism's cells through?
The cells go through the cell's membrane
When materials move passively by diffusion in what dirction do they go through the cell?
Materials move passively by diffusion from an area of higher concentration to an area of lower concentration, across the cell membrane. This process allows the substances to reach equilibrium within the cell.
What do most food and wastes that move into and out of a cell go through?
enzymes
What materials is used for respiration and is taken in from the air?
Oxygen is the material used for respiration and is taken in from the air during the process of breathing. Oxygen is essential for the production of energy in cells through aerobic respiration.
What membrane allows only some materials to move in and out of the cell?
The cell membrane, which is a lipid bilayer, will only allow some things in and allow others to go out of the cell.

Why can smaller cells exchange materials faster than larger cells?
Because the materials can go through the small cell faster

The cell membrane, which is a lipid bilayer, will only allow some things in and allow others to go out of the cell.
How do materials move through the cell membrane in facilitated diffusion?
In facilitated diffusion, materials move through the cell membrane with the help of protein channels or carriers. These proteins create a passageway or binding site for specific molecules or ions to pass through the membrane. The movement is passive and follows the concentration gradient, meaning that molecules move from an area of higher concentration to an area of lower concentration.
Why are cellular transport and cellular communication factors that limit cell size?
The cellular transport and cellular communication factor that limit the cell size because all the materials that go in and out of a cell must pass through the plasma membrane.
Why cell transport and cellular communicator factor that limit cell size?
The cellular transport and cellular communication factor that limit the cell size because all the materials that go in and out of a cell must pass through the plasma membrane.
Why might material need energy to move through the cell membrane?
Materials may need energy to move through the cell membrane against their concentration gradient, which is known as active transport. This process requires cellular energy to pump molecules or ions across the membrane. Without energy, the movement of materials across the cell membrane would rely solely on passive processes like diffusion, which may not be sufficient for maintaining proper cellular functions.
Name the 2 ways that materials can pass through the cell membrane?
Materials can pass through the cell membrane via passive transport, which includes diffusion and osmosis, where molecules move from areas of high concentration to low concentration without the use of energy. Active transport, on the other hand, requires energy and allows molecules to move against their concentration gradient, such as through protein pumps or vesicle transport.
