Examples of molecules that can diffuse into a cell include oxygen, carbon dioxide, water, and small uncharged molecules like ethanol. These molecules can passively cross the cell membrane through processes such as simple diffusion or facilitated diffusion.
Small non polar molecules such as O2 or CO2 can easily diffuse through the cell membrane. Small polar molecules like water can also diffuse through the membrane, but less easily and more rarely.
The lungs is one place (oxygen carbon dioxide exchange), but the intestines, skin and kidneys are also tissues where there is an exchange between the environment and the circulation.

What is an example of molecules that diffuses out of a cell?
Examples of molecules that can diffuse out of a cell include oxygen, carbon dioxide, and water. These molecules can move across the cell membrane from an area of higher concentration inside the cell to an area of lower concentration outside the cell through the process of diffusion.
The passively diffuses oxygen and carbon dioxide in and out of the cell. cell wall plasma membrane nucleus protoplasm?
The plasma membrane is responsible for the passive diffusion of oxygen and carbon dioxide into and out of the cell. It regulates the movement of molecules in and out of the cell, allowing for gas exchange.
What diffuses more easily into a cell Na or isobutane?
Isobutane diffuses more easily into a cell because it is a small nonpolar molecule that can pass through the cell membrane via simple diffusion. Sodium (Na) is a charged ion and cannot easily pass through the hydrophobic interior of the cell membrane without the assistance of specific transport proteins.
Water molecules spreading through a membrane with a change in cell size is an example of what?
This is an example of osmosis, a passive transport process where water molecules move across a selectively permeable membrane from an area of high concentration to an area of low concentration. The change in cell size occurs due to the movement of water to balance the concentration of solutes inside and outside the cell.
In which process in which process this is so you molecules does the cell use a vesicles to move molecules into the cell?
cells

The water in a cell does what?
diffuses in and out of the cell
What function diffuses water molecules?
Osmosis

What is it called when iodine diffuses out of a cell?
Osmosis
What goes through the cell?
Nonpolar molecules (example: lipids) Small polar molecules such as water
Why does a cell diffuse items into the cell?
The cell needs food and water so it diffuses it to maintain health.
How do unicellular get water?
Water diffuses across their cell membranes
What is a cell plasma membrane?
the outer most part of the cell where items diffuse into the cell, and waste diffuses out of the cell to be disposed.
Does molecules have cell?
No, molecules do not have cell, rather a cell have molecules in it.
What is example of diffusion?
Tape a piece of wax paper over the window and it diffuses (spreads) the light. In the body: Oxygen molecules diffuse across cell membranes into cells, and carbon dioxide molecules diffuse out. Both compounds cross the phospholipid bilayer. In a non-living system: Place a small lump of sugar in a cup of tea (or just water). The sugar dissolves, then diffuses throughout the liquid. To see diffusion happening, use not sugar but a small crystal of potassium permanganate in water. The color will gradually disperse through the water.
When water diffuses into a plant cell and builds pressure?
tugor pressure
