Carbon dioxide is a relatively small molecule, and can diffuse through semi-permeable membranes easily, providing that it moves down a higher concentration gradient.

Why cant polar molecules and ions diffuse across the cell membrane?
Ions cannot diffuse through a phospholipid bilayer because they are not able to dissolve in lipids, hence the phosphoLIPID bilayer . Also, since they have an electrical charge, they are repelled by the membrane.
Why do some materials easily pass through a cell membrane?
All substances pass eaxily through the cee mem brane it is true for false?
Why was Hawaii chosen as a site to measure carbon dioxide levels in the atmosphere?
- carbon dioxide is a green house gas - determinations of carbon dioxide in the atmosphere are important for the study of climate changes, especially for the evolution of temperatures - determinations of carbon dioxide in the atmosphere are also important for the study of seas/oceans acidity (and of course for marine biology) because CO2 is easily absorbed in water
Lipid-soluble materials enter and exit the cell via?
Phospholipids permit lipid-soluble materials to easily enter or leave the cell by diffusion through the cell membrane. Phospholipids form a bilayer or double layer which makes up most of the membrane.
Why is carbon dioxide not considered a an organic compound?
Carbon Dioxide could easily be described as an organic compound. As it based on carbon scientifically it is a organic compound. If you feel like being more on the philosophical side of science and use the definition that organic compounds are not man made, then carbon dioxide is still an organic compound as humans produce only a small amount of it.
What molecule is able to easily diffuse across the cell's membrane?
Carbon dioxide, oxygen and some nonpolar molecules diffuse easily.
What creates selective permebility of plasma membrane?
It is because of the make up of the membrane. Most of the bilayer is hydrophobic; therefore water or water-soluble molecules do not pass through easily. Other do pass through easily. A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.
What properties of carbon dioxide and oxygen allow them to easily cross a membrane?
i believe its their small size-- low atomic weight.
Oxygen and carbon dioxide pass back and forth between the alveoli and the blood through?
Oxygen and carbon dioxide easily pass back and forth between the alveoli and the blood through the capillaries.
What expands the most when heated hydrogen peroxide carbon dioxide or iron?
A gas as carbon dioxide is easily expanded by heating; hydrogen peroxide is decomposed.
Oxygen and carbon dioxide move easily through most areas of cell membranes because they are soluble in what?
lipids.
What are you considering when you referring to how easily materials can pass through membrane?
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
The nuclear membrane is allowing materials to pass through?
A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.The things that can easily move in and out of the cell through the membrane are gases, like oxygen and carbon dioxide, and water.
Is it true that carbon dioxide dissolves easily in water?
Yes, the dissolved carbon dioxide reacts chemically with the water making carbonic acid, allowing more carbon dioxide to dissolve.
What kind of molecules can easily pass through a cell membrane?
Small, Non-polar molecules. If the molecule is polar, it sticks to both sides of the membrane, and has to go through selective routes. The easiest to get through is the Non-polar (oxygen and carbon).
What is the gas put into soft drinks to make the bubbles?
The gas in fizzy drinks is carbon dioxide. When under pressure, carbon dioxide easily dissolves into water. It is a gas without color or odor.
How easily carbon dioxide can be converted to combustible gas?
You can't change the chemical properties of a compound without changing what the compound is. Carbon dioxide cannot become a combustible gas and still be carbon dioxide.
