Small, nonpolar molecules such as oxygen and carbon dioxide can pass freely through a plasma membrane. These molecules can diffuse directly through the lipid bilayer due to their size and hydrophobic nature. Additionally, small uncharged polar molecules like water can also cross the membrane, albeit at a slower rate, often facilitated by specific channels.
What else can I help you with?
What Substances that can freely dissolve through the plasma membrane are made of?
Substances that can freely dissolve through the plasma membrane are generally small and nonpolar molecules, such as oxygen, carbon dioxide, and ethanol. These molecules are able to pass through the lipid bilayer of the plasma membrane without requiring a specific transport protein.
What molecules can freely cross the plasma membrane?
Proteins, Carbohydrates, and Cholesterol. (Check out, 'fluid mosaic')
How do lipid or oil get through plasma cell membrane?
Lipids and oils are able to move through the plasma cell membrane via simple diffusion. The lipid bilayer structure of the membrane allows for the passive and selective movement of non-polar molecules, such as lipids and oils, without the need for energy input.
Oxygen crosses the plasma membrane by?
simple diffusion. Oxygen is a small, nonpolar molecule that can pass freely through the lipid bilayer of the plasma membrane. This process does not require energy and is driven by the concentration gradient of oxygen on either side of the membrane.
How does nutrients enter a cell?
The plasma membrane.
What does not freely diffuse through the plasma membrane?
glucose

What is made from lipids and diffuse freely into cells through the plasma membrane?
protiens
What is the semipermeable membrane?
The cytoplasm of a cell is surrounded by a cell membrane or plasma membrane. The membrane is said to be 'semi-permeable', in that it can either let a substance pass through freely, pass through to a limited extent or not pass through at all.the membrane is somewhat effective at letting fluids through
What is made from lipids and diffuse freely into cells through the plasma?
protiens
Is the cell membrane permeable to glycerol?
No. Permeability of glycerol through plasma membrane= (approx) 1.9 x 10^-9 m/sec Permeability of water through plasma membrane = 2.0 x 10^-6 m/sec
Can large polar molecules pass through the plasma membrane?
No, large polar molecules cannot pass through the plasma membrane.
What do you call the movement through the cell membrane?
permeation through the plasma membrane perhaps?

Where is glucose taken into cell?
through the plasma membrane
