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 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 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

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.
