This is unique to each cell. Some particles are small enough to diffuse freely in most cells. Other particles require varying types of transport mechanisms to cross the cell membrane. If it is a substance the cell either needs to take in or get rid of, there are proteins and other mechanisms to accomplish this. There are even actions of the cell in order to export or import substances.
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.
The degree in which materials are able to flow freely through a cells membrane is known as?
study island : permibility
Why do solid lack property of diffusion?
Solids have tightly packed particles that vibrate in fixed positions, limiting their ability to move around and diffuse. Diffusion requires particles to be able to move freely and spread out, which is not easily achievable in solid materials due to their fixed structure.
What substance is able to move freely through a cell membrane because of the size of the molecule?
Small nonpolar molecules, such as oxygen and carbon dioxide, can move freely through a cell membrane due to their size and hydrophobic nature. The lipid bilayer of the membrane allows these molecules to pass through easily without the need for transport proteins. This passive diffusion occurs along the concentration gradient until equilibrium is reached.
How does the cell membrane support cells in getting needed nutrients?
Cell membranes have a number of ways that needed nutrients can pass through. The first and easiest way is by diffusion where certain particles are able to pass through the membrane directly where the are in short supply. Other particles, because they don't mix well with the lipids that make up the membrane can pass through certain protein channels in a process called facilitated diffusion. In a closely related process to diffusion where particles aren't able to cross the membrane but water can, osmosis takes place. Sometimes when cell need to move nutrients into already crowded areas they use energy in a process called active transport to kind force particles across the membrane where they don't want to go. A very special type of active transport called phagocytosis occurs when a cell wants to take in particles that are simply too large to pass through the membrane so the membrane actually stretches out and engulfs the particle in a vesicle where it can be dismantled into smaller components inside the cell. I hope that helps!

Which particles-starch or Lugol's-were able to cross the model cell membrane?
The Lugol's solution particles were able to cross the model cell membrane, while the starch particles were too large to pass through. Starch is a large molecule that cannot diffuse across the membrane, while Lugol's solution contains smaller molecules (iodine and iodide ions) that are able to pass through.

Why do small nonpolar molecules cross a membrane?
Small nonpolar molecules can cross a membrane easily because they are able to pass through the lipid bilayer of the membrane due to their size and lack of charge, allowing them to move freely across the membrane.

Why is a liquid able flow?
a liquid is able to flow because its freely moving particles allow liquid to flow from place to place
What allow electricity to flow easily?
Basically, the fact that there are charged particles that are able to move around freely.
What solids made of?
Particles. Just like liquids and gases. The difference between them is that solids have tighter packed particles that are less able to move freely
How do the particles move in liquids?
The particles in liquid move freely.

What three things can pass through a cell membrane or cell wall easily?
no., not all types of the molecules can not pass through the cell wall in few case some of the organelles can pass but if they ire in the favor on the cell wall. and if they do passe then they do pass from the cytoplasm of the cell., it is generally appeared in the plant cell.
