Endocytosis and exocytosis?

Cell membrane selectively allows substances to enter and exit the cell through protein channels and pumps, a function that cannot be accurately modeled by a plastic bag. Plastic bags lack the dynamic regulation and control mechanisms of a cell membrane to actively transport molecules and maintain cellular homeostasis.

Is a membrane an organ or tissue?
Skin is a membrane because it keeps that which is within it contained. There was a cell then more cells which made tissues, so there were tissues and more tissues and this made an organ, when more then one organ works together to perform a function it is then a body system.
All cells contain a membrane?
Yes, all cells are surrounded by a cell membrane, also known as the plasma membrane, which controls what enters and exits the cell. The cell membrane is made up of a phospholipid bilayer with embedded proteins that help maintain the cell's structure and function.
Why is it important that a membrane separate the cellular regions on either side of an ATP synthase molecule in order for the protein to perform its function?
A membrane separation is crucial for ATP synthase to establish a proton gradient across the membrane. This gradient serves as the driving force for ATP synthesis as protons flow through the ATP synthase from high to low concentration. Without this separation, the necessary proton gradient cannot be generated.
Do choloroplasts function outside the cell?
It is a cell organelle. It cannot function outside.
Can roots wrapped in plastic bag asborb water?
No. Roots wrapped in plastic bag cannot absorb water.
What is a major function of the cell membrane?
The cell membrane controls which substances can and cannot enter a cell.
Why do cells need to use transport proteins to function?
Carbohydrates cannot pass directly through the cell membrane. some important molecules are too large to pass through the cell membrane
Who is you the people modeled after?
I'm not sure what you are trying to ask so I cannot provide an accurate answer to your question.
What cannot be made without plastic?
Things that do not have long chain moleculesin general cannot be made to plastic. Buteven milk & starch can be made into plastic.

Are plastic plants good for cats?
Cats cannot eat plastic.
How do you repair the shift key and cap lock function on windows 8 laptop?
Unless you take it to a computer shop most cannot be repaired. Especially if its the contact part. If it's just the plastic piece then you may be able to replace it from an old parts keyboard. Most laptop keyboards are seperate from the main board and is just a thin membrane type board and can be replaced whole.
Can plastic be digested?
i have discovered that you cannot digest plastic. As me and my friend experimented it and ate different size plastic buttons 4 weeks ago and they have not digested because the enzymes in our intestine cannot break down the strong bonds in plastic.
Why should I recycle plastic?
because ,plastic cannot dispose so they get polluted the envirorment .
How the member function can be undefined?
You cannot undefine a member function.
What is an impermeable solute?
An impermeable solute is a substance that cannot pass through a semipermeable membrane, such as a cell membrane. This means that the solute is unable to diffuse or move across the membrane and remains on one side of the membrane.
All cells contain a membrane?
Yes, all cells are surrounded by a cell membrane, also known as the plasma membrane, which controls what enters and exits the cell. The cell membrane is made up of a phospholipid bilayer with embedded proteins that help maintain the cell's structure and function.
