It is better for the cell if most molecules are prevented from entering.
It avoids the entry of unnecessary substances into cell.It is important in protection too.
Cell membrane is a living , thin, delicate, elastic. it is about 7 nm thick. so this structure of cell membrane helps it with being permeable.
Yard is to fence as cell is to membrane. Just like a fence surrounds a yard and allows certain objects in and out, a membrane surrounds the cell and only allows specific nutrients inside of it.
The permeability of the cell membrane controls which substances may pass in or out of the cell.
Which statements describe the cell membrane? Check all that apply. It only allows certain materials to leave the cell. It allows all materials to leave the cell. It only allows certain materials to enter the cell. It allows all materials to enter the cell. It helps the cell get rid of waste. It brings waste into the cell for storage.
The answer is the Cell MembraneThe answer is the Cell Membrane

The permeability of the cell membrane controls which substances may pass in or out of the cell.
The cell membrane acts as the barrier and transport proteins present in the membrane, such as globular proteins, transport molecules across cell membranes.
Yes, it is selective about the compounds and molecules it allows across the membrane.
diffusion; across a partially permeable membrane, down a ceoncentration gradient

Why must you do this. WHY
Facilitated Diffusion
The answer is the Cell MembraneThe answer is the Cell Membrane
The cell membrane allows substances in and out of the cell and is a crucial part of homeostasis
