All substances pass eaxily through the cee mem brane it is true for false?
Because their particles size is smaller than the pores size of cell membrane.
I think it might be water, sodium ions, and oxygen gas.
Phospholipids permit lipid-soluble materials to easily enter or leave the cell by diffusion through the cell membrane. Phospholipids form a bilayer or double layer which makes up most of the membrane.
The cell membrane
The plasma member is a selectively permeable membrane which allows the entry and exit of substances in and out of the cell through the process of diffusion.
Although the cell wall is tough, many materials, including water and oxygen, can pass through easily.
The endoplasmic reticulum are transport tubes made of membrane that move proteins and other materials through the cell, most likely sending them towards the Golgi apparatus/body.
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
Cell Membrane

The cells go through the cell's membrane

Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.The things that can easily move in and out of the cell through the membrane are gases, like oxygen and carbon dioxide, and water.
Dead molecules
Through proteins in the membrane.
the oil will float on the the water which wold illustrate the cell membrane because only certain materials can pass through it
It doesn't! it just lets some materials that are useful for the cells into the membrane and others out, through diffusion.
