All substances pass eaxily through the cee mem brane it is true for false?
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
Materials pass through the cell membrane, which acts as a barrier between the cell's interior and the external environment. The cell membrane is selectively permeable, allowing certain substances to pass through while blocking others.
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.
Small, non-polar molecules like oxygen, carbon dioxide, and water can easily pass through a cell membrane.
Dead molecules
The cell membrane, or plasma membrane, regulates the passage of materials into and out of cells through selective permeability. This means that only certain substances are allowed to pass through the membrane, while others are blocked or actively transported. This selective permeability helps maintain the internal environment of the cell and allows for proper function and communication with the external environment.
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
It doesn't! it just lets some materials that are useful for the cells into the membrane and others out, through diffusion.
