Answer:
In plants, the cell wall is full of small holes called plasmodesmata. If there were no cellular membrane all of the fluid in the cell (cytoplasm) would just leak out. The membrane also acts as a barrier to the outside world, controlling the influx of nutrients, hormones, chemicals and other substances the cell uses.
In animals, if there is no cell wall so the absence of a cellular membrane would make all animals a pile of goop on the ground.
Explanation: in other words its important because it protects it from harmful things
There's 2 in the first energy level
Which leaves 2 left to go in the second level
Btw the second level can normally hold a max of 8
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
