The cell membrane is like the skin of the cell. It keeps foreign bodies out of the cell, allows the "good guys" in, and serves as a cushion for the organelles.

Why is membrane transport vital for normal cell functions?
Without a membrane transport system, a cell wouldn't be able to get rid of various toxins or take in vital nutrients. The cell takes in nutrients, such as glucose and oxygen; it keeps certain enzymes from leaving so the cell can survive. Also, it releases wastes such as lactic acids and carbon dioxide that would kill the cell. Thus, the cell membrane plays a vital role of regulating the substances that enter and exit the cell.
What regulates passage of materials into and out of cells?
The cell membrane controls movement of materials in and out of the cell.
Which cell structure controls what enters and leaves the cell?
The selective permeability of the cell membrane
What cell structures are made primarily from phospholipids?
cell membrane
What controls entry into and out of the cell?
Cell Membrane
What cell membrane does in the cell?
It allows in things that are vital to carry on life in the cell.
Does the elodea plant have a cell membrane?
All plants have a cell membrane as it is vital for survival since it regulates what enters and leaves our cells.
What cell is inside the cell wall?
In plant cells, which contain cell walls, there is a cell membrane inside the cell wall. Inside the membrane is the cytoplasm which holds all the cell's vital organelles.

Does the kingdom of animalia have a cell membrane?
Yes, the kingdom Animalia consists of multicellular organisms that have cell membranes. The cell membrane is a vital structure that surrounds animal cells, protecting them and regulating what substances can enter and leave the cell.
What does the cell membrane allow in?
The passage of certain substances through the membrane
Why movement across a membrane of a cell is vital for its survival?
Beacuse without it life would not be worth living!
What regulates passage of materials into and out of cells?
The cell membrane controls movement of materials in and out of the cell.
Which cell structure controls what enters and leaves the cell?
The selective permeability of the cell membrane
What cell structures are made primarily from phospholipids?
cell membrane
What does a cell membrane do for the cell?
The cell membrane controls what enters and leaves the cell, allowing the cell to absorb the oxygen and nutrients it needs to function. It also protects the cell from most dangerous chemicals. The cell membrane is vital because the cell needs to be able to control its oxygen and carbon dioxide levels.
What structure controls the passage of substances into and out of the cell?
cell membrane
