The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
What would happen if you had a cell in the water and molecules were in the cell and some were out the cell what would most likely happen after a period of time?

What kinds of molecules pass through a cell membrane most easily?
small and hyrdophobic molecules
Is diffusion of molecules across the cell membrane the most complex type of active?
No, diffusion of molecules across a cell membrane is a passive process, not active, and arguably the least complex.
What do you call molecules that carry out most cell function?
protiens
Is DNA a cell or not a cell?
DNA is a chemical compound. It forms the largest single molecules inside cells (and most viruses) and stores the information used to make and operate the cell.
What is the largest molecules in organisms?
The largest organic molecules are nucleic acids.

What does the cell wall help?
1) holds in the molecules that allow the cell to function (to be alive). 2) keeps out most foreign molecules. 3) "contains" transport molecules that move specific molecules in and out.

The process of homeostasis results in?
The cell keeps more molecules inside the membrane.The cell does not allow molecules to cross the membrane.The cell keeps most molecules outside the membrane.The cell keeps molecules balanced inside and out
What molecules form the double layer of cell membranes?
A double layer of phospholipids makes up most of your cell membranes
How do most molecules cross the cell membrane?
Diffusion or if the molecules are too large they go through the transport proteins.
What is meant by the statement that a Cell membrane is semipermeable?
This means that there are more facets to 'trans' membrane molecular movement than {merely} diffusion - which is the simplest. The smallest of molecules pass both ways unimpeded. Medium sized bio-molecules are permitted transit via facilitated diffusion; while the largest and most biologically active bio-molecules are selectively accepted or refused at any of a Myriad of Cell Membrane structures that are known [in short] as Cell Surface Receptors.
