yes a cell could remain alive but in that case FBGM
A membrane that allows some things to pass through it but not others. It can be to do with size of the molecule, electronic charge or other characteristics. Think of a sieve or colander as an example of the semi-permeable membrane and a mixture of sand and peas as the chemical mixture at one side of the membrane. The membrane will only allow the sand to pass through based on size. In cases such as this, larger molecules could pass through active transport channels and such that may be present on the membrane but these are energy-dependant whereas diffusion across a semi-permeable membrane is not.
Partially permeable , permeable , immpermeable .
Oxygen and water molecules can penetrate the cell membrane due to small gaps that are created by the lipid molecules. Lipid molecules overlap each other which makes the gaps. The oxygen and water molecules then enter in the gaps. The cell membrane in this case is semi permeable.
It is the preceedure in which an atom reproduces with the cell membrane creating a semi-universe in which time and space has no baring. Withing this new dimension species will then begin to grow until they have reached an evolution so great the find the abbility to leave there univers and attack ours, thus the creation of flies. i hope this has helped.Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.The definition contains three important statements:Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration.It does not matter too much which order you put these statements in. Nor does it matter if you write the definition as one sentence or three sentences. All that matters in your exam is that you make all three points when you explain what osmosis is.
Dialysis tubing is an impermeable membrane/containment vessel that is stratified with microscopic holes which restrict certain molecules or particles from diffusing through them. This leads dialysis tubing to serve as a selectively permeable membrane because it selectively prevents certain molecules from crossing the membrane based on the size of the molecules. (Typically water and glucose will diffuse through, whereas starch and potassium iodide will not.
the solubility theory of membrane permeability simply describes that a membrane can only be freely permeable to substances that can dissolve in it. this was the most basic theory posed to explain how substances passed through membranes of cells. another way of explaining this is that substances that can freely or passively diffuse across membranes when they have the same chemical or physical properties as the membrane.
plasma membrane is the outer most boundary of animal cell.it is chemically composed of lipids and proteins.it is selectively permeable allow certain materials to move in and out.fluid mosaic modle explain its structure.

Because it is a differentially permeable membrane so water can fit through but no other large molecules can. it is a passive process. :)
The fact that cell membranes are semi-permiable creates openings for the substances to enter.
do you go to UTAS? that is not an answer how is this going to help people ????

The model used to explain the components and properties of the plasma membrane is called the fluid mosaic.

it has dissolved substances in it
