its about the concentration of water in cells

Yes.  When you eat potato chips, the salt concentration in your blood increases.  This means that there is more stuff in your blood than there is in your cells.  This results in your blood basically being a hypertonic solution which results in a net movement of water out of your cells.  This can be felt most easily when a high salt concentration draws the water out of the cells that line your mouth (these cells are used to a very moist environment of fairly pure water, so a sudden increase in salinity has a rather profound effect).

This is not a pure biology question. Should be bio-chemistry.

the more solute...the higher the solute concentration which lowers the water potential (concentration of water)

Yes, osmotically refers to the water and salt ion gradients inside and outside a cell's, or any selectively permeable, membrane. There are three states of osmotic condition. Isotonic = similar inside and outside.  Hypertonic where there is more salt ions outside fo the cell.  Water osmotically diffuses out of the cell.  This leads to cellular creanation Finally, hypotonic where there is more salt ions inside the cell  Water osmotically diffuses into the cell.  This is osmosis leading to cytolysis.

flask x- There will be a net influx of water to the blood cells because there a higher concentration of water outside the blood cells, the cell will expand.\nflask y- no net gain or loss of water to the cell. The cells are in equalibrium with the solution. Water will flow in and out, but at an equal rate so there is no net gain. \nflask z- there is a net efflux of water out of the cells  because there is a higher concentration of water in the cell than in the solution. as a result the cell will shrink.

They have a semi-permiable membrane.  Water will always seek to have equal number of solutes on either side of the membrane.  Therefore if the red blood cell suddenly has an increased amount of fluid rushing in (to try to equilibrate the solute concentration) then the cell will burst.

Most living things, including people, are about 80% water.

These answers are taken drectly from the listed link.  \n\nIn animal cells, being in a hypertonic environment results in crenation, where the shape of the cell becomes distorted and wrinkled as water leaves the cell. \n\nPlants thrive in hypotonic environments. Their cells have rigid cell walls that prevent bursting. In fact, the pressure of the cytoplasm against the cell wall keeps the plant from wilting and losing its shape.

prokaryotic cells are not bounded by membranes while eukaryotic cells are bounded by membranes.

The easiest way to understand osmosis is to think about a bottle of strong perfume.  When you take the lid off the molecules spread out filling the room slowly with smell.  Molecules move from an area of high concentration to an area of low concentration.  (that is your answer, I believe)  Another way to understand it is to drop food coloring into a large bowl of water.  It will slowly spread throughout the bowl.

the cell dividing force lol. theres no such force. it's a spontaneous occurence

Osmosis in potatoes. \nPut pieces of potato in different conc. of glucose solution and look at the changes.

Cells have different shape to allow them to work better. For example, the alveoli cells are flat and big in surface, these features helps in gas exchange.

I assume this is based on the principle of Osmosis. I would like a bit more data before answering further.

The minerals and salts in the water dehydrates the body the more water you drink.

Normally the particles (let us call them solutes for now) move from where they are more in concentration to where there are less solute particles in solution. This is just diffusion. This is some kind of standard stuff ALL THINGS MOVE FROM HEIGHTS to DEPTHS!! no more energy is required for this.\n\nBUT there are many more things in life which need to go against this principle and this is where the cell needs to spend energy ATP may be.. So when some particles are actively transported what it means is that energy is spent to do something against the concentration gradient. If it wants to bring more K+ ions into a cell which already has heaps when compared to the outside it needs to spend energy, There are many reasons why it may want to do it.. ... may be it wants to accumulate stuff for later (store glucose)..\n\n ..\nhope that helps,,,
