water
Small non polar molecules such as O2 or CO2 can easily diffuse through the cell membrane. Small polar molecules like water can also diffuse through the membrane, but less easily and more rarely.
The lungs is one place (oxygen carbon dioxide exchange), but the intestines, skin and kidneys are also tissues where there is an exchange between the environment and the circulation.
Liquid or gas
Water and Oxygen
Oxygen
Water
Water, sodium, potassium, glucose all diffuse in and out of the cell.
Isobutane
osmosis
water moves out. when water diffuses out of the cell, the cell shrinks, that is Hypertonic solution.
when salt water is added to an elodea leaf and all the chloroplasts within the cell moves to the outside of the cell or to the center of the cell. It balances the water A red blood cell is placed in fresh water. There are more free water molecules outside the plasma membrane then inside the cell, so osmosis occurs- water diffuses through the blood cell (causing it to swell and burst). the movement of water from an area of lesser concentration to one of greater concentration Also when you soak rice the starch from the rice goes into the water causing the Change of color

moving randomly
The cell needs food and water so it diffuses it to maintain health.
No, molecules do not have cell, rather a cell have molecules in it.
Isobutane
Water diffuses across their cell membranes
the outer most part of the cell where items diffuse into the cell, and waste diffuses out of the cell to be disposed.
