How does solute concentration affect the movement of water across a biological membrane?
What is a passive transport? A passive transport is the movement of something across the membrane with no energy. There are 4 main passive transports. There is diffusion, osmosis, Facilitated Diffusion, and Filtration. Diffusion were molecules will spread out evenly into empty space. Osmosis is the movement of water across a membrane. Passive transport happens when you get Pruned Fingers. Cholera is also made by osmosis. Cholera is found in our intestines and it reverses the intestinal cells.
As said in the last paragraph osmosis is the movement of water across the membrane. Well osmosis breaks down into 3 groups itself. Isotonic, is where the concentration …show more content…

Work in pairs. You will eventually share your data with other members of the class.
Step #2:
Obtain two decalcified eggs, provided by your teacher. Gently blot them on a paper towel and determine the mass of each, using correct procedure (use weighting paper or a container on the balance). Record the initial mass of each egg in the spaces provided in Data Tables 1 and 2.
Step #3:
Place one egg in a beaker. Fill this beaker with distilled water to just cover the egg. See Figure 1. Note the appearance of the water at this time and record your observation in Data Table 3. CAUTION: Be careful to avoid breaking glassware.
Step #4:
Place the other egg in a beaker. Pour syrup into the beaker to just cover the egg. Note the appearance of the syrup at this time and record your observation in Data Table 3.
Step #5:
Using the marker, label one plastic spoon water and the other spoon syrup. After 24 hours have elapsed, use the correctly labeled plastic spoon to remove each egg from its beaker. Carefully blot the egg with a paper towel and determine the mass of the egg that was immersed in water. Record in Data Table 2 the mass of the egg that was immersed in
