diffusion biology essay exam
This does not mean that there is no movement through the membrane, however, just that the movement is such that the concentrations stay the same. D) facilitated diffusion and regular diffusion require the same amount of energy if someone is admitted to a hospital for severe dehydration, what type of solution should the doctor administer through the iv drip to make him or her feel better? Question 1. In science-y terms, diffusion is the passive movement of molecules from an area where they are highly concentrated to areas where they are less concentrated lets break that down by looking at the example of adding milk to your coffee.
These bags were placed in a beaker with 250ml of water and 4 drops of lugols solution. If the plant had not been watered, its cytoplasm would have continued to shrink to the point where the cell membrane pulled away from the cell wall, causing it to die. The distribution of the milk and all the molecules its made up of is equal and evenly spaced there is not one side or one corner of the box that has a greater concentration of milk than the other.
As you already know, they dont just stay as this weird ball of milk in the middle of your coffee, but they spread out until the amount of milk is even throughout your cup, and there is once again equilibrium. This setup was left to stand for 30 minutes, and both the bag and the beaker were tested for glucose. This too is a passive mechanism that requires no energy. In times of war, people would often salt the fields of their enemies, ensuring that the environment would be too hypertonic for any crops to be able to grow.

Wolfson51404ap biology, per 78chapter 42-gas exchange and circulationi. Because of this, animal cells burst much more easily than plant cells and can be destroyed through a large influx of water. The fish in the ocean, for example, are always in hypertonic solutions, but, seeing as they are always in water, they are able to immediately replace all of the osmotic water loss by continually drinking large amounts and excreting the salt.
If the plant had not been watered, its cytoplasm would have continued to shrink to the point where the cell membrane pulled away from the cell wall, causing it to die. Their roles in the transportation of materials across a semipermeable membrane, as well as the relationship between solute concentration and the movement of water, were part of the experiments that helped show their functions. In science-y terms, diffusion is the passive movement of molecules from an area where they are highly concentrated to areas where they are less concentrated lets break that down by looking at the example of adding milk to your coffee.
The first experiment, showing diffusion, required dialysis bags with dextrose in it, which had to be tested for glucose. Now generally, the purpose of having a barrier is either to keep stuff in, or to keep stuff out, but, its very rare that youll want to keep everything in or out.

The seawater around them always has higher concentrations of solutes than their cells do.AP BIOLOGY ESSAY QUESTIONS
