Elodea Test Lab Report

After conducting the trials for each beaker and each bag my hypothesis of each of the trials were correct. Every outcome I predicted occurred to each beaker and each bag. Beakers 1 and 2 decreased in mass while beaker 3 stayed constant. Beaker 4 actually increased in mass as well. Bags 1 and 2 increased in mass while bag 3 stayed the same. Bag 4 resulted in a decrease in mass. The results I got from this experiment do support what I predicted before the trials.

Above you can see a specimen of an Elodea leaf with a drop of aquarium water. I have labeled the cell wall, cell membrane, cytoplasm, and the chloroplast. If you look closely the cell membrane and the cytoplasm are really close to the cell wall. The cell wall is outer layer maintaining the cells shape while the cell membrane and cytoplasm are located on the inside of the cell wall.
After putting one drop of the hypertonic medium on the slide I noticed a change. It seems as if the chloroplasts have joined together and are inside of a circular figure. The figure is quite big and there are large amounts of them located throughout the walls of the cell. The cytoplasm color still stayed the same at green and this was what I was expecting to occur with a hypertonic medium. You can see how the chloroplasts are even more concentrated and with a small amount of space. The results slightly support my hypothesis in that the chloroplasts were way concentrated in a small amount of
