Introduction Cells are the building blocks of the diverse idea we call life, which means that they must be as diverse as life as well. Prokaryotic and Eukaryotic cells make up most of the life on this planet, and vary widely in function, while still sharing some similarities. Prokaryotic cells, although simpler and smaller, make up most life. A nucleoid region contains a loop of nucleic acids known as a DNA plasmid. Prokaryotic cells contain simplified ribosomes which free float in cytoplasm all bound by a cell membrane and wall. Eukaryotes, on the other hand, contain complex double membraned organelles, complex DNA (arranged on chromosomes), and a nucleus. Due to the efficiency required of the cell, it is significantly larger than prokaryotes,

Although it was difficult to see any organelles, the shape was very clear to see. However, based on previous knowledge, it can be estimated that each cell can have anywhere from 10-20 chloroplasts. When exposed to light, these chloroplasts were supposed to begin to show signs of cyclosis, however, the chloroplasts were very difficult to see and cyclosis was unable to be observed. Cyclosis, or the movement of chloroplasts, is generally uniform in rate and direction of movement. In comparison, plant cells are much larger than bacteria. At the same magnification, the elodea cells are much larger and easier to see than the lactobacillus cells. This increase in size is allowed because of the endomembrane system in eukaryotes like plants. The cell wall, composed of cellulose fibers, was the most visible part of the cell by …show more content…
When the potato cells were scraped off of the surface, the structure was disturbed, resulting in the oddly shaped cells observed. Iodine, a starch indicator, was added, resulting in a purple colored amyloplasts, where the cell’s starch is stored. No other structures were stained intensely because of the condensed location of the starch in the cell. Amyloplasts, like chloroplasts, are a type of plastid. Since other plastids were difficult to view, a conclusion on the comparative qualities of plastids observed cannot be drawn. However, according to the National Institutes of Health, amyloplasts and chloroplasts are very similar, sometimes even changing into one or another based on light availability. The size and shape are similar, as is the function.
Human epithelial cells were one of the more easily viewed cells. This animal cell was an organic shape, unlike the rigid walls of plant cells. Chloroplasts were not present in the cheek cells either. They did, however, both contain a defined nucleus, cell membranes, and cytoplasm. These cheek cells are thin because they did not appear 3 dimensional under the
