Organism Lab

Euglena cell magnified at x400. It is unique because it has a flagellum. It is green and purple. It is eukaryotic and autotrophic.

Amoeba cell magnified at x400. It is unique because it has pseudopods, which consumes cells. It looks like jelly and is very colourful. It is eukaryotic and heterotrophic.

Cynobacteria magnified at 400. There no chloroplasts because it is a prokaryotic cell and is autotrophic. It has no nucleus and is green and blue. 

Bacteria cells magnified at x400. Bacteria can be shaped as coccus, bacillus, and spirilum. They are a lot smaller than the other cells. Thay are pink and purple. It is prokaryotic and autotrophic because no nucleus..

Spirogyra cell magnified at x400. It has a cell wall, cytoplasm, and nucleus it is like a strand. Looks like spirals and is blue green. It is eukaryotic and autotrophic.

Ligustrum cell magnified at 400. It is unique because it has veins. It is green and blue. Composed of many dots. It is eukaryotic and it is autotrophic.

Skeletal Muscle Tissue magnified at 400. It is unique because there are muscle fibers. It was pink/purple and had many strands of fiber. It is eukaryotic and heterotrophic.

   In this lab, we asked the question: what are the key features of autotrophs, heterotrophs, prokaryotes, and eukaryotes. We observed different samples of cells under the microscope to see the characteristics. Based on our observations, we could identify whether the cell was an autotroph or a heterotroph and whether the cell was an eukaryote or a prokaryote.  Autotrophs have a key characteristics of being plant cells and some bacteria. Because of this, they have chloroplasts ,vacoules ,and cell walls, unless they are bacteria. Heterotrophs are consumers, meaning they consume other cells to get their energy. Heterotrophs do not have vacoules, chloroplasts, and cell walls. For a cell to be an eukaryote, it must have a nucleus and a nuclei. While a eukaryote has a nucleus, prokaryotes do not have a nucleus and also have no organelles. Eukaryote cells are bacteria and other cells with no nucleus and no organelles. In conclusion, we learned about identifying cells as an autotroph or a heterotroph and whether the cell was an eukaryote or a prokaryote.
