Microscopic Organism Lab

Amoeba
Power: x400

Eukaryotic, Heterotrophic
This cell is unique because it has psuedopods that find the food to consume, and digest it by performing phagocytosis. Its cell membrane looks think like jelly.

Euglena
Power: x400

Eukaryotic, Autotrophic
This cell is unique because it could be both heterotrophic and autotrophic, and it is neither a plant or an animal. It has a flagellum that looks like a string.
Bacteria Cells:General Shapes
Power: x400

Prokaryotic, Autotrophic
This cell is unique because there are 3 main shapes(labelled above). Bacteria cells have no organelles and for this reason, considerably smaller than most cells.
Plant: Lingustrum
Power: x400
Eukaryotic, Autotrophic
This cell is unique because it is made up of 50 different species, as it is a genus of plants. The cross section shown above is green with chloroplasts, and has an apparent vein.
Cyanobacteria (Blue green Algae)
Power: x400

Prokaryotic, Autotrophic
This cell is unique because it is a prokaryotic autotroph, because it is a photosynthetic bacteria. There are no chloroplasts found in the cell.
Animal Cell: Skeletal Muscle Tissue
Power: x400
Eukaryotic, Heterotrophic
This cell is unique because it is multinucleate. There are also pink and purple colored muscle fiber, composed of bands called stritations. 
Plant Cell: Spirogyra
Power: x400

Eukaryotic, Autotrophic
This cell is unique because it is  long and skinny with a cell wall made of carbohydrates(cellulose and pectin). Although the central vacoule takes up most of the space, there is a nucleus in the center of the cell, and chlorplasts line the outer edge after they are pushed out by the vacoule.

Summary:
   In this lab, we observed and identified the different parts of microscopic cells. In the muscle cell we found the nucleus, muscle fibers and stritations. In the lingustrum we found the chloroplasts, epidermis cell, and the vein. In the spirogyra we found the cell wall, the chloroplast, and cytoplasm. In the bacteria, we were able to identify the coccus, bacillus, and spirillum. In the cyanobacteria, we found one single cell. The euglena had a nucleus, chloroplasts, and flagellum. The amoeba contained a nucleus, cell membrane, and psuedopods. The autotrophs, or producers were mostly plant and bacteria cells, some with chloroplasts that made them green. The heterotrophs were consumer cells and contained nuclei. The eukaryotes all had a nucleus, and they contained many different cells and organelles, while the prokaryotes had no nuclei, and contained no organelles.
