The amoeba is unique because it has pesudopods, whcih surround food and pull the food into the cytoplasm.

The amoeba has purple and blue pesudopods.

It is a eukaryotic cell, and it is heterotrophic. 

Power: 400x

The euglena is unique because there are dark circles inside the cell.

The euglena is green because it has chloroplasts.

It is a eukaryotic cell, and it is heterotrophic and autotrophic. 

Power: 400x

The cyanobacteria has no chloroplasts because it has no green pigments.

The cyanobacteria looks like blue links of sausage.

It is a prokaryotic cell, and it is autotrophic.

The bacteria cells is unique because it consits of cocci, bacilli, and spirillums.

The bacteria cell has many visible spirllum, which looks like a spiral twist.

It is a prokaryotic cell, and it is autotrophic.

The spirogyra is unique because it has visible spirals.

The spirogyra is green because it has chloroplasts.

It is a eukaryotic cell, and it is autotrophic.

The ligustrum is unique because it has long cells.

The ligustrum is green because it has chloroplasts.

It is a prokaryotic cell, and it is autotrophic.

The skeletal muscle tissue is unique because it has many nuclei.

This animal cell looks like blocks and strings.

It is a eukaryotic cell, and it is heterotrophic.
     In this lab, we asked the question what are the key features of autotrophs, heterotrophs, prokaryotes, eukaryotes, and protists. I examined seven different types of cells under a microscope. I found that the muscle cell, the euglena, and the amoeba all had a nucleus. I saw the nucleus of each cell under the microscope. This means that the muscle cell, the euglena, and the amoeba are all eukaryotic. The ligustrum, spirogyra, bacteria, and cyanobacteria did not have a nucleus. These cells are prokaryotic because they do not contain a nucleus. The ligustrum, spirogyra, and the euglena all had chloroplasts. They all had green color in them. Chloroplasts convert light energy from the Sun into sugars that can be used by the cells. 
Muscle cell: nucleus, one muscle fiber, striations

Ligustrum: chloroplasts, epidermis cell, vein

Spirogyra: cell wall, chloroplast, cytoplasm

Bacteria: coccus, bacillus, spirillum

Cyanobacteria: one single cell

Euglena: nucleus, chloroplast, flagellum

Amoeba: nucleus, cell membrane, pseupods 

     Autotrophs are producers. If the cell has chloroplasts, then it is an autotroph. Heterotrophs get their energy from eating autotrophs or other organisms. If a cell has no autotrophs, then it is a heterotroph. Eukaryotes have a nucleus, and prokaryotes do not have a nucleus.
