Lab Report Sample

In this lab I examined and drew different samples of slides and then categorized these slides into a logical evolutionary order. The first sample that most likely came first in the evolutionary order is the typical bacteria, which I viewed at a 1000 magnification. These bacteria can be found in the Eubacteria domain and kingdom. The bacteria in my sample were coccus, which means that the bacterium has a round shape, and this type of bacteria is one of the simplest forms of bacteria. These cells are also prokaryotic because they do not have a nucleus and they are heterotrophic because they do not produce their own food. These bacteria are unicellular, however they work together and interact with each other is groupings. The sample that probably …show more content…
This indicates that the blue green algae is more evolved because it takes advantage of the energy that comes from the sun and uses photosynthesis to create food for itself. Next would be the vorticella. Vorticella is in the Eukarya domain and the Protista kingdom, and it is autotrophic. The vorticella is a unicellular organism that usually anchors itself to small particles of material with its stalk but can also survive its own. The vorticella shows an evolutionary advancement because the vorticella is an organism that can organize itself to be with more complex organisms unlike the blue green algae that are only organized among them. This organism is also more advanced because the organism is eukaryotic, which means it has a nucleus. This is important because the DNA information in no longer just out anywhere in the cell, but now the DNA, that allows the cell to survive, is now in an enclosed membrane that can protect the genetic information and control the entire cell. The sample that comes next is the spirogyra vegetative. The spirogyra is in the Eukarya domain and is in the Protista
