Gram Negative Petri Dishes
1,384 wordsAbstract/Summary: Changing our focus from the properties and functions that take place within the cell to the actual cell itself, we observed three specific bacterial types within this lab: Gram-positive bacteria, Gram-negative bacteria, and cyanobacteria. We closely observed the features of cyanobacteria and were able to differentiate them from other bacteria. We specifically observed gloeocapsa, merismopedia, anabaena, and oscillator. In addition to this we observed the different characteristi...

Gram Positive And Negative Bacteria
828 wordsGram Positive and Gram Negative Bacteria It is a well-known fact that bacterial cells, like plant cells, are surrounded by a cell wall. However, few people know that their cell walls are quite different. Bacterial cell walls are made up of polysaccharide chains linked to amino acids. At the same time, plant cell walls are made up of cellulose, which contains no amino acids. In the same way, bacterial cell walls themselves differ from one another. Scientists distinguish two types of bacteria cell...
