According to text book and handout Microorganisms, are minute living things that individually are usually too small to be seen with unaided eye. Ubiquity means to be present everywhere. Microbiologist believed that microorganisms are everywhere and have tried to prove it. In this experimenting this lab, we had an experiment on ubiquity. This lab wanted to prove the microbiologist that on this planet has microbes everywhere. To understand more about ubiquity experiment, an important terms need to be explained.
Agar is gelatinous- complex polysaccharide obtained from red algae. An agar plate is a Petri dish that has an agar and nutrients used to culture microorganisms. Also, agar can be expand by adding other nutrients such as glucose and other …show more content…
In bacteria, cell wall is determined what types of bacteria are. Cell wall of bacteria are called peptidoglycan and composed of complex carbohydrate and protein. Additionally, there are three types of bacteria Gram Positive, Gram Negative and Acid fast. Most bacteria on agar plate will be cream, white, or yellow with circular shape.
Yeast are single celled microorganisms and eukaryotic organisms. They are belongs to the kingdom of Fungi. Typically, they have a round- white shape, but it may appear in football …show more content…
1. Form is the basic shape of colony.
2. Elevation is an appearance of colony when looking from the side way.
3. Margin is any important characteristic growth on the colony.
4. Surface is exterior characteristic of colony.
5. Opacity is an ability transparent in a colony.
6. Chromogenesis is the color of the colony. http://www.sciencebuddies.org/science-fair-projects/project_ideas/MicroBio_Interpreting_Plates.shtml
In a lab experiment, it needs to have two types of controls that is negative control and positive control. These controls will make the end result of experiment without any bias. A positive control is an experimental setup which receive test or treatment, so we are expected what might happens in it. On the other hand, negative control is an experimental set up which is not received any test or treatment, it is being observed its nature state.
Purpose
The purpose of this experiment to identify and differentiate between different types, size, and shape of microorganisms; bacteria, mold, and yeast by using agar to culture and observed these microorganisms and how they can be found on different types of surfaces. And determine weather or microbe are
