SAMPLE DESCRIPTIVE LAB REPORT Examination of Protozoan Cultures to Determine Cellular Structure and Motion Pattern Abstract Protozoans are unicellular eukaryotes with either plant- or animal-like characteristics. Through careful observation‚ we analyzed various protozoan cultures in order to identify characteristics associated with cell structure and movement of these one-celled organisms. We found that Protists exhibit certain characteristics that allow them to be categorized into different groups
Premium Eukaryote Protist Organelle
Protozoans (from Greek πρῶτον proton "first" and ζῷα zoa "animals"; singular protozoon) are microorganisms classified as unicellular eukaryotes.[1] While there is no exact definition of the term "protozoan"‚ most scientists use the word to refer to a unicellular heterotrophic protist‚ such as an amoeba or a cilipoopate. The term algae is used for microorganisms that photosynthesize. However‚ the distinction between protozoa and algae is often vague. For example‚ the alga Dinobryon has chloroplasts

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Kaur Pure Cultures Lab 1/31/13 Introduction : Pure cultures are made of only one type of organisms and can be used to study their properties. A method used to isolate pure cultures is making a steak-plate‚ which is a dilution process in which culture is spread over an agar plate in a certain manner. Using a loop rod‚ culture was taken from the tube and dragged across area 1 several time‚of the agar. The agar was then turned 90º‚ and the loop was flamed and cooled. Taking some culture from area

Lab report Introduction This mechanical testing is demonstrated the relationship between stain and stress for a certain material while it undergoes a tension force. And define the type of facture of them‚ which are two metallic‚ copper and low carbon steel and two polymeric‚ acrylic and acetone. Background Stress-strain curves show the response of material to an applied stress. It’s depend on the strain rate‚ temperature‚ and environmental conditions. They allow important information such

Introduction The purpose of this project was to detect which organism we had in our unknown mixed culture tube by running a series of experiments to detect which specific Gram negative organism we had. To detect your gram positive from the mixed culture was given as extra credit points also. A Gram stain was performed and isolation streak plate in order to isolate and observe the unknown organism. Before the series of test‚ a dichotomous key had to be written up in order to know what steps

Culture Key Concept in Cultural Anthropology Defining Culture • Everything humans perceive‚ know‚ think‚ value and feel is learned through participating in a cultural system • Human potential can only be realized within the structure of human culture and through growing up in close contact with other humans Scope of Culture • Things that strike as “natural” or “normal” or “common sense” or “human nature” or “instinctive” are often cultural • Mother/infant bond “human nature”

The prediction for this lab‚ is that the unwashed lettuce and the opened milk will have the most bacteria growth. All results are meticulous within the expectations of the lab report. II. Purpose The principle of this experiment is to have a thorough perceptive of: • Culture washed and unwashed lettuce on agar plate. • Culture fresh and opened milk with
