Q1 What is gram staining? How do the Gram-Positive and Negative bacteria look under a gram stain? Gram staining is a differential staining technique that differentiates between gram-negative and gram-positive groups by colouring these cells purple or pink.

Mitochondria (or related structures) are found in all eukaryotes (except the Oxymonad Monocercomonoides). Although commonly depicted as bean-like structures they form a highly dynamic network in the majority of cells where they constantly undergo fission and fusion.

There are three basic shapes of bacteria: coccus, bacillus, and spiral. Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus.

Flesh-eating bacteria typically enter the body through breaks in the skin, such as cuts, burns, insect bites, or as in Adams' unusual case, human bites. If left untreated, the infections can lead.

Identify the genera of bacteria that are acid-fast and two examples of diseases caused by these species. Differentiate the cell wall structures of acid-fast and non-acid fast bacteria. Successfully execute an acid-fast stain and interpret the results.

In this article we will discuss about the Structure of Bacterial Cell. Bacteria (sing. bacterium) are unicellular prokaryotic microorganisms which divide by binary fission. They do not possess nuclear membrane and the nucleus consists of a single chromosome of cir­cular double-stranded DNA helix (Fig. 1.1).

Even after symptoms pass, approximately 2–5% of cases become chronic carriers and inadvertently spread typhoid through ongoing faecal shedding of the bacteria and contamination. It is important for people being treated for typhoid fever to do the following: take prescribed antibiotics for the full prescribed course;

Living World & Classification of Microbes Q Bank - Answers Exercises 1. Use Whittaker’s method to classify bacteria, protozoa, fungi, algae, prokaryotic and eukaryotic microbes. 2. Complete the five kingdom method of classification using- living organism, prokaryotes, eukaryotes, multicellular, unicellular, protista, animals, plants, fungi. 3.

Give an example of a bacterium of high G+C and low G+C group commonly associated with each category Prokaryotes are identified as gram-positive if they have a multiple layer matrix of peptidoglycan forming the cell wall.

They are flagellated, aerobic bacteria, having a spirally twisted rod-like form; e.g., Treponema. Microorganisms: Friend and Foe Class 8 Extra Questions Higher Order Thinking Skills. Question 1. Unscramble the jumbled words underlined in the following statements (a) Curbossulite is an air-borne disease caused by a bacterium.

For example, staphylococcus aureus bacteria are found in spherical clusters. Clostridium bacteria are rod-like and singular. Though small, bacteria are powerful and complex.
