1. Describe the major differences between gram positive and gram negative bacteria cell walls. The gram negative bacteria cell wall is a thin peptidoglycan layer and an outer cell membrane with a lipopolysaccharide layer. The gram positive bacteria cell wall is a single thick peptidoglycan layer. This wall forms in a mesh like formation of three layers of alternating material. 2. From the procedure that you have carried out‚do you feel that the Gram positive stain is a simple procedure? No‚

Laboratory(TFMB1001) Report Experiment Tittle Gram stain Experiment Date 24October2014 Submission Date 31October2014 Students Name Tittle Gram stain. Objectives Aim of this experiment is to differentiate between the two major categories of bacteria ‚ gram positive and gram negative. Through this experiment‚ gram staining skills develop. More understanding the types and morphology of bacteria. Expected experimental result‚ Escherichia coli (E.coli ) is a negative gram bacteria which stain pink colour

All four Peanuts characters take different approaches to their assignment. Though most finish successfully‚ they all encounter problems on the way that influence the direction their report takes. All begin by saying “Homework‚ yuck.” None of them enjoy the Lucy attempts to write whatever comes to mind with some nonsense included. More focused on the word limit‚ she attempts to write several fillers with whatever comes to her mind. Though what most of what she writes makes sense‚ she ends up pausing

physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions. The transfer of energy can occur in a variety of ways‚ among them conduction‚radiation‚ and convection. The SI unit of heat is the joule. Heat can be measured by calorimeter‚ or determined indirectly by calculations based on other quantities‚ relying for instance on the first law of thermodynamics. In calorimeter‚ the concepts of latent heat and of sensible heat are used. Latent heat produces changes of

Gram Staining Gram Staining is a method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative). Gram Staining is a way to separate one large group of bacteria into two. Crystal violet is used to dye the cells‚ which is the primary stain. Those that retain the color are grouped as Gram-positive‚ and those that do not retain the color are grouped as Gram-negative. Many of the Gram-negative bacteria are pathogenic‚ making this process useful for detecting infections

Gram Staining of Bacteria Since bacteria is really small microbiologist use stains to help them see bacteria more clearly under the microscope. Many of the stains they use color the bacteria cells directly and are called direct stains. Bacteria cells have a slightly negative charge while direct stains have a slightly positive charge that helps the stain bin to the bacteria. The strength of the binding from the stains depends on the make-up of the cell wall itself. Gram staining is the most helpful
