Osmosis 4/13/13 MLT1 Lab 9 Performed at Home Microbial Growth There are three types of environments in which cells are located which include isotonic‚ hypotonic and hypertonic. In an isotonic environment‚ the amount of water and solute are the same both inside and outside of the cell. As water drifts into the a cell‚ the same amount flows out creating a balanced environment both inside and outside of the cell. When there is a high level of

to stain bacteria are basic dyes. The most common background stains are acidic dyes since they do not cross the cell wall/membrane particularly easily. A background stain is a stain used to stain everything other than the bacteria. The Gram stain is one of the oldest‚ most cost-efficient‚ yet most under-utilized‚ staining method used to identify bacteria. It consists of a basic dye (the primary stain crystal violet)‚ a mordant (Gram ’s iodine)‚ decolorizer (acetone:alcohol) and a counter stain (safranin)

Lab Report #1: Observing Bacteria Microbiology Abstract: This lab exercise familiarized the student with the use of a microscope by observing and identifying various different slides under the microscope. The student practiced observing the given slides under the 10x‚ 40x‚ and 100x (oil immersion) objective lenses‚ which allowed for the identification of the different organism’s shapes and sizes. Purpose: The aim of this exercise is to equip the student with the knowledge
