To begin‚ I had to find out how mold happens. Mold happens when bread is left out in moist areas. Mold grows because it seeks moisture warmth and food. Mold forms because in dust there are tiny micro-organisms and fungi along with it. The type of fungi found in air is called a spore‚ and it does the same thing as the dandelion seeds when you blow them in the air. A spore will float around until it lands on something and if that something is food‚ that spore will germinate and grow into a fungus

BACTERIA. CLASSIFICATION Bacteria are extremely small and some can be just seen with the naked human eye. They are much smaller than eukaryotic cells but are still very complex despite their size. .the cell is surrounded by a cell membrane that enclosees the bacteria cell. They are single celled organisms. Bacteria are prokaryotic cells and therefore do not have a nucleus and do not have a lot of organelles like: mitochondria‚ chloroplasts‚ and other organelles that are usually found in eukaryotic

SCOPE OF MICROBIOLOGY: What is Microbiology? | � Microbiology is the study of microorganisms� Microorganisms‚ roughly‚ are living things that are too small to be seen with the naked eye� Microorganisms cannot be distinguished phylogenetically from �macroorganisms� (see variety of microorganisms‚ below)� Microbiology is more a collection of techniques: aseptic technique‚ pure culture technique‚ microscopic observation of whole organisms‚ etc.� Microbiologists

Exercise 8-B Differential Staining Gram Staining and Acid Fast Staining Introduction: Differential Staining‚ one which facilitates differentiation of various elements in a specimen is a general term that can refer to a number of specific processes. Using multiple stains can better differentiate between different microorganisms or cellular components of a single organism. Gram’s Stain is a widely used method of staining bacteria as an aid to their identification. It was originally devised by Hans
