What are the distinguishing visual characteristics that differentiate yeast from bacteria when observed under a microscope?
Yeast cells are larger and have a more complex structure compared to bacteria. Yeast cells are typically round or oval in shape, while bacteria are usually smaller and have various shapes such as rods, spheres, or spirals. Additionally, yeast cells have a defined nucleus and organelles, while bacteria lack these structures.

What are the distinguishing visual characteristics that differentiate bacteria from yeast when observed under a microscope?
Bacteria are typically smaller and have a simpler, rod-shaped or spherical structure, while yeast are larger and have a more complex, oval-shaped structure with a distinct nucleus.
What type of organisms are usually observed with light microscope?
Organisms such as bacteria, yeast, algae, fungi, and small protozoa are typically observed with a light microscope due to their size and transparency. These organisms can be magnified to see their cellular structures and characteristics.
Which type of microscope was used to discover bacteria?
The microscope used to discover bacteria was the light microscope, specifically the compound microscope. Anton van Leeuwenhoek, a Dutch scientist, first observed bacteria through a simple microscope he created in the late 1600s.
How are acid fast stains used in the laboratory to detect certain types of bacteria?
Acid-fast stains are used in the lab to detect bacteria that have a waxy outer layer, like Mycobacterium tuberculosis. These stains help differentiate these bacteria from others by making them appear a distinctive color under a microscope.
What type of microscope is used to examine bacteria?
A light microscope is commonly used to examine bacteria. However, an electron microscope can also be used for higher magnification and resolution to observe bacteria in more detail.

What are the three types of bacteria?
1) Cocci 2) Bacilli 3) Spirilli

How do you examine live bacteria microscopically?
To examine live bacteria microscopically, a drop of the bacterial culture is placed on a microscope slide and covered with a coverslip. The slide is then observed under a light microscope at high magnification to see the bacteria in their natural, living state. Additional techniques like phase contrast or dark-field microscopy can also be used to enhance the visibility of the bacteria.
How can a microscope determine if the specimen is a living thing?
In a microscope some microorganisms may be checked if they are living or not e.g. Euglena , Paramecium etc. can easily be checked but Bacteria can't be checked , there are other methods for checking them .
Which type of microscope was used to discover bacteria?
The microscope used to discover bacteria was the light microscope, specifically the compound microscope. Anton van Leeuwenhoek, a Dutch scientist, first observed bacteria through a simple microscope he created in the late 1600s.
Bacteria can only be seen with?
Bacteria can only be seen with the aid of a microscope, as they are typically very small and not visible to the naked eye. A compound light microscope or an electron microscope is commonly used to observe and study bacteria.
What does role morphology play in distinguishing among species of bacteria?
Based on morphology of bacteria, bacteria can classified as one of three group of coccus, bacillus, or spirillum. A coccus is a sphere. A bacillus is a rod-shaped bacterium. A spirillum is a long cell with one or more curves or coils.
What kind of microscope do you use to see bacteria?
electric microscope

Why is bactriea a micro-organismns?
Bacteria(plural) are microorganisms because they can't be seen without a microscope unless they form colonies But,to study the morphology and other characteristics of the bacteria one needs a microscopic view.
What type of microscope is used to examine bacteria?
A light microscope is commonly used to examine bacteria. However, an electron microscope can also be used for higher magnification and resolution to observe bacteria in more detail.
