Basic dyes have positively charged chromophore; thus, there target of binding affinity is the specimen or the microorganism which has a negatively charged cell wall. Through this, basic dyes can penetrate and making it an efficient stain for microorganisms.

∙ 9y agoBasic dyes are used to stain bacteria because most bacteria is negatively charged, so positively charged basic dyes stick to bacteria walls. Basic dyes include crystal violet, methylene blue, safranin, malachite green.

∙ 9y agoBasic dyes stain bacterial cells due to their positive charges. There positive charges will bind electrostatically to negatively charged molecules.

What do microbiologists use microscopes for?
they study things called microbes that can only be seen with a microscope.
What can you gram stain living cells and look at the living cells under the microscope?
yes, but only with certain stains because some stains are toxic to live organisms.
Whats organelles are visible when methylene blue stains a tomato cell?
When methylene blue stains a tomato cell, it stains both the nucleus and the cytoplasm of the eukaryotic cells. These are the most important organelles of a plant.?æ
What do you call a person who studies germs or microbes?
Microbiologists specialize in studying microorganisms, but other biologists can study them to a lesser extent as part of their fields.
What is supra vital stains?
methylene blue and crystal violet, supravital stains are essential to identify Heinz bodies in G6PD deficiency patients. There are more but I do know another is brilliant cresyl. Supravital stains stain living cells. It also stains many other types of inclusions along with identifying Hemoglobin H, which is found in alpha thalassemia.
Who are the biologists who study cells?
Microbiologists
Why do people use stains when studying cells?
I don`t know. need your help
What do microbiologists use while they are working in the lab?
Microbiologists use many job specific tools to complete their investigation. Most importantly , a high end electron microscope with proper mounting wares are a essential.
What do microbiologists use microscopes for?
they study things called microbes that can only be seen with a microscope.
What can you gram stain living cells and look at the living cells under the microscope?
yes, but only with certain stains because some stains are toxic to live organisms.
How can microbiologists help third world countries?
For countries that have diseases, microorganisms are usually the culprits. That's where microbiologists step in. Microbiologists know a lot about diseases, so they can save the day! :D
What is microbiologists?
The branch of biology dealing with the structure, function, uses, and modes of existence of microscopic organisms is microbiologists.
Why are stains needed in Biology?
Stains are mainly used to differentiate and demarcate various minute organelles in the cells. Different parts of the cells can be distinctly stained to give a clear-cut picture of the study material.
Why are scientists who study the structure and function of cells called microbiologists?
Scientists who study the structure and function of cells are called microbiologists because the cells are very tiny and cannot be seen with the naked eye, but with a microscope. Microbiology describes the study of microscopic organisms - microorganisms - and their effects. A microorganism is a life-form too small to be observed with the naked eye - without using a microscope. The word 'microbiologist' is formed from 'micro' (very small) and 'logy' (the study or science or theory of something).
When testing microaerophils some microbiologists prefer to use a semisolid nitrate medium that contains a small amount of agar why is this done?
Microbiologists testing microaerophils prefer to use a semisolid nitrate medium that contains a small amount of agar to get more accurate results. This is also done to speed up the results.
Whats organelles are visible when methylene blue stains a tomato cell?
When methylene blue stains a tomato cell, it stains both the nucleus and the cytoplasm of the eukaryotic cells. These are the most important organelles of a plant.?æ
Why is microbiologist important?
Microbiologists study life processes that occur on the cellular level. This can mean the diagnosis and treatment of diseases caused by bacteria and viruses. It can also include studying the microscopic changes in plant and animal cells -- these can affect the ways that cells work, or how they affect other cells.
