How would you describe the morphology and arrangement of the cells in your stained preparations?
Bacterial cells typically have one of three shapes: spherical (coccus), oblong (bacillus), or curved (spirillum of vibrio). Depending on the plane of binary fission, cells form chains, clusters with various geometry, or single cells.
Do you need more or less light when viewing a stained preparation?
More light for stained. Less light for unstained. When viewing unstained material, it is necessary to reduce the amount of light to increase the contrast between the cells and the liquid.
Why do scientists stain slides when looking at them?
Bacteria are difficult to see when they are not stained because they are almost colorless. 1. Staining a slide enables a high contrast between the bacteria and the background. 2. It defines the bacterial morphology (size, shape and arrangement). 3. It enables us to observe structures like flagella, capsules and endospores.
Advantages of positive and negative staining for morphological study of bacteria?
Positive staining allows the bacteria to be directly stained and visualized under a microscope, which helps in studying their size, shape, and arrangement. It also provides valuable information about the cell wall structure and composition. Negative staining, on the other hand, allows the visualization of bacteria that are otherwise difficult to stain due to their thin or delicate cell walls. It provides better contrast and allows for the observation of fine morphological details of the bacteria.
What would you expect to see inside the stained cells nucleus?
It would be the color you stained.

What info can you observe on a wet mount that cannot be seen on a stained preparation?
The movement of a bacteria can be seen on a wet mount. This movement can not be seen in a stained preparation.
What is the medical term meaning stained blood smear is examined to determine the shape of individual red blood cells?
The medical term meaning stained blood smear is examined to determine the shape of individual red blood cells is called a peripheral blood smear. This test is commonly used to assess the morphology and appearance of red blood cells, which can provide valuable information about various blood disorders.
What is counterstaining?
Counterstaining means to apply a second stain to a preparation for microscopy. Counterstaining is used to stain in a contrasting way those parts of the preparation that have not been stained by the first stain.
Can cells be stained with dye?
Live staining is possible as is the preparation of fixed tissue.
Do you need more or less light when viewing a stained preparation?
More light for stained. Less light for unstained. When viewing unstained material, it is necessary to reduce the amount of light to increase the contrast between the cells and the liquid.
Why is half the body blue and half the body red?
That is not the case; you are looking at how some dissection specimens have had their veins and arteries stained. It is the dyes used in the preparation of the specimens.
Why are living unstained bacterial preparation more difficult to observe microscopically than stained preparations?
Staining adds contrast making the bacteria easier to see.
What phrase does not describe a Gothic cathedral?
pointed arches and stained-glass windows" does not describe a Gothic cathedral, which in general have more "studded" tops that allow for great room inside.
Can you ditniguish the nucleolus organiser site during interphase in your root tip preparation?
You can distinguish the nucleolus organiser site during interphase in your root tip preparation by taking a dye like iodine and staining the slide so the nucleolus organizer appears stained.
Describe the characteristic of Gothic stained-glass windows?
To illiterate people could understand their illustrated biblical scenes and figures.
