The name given to a liquid used to make cells structures easier to see?
A stain is a liquid used to make cell structures easier to see by adding color contrast. Stains can highlight specific parts of cells, making them more visible under a microscope. Different stains target different cell components or characteristics.
Are cell membranes visible under a microscope?
Cell membranes are not typically visible under a light microscope because they are thin and transparent. However, special staining techniques or electron microscopy can be used to make cell membranes visible.
How to count algae cells in a microscope?
To count algae cells in a microscope, prepare a sample of the algae suspension, pipette a known volume onto a counting chamber slide, place it under the microscope, and count the cells within a representative grid area. Calculate the concentration of algae cells per unit volume based on the average cell count in the grid. Remember to consider the dilution factor if you diluted the sample before counting.
Why did it take so long after to discover that all living things are made of cells?
Probably the single biggest reason is that cells are of a size too small to be seen by the naked eye - or even with a magnifying glass. They could not be observed and studied until the invention of the microscope. According to Wikipedia:The first microscope to be developed was the optical microscope, although the original inventor is not easy to identify. An early microscope was made in 1590 in Middelburg, Netherlands. Two eyeglass makers are variously given credit: Hans Lippershey (who developed an early telescope) and Zacharias Janssen. Giovanni Faber coined the name microscope for Galileo Galilei's compound microscope in 1625so it would seem that there were no microscopes until around the 16th century.The first detailed account of the interior construction of living tissue based on the use of a microscope was not published until 1644, in Giambattista Odierna's L'occhio della mosca, or The Fly's Eye.
If you were given a slide containing living cells how would you identify the cells as either plant ior animal?
To identify cells as either plant or animal, I would look for key distinguishing features. Plant cells typically have a rigid cell wall, chloroplasts for photosynthesis, and large central vacuoles, while animal cells lack these structures. Additionally, I would check for the presence of specific organelles: animal cells have lysosomes, which are rare in plant cells. Observing these characteristics under a microscope would help in determining the type of cells present.
Which scientist is given credit for viewing cells under the microscope but not naming them cells?
Leeuvenhoek

Who was the Dutch scientist who improved the microscope?
The first microscope to be developed was the optical microscope. An early microscope was made in 1590 in Middelburg, Netherlands. Two eyeglass makers are variously given credit: Hans Lippershey (who developed an early telescope) and Zacharias Janssen. Van Leeuwenhoek improved a microscope and first described cells seen in cork tissue. He called them cells as they looked like little rooms, similar to ones that monks lived in.
Why are white blood cells in a stained blood smear usually counted at low power under a microscope?
Due to the limited field of vision of microscopes, it is comparatively easier to count the number of white blood cells in a stained blood smear under low power than under high magnification. Although the individual cells would be smaller and thus more difficult to count, there would be more in view at any given time.
Is van leeuwenhoek given credit for developing the first microscope?
Yes, Antonie van Leeuwenhoek is often credited with developing the first practical microscope in the 17th century. He was a Dutch scientist who made significant advancements in microscopy and was the first to observe and document bacteria, red blood cells, and sperm cells using his microscopes.
What is range names?
In a spreadsheet, a cell or a group of cells can be given a name to make them easier to reference. So a list of sales in cells for B2 to B25, could be give the range name "Sales" which could then be used in formulas instead of the cell range reference. This makes it easier for users instead of having to remember what cells a range is made up of. The first of these two would be easier to remember and makes the formula a lot clearer:=SUM(Sales)=SUM(B2:B25)In a spreadsheet, a cell or a group of cells can be given a name to make them easier to reference.

What happens when cells are given nutrients?
When cells are given nutrients, they metabolize them, and grow and divide to create more cells. If they are not given nutrients, they die.
What is the name given to two chemicals?
compound
Does energy get released when chemicals react?
Yes, energy is given off when chemicals react. Since energy can be heat or light it is also given off.
Who is given the credit for the invention of the microscope?
The credit for inventing the microscope is generally given to Dutch spectacle maker Zacharias Janssen and his father Hans in the late 16th century. They are believed to have created the first compound microscope consisting of multiple lenses for magnification.
Is a street a cell?
No. The term (in science) means a small enclosed space. It was given to cells (in plants and animals) seen under a microscope by a scientist who said that they reminded him of the small rooms that monks spent most of their time.
What name is given to chemicals that react in a reaction.?
Reactants.
