What research microscope is used to see unstained living microbes and intracellular structures?
The microscope that is used to see internal structures of cells in a natural state is the compound light microscope. The microscope has a lens and light that allows it to see the internal structures of a cell clearly.
What is a phase microscope?
A phase-contrast microscope (or phase-difference microscope or phase microscope) allows better viewing of clear specimens that usually need to be stained before you can make out the various parts. Staining is a time consuming process and kills the cells being viewed. With a phase-contrast microscope, living cells can be studied as they go through the cell division cycle.HOW IT WORKSAs light goes through a transparent specimen, there may not be anything interesting to see. However, the light undergoes phase changes as it passes through the different parts of the specimen. Unfortunately, the human eye does not notice phase changes. A phase-contrast microscope converts these unnoticed phase changes into differences in brightness, which the human eye sees very well. The darker and lighter parts of the specimen make it very visible.This also works on reflected light microscopes.
In what part of the cell cycle will you see chromatin and not chromosomes?
telophase. in this phase the chromosome disperse and you can't see the chromosome anymore throught the light microscope.
What structure of the mammalian cell are proteins synthesized?
Ribosomes
What stage of mitosis does a cell spend most of it's life?
When we look at the cell cycle, we see that the genome doubles (replicates itself) during the S phase. Since the M (mitosis) phase comes after the S and G2 phases, prophase of mitosis has the maximum number of chromosomes. Here, there are two copies of the genome.
What is the restriction point in mammalian cells?
In the mammalian cell cycle, a time late in the G1 phase at which the cell commits to the replication of its deoxyribonucleic acid (DNA).
What microscope takes advantage of of refractive indexes of cell structure?
The microscope that takes advantage of differences in the refractive indexes of cell structure is the phase contrast microscope. The microscope that is used to see internal structure of cells in a natural state is also a phase contrast microscope.
Ron is observing an onion cell on a slide under a microscope He sees chromatids being pulled to opposite ends of the cell Which phase is he seeing?

Which phase of the cell cycle could you identify most readily with a light microscope Explain your answer?
prophase and metaphase

If you examine a population of intestinal epithelial cells under a microscope most of the cells would appear in what phase of the cell cycle?
. be in mitosis.
The relationship of the cell and the microscope?
A cell is a structure which is present inside everything in this world and a microscope is an electronic machine which enables people to see these cells. A cell is classified into plant cell and animal cell and a microscope is classified into electronic microscope and ordinary microscope. Plant cell has cell wall and cell membrane and animal cell has vacuole and nucleus. Electron microscope uses electrons and an ordinary microscope uses simple glass plate. There is also another type of microscope called light microscope which uses light.

Unfortunately, the human eye does not notice phase changes.A phase-difference microscope converts these unnoticed phase changes into differences in brightness, which the human eye sees very well. The darker and lighter parts of the specimen make it very visible - and it is still alive!This also works on reflected light microscopes.

How would you make a cell phone microscope?
You cannot make a cell phone microscope. A cell phone is for talking and to text.
