Q: What is the cellular arrangement of the staphylococcus epidermis?
A variety of different microscopes can be used to visualize the sub-cellular structures in a cell. They can be:a bright field microscope (simple in construction but not very accurate)A phase contrast microscope (gives a better idea of the three dimensional orientation of the sub-cellular structures)A fluorescent microscope (the most specific type of scope. This allows one to see very specific structures like the individual strands of actin that make up the cytoskeleton)
The outermost cellular layer
Light microscopes can observe objects of 100 nm- 1 mm. Electron microscopes can observe objects of 1 nm-100 µm.
multi cellular
deepest cellular layer of the epidermis
the upper epidermis is more cutinized,to prevent excess loss of water from the leaf surface
Can you see a spider without a microscope? Then it must be multi-cellular, yes.
because the invention of the electron microscope helps us in the community by helping us understand the cellular functions.
Actually, it depends on the specimen which you are observing.. Suppose, if you are observing Tissues then you have to switch to 10X objective; but if you are observing mammalian cells or other cellular specimen then you have to switch to 45X objective...But, if you want to observe microbial cells then you have to put a drop a drop of paraffin oil on the smear made on the slide and then observe it into 100X oil immersion objectivelens...

A bioscope scan is a technology used in observing and studying samples at a cellular level. It involves scanning a sample with a beam of electrons to create a magnified image, allowing researchers to analyze the internal structures of cells and tissues in great detail. This method is commonly used in fields such as biology, medicine, and materials science to visualize objects that are too small to be seen with a traditional light microscope.
