What microscope must you slice specimens very small?
A transmission electron microscope (TEM) is used to examine thin slices of specimens that are typically less than 100 nanometers thick. This type of microscope can provide ultra-high resolution images by passing electrons through the specimen to create detailed images of the internal structures.
Why must a specimen be thin in order to be viewed under the microscope?
Specimens must be thin in order to be viewed under the microscope because light can only pass through a certain thickness of material. A thin specimen allows light to pass through and interact with the cells, allowing the microscope to produce a magnified image. Thicker specimens would prevent light from passing through and produce a blurry or unreadable image.
Why robert hooke had to take thin slices of cork?
Robert Hooke took thin slices of cork to observe its structure under a microscope. By examining the tiny cells and compartments in the cork, he was able to make detailed observations about its composition and structure, leading to his discovery of cells.
What term refers to images of very thin slices of the brain?
The term is "brain sectioning." This technique involves cutting brain tissue into thin slices, typically using a microtome, to allow for detailed examination under a microscope.
Which microscope is used to see the cross section of a stem?
A compound light microscope is commonly used to see the cross section of a stem. This microscope uses multiple lenses to view thin slices of specimens that have been mounted on slides. It is particularly useful for observing the internal structures of biological samples.
What do crisps have in them?
Crisps, (or 'chips' in north America) have the base material, usually thin potato slices and fat that it's cooked in.
How are biopsy specimens handled?
Biopsy specimens are often sliced into thin slices, stained, mounted on a glass slide, and examined using a light microscope. Newer sample preparation techniques involve the rapid freezing of the sample and slicing of the still-frozen material.
Thin flattened slices of veal leg usually cooked by sauteeing?
Thin slices of veal cut from the leg are called cutlets, scallops, or scaloppini.
What is the homophone for to cut thin slices and a fruit?
The homophone for "to cut thin slices" is "pear" as in the fruit "pear."
What are the homophones for to cut thin slices and a common fruit?
The homophones for "to cut thin slices" are "pare" and "pear" (fruit).
What is a homophone for to cut thin slices?
A homophone for "to cut thin slices" is "to cut thinly" or "to slice thin." These terms have different spellings and meanings but sound the same when spoken aloud.
What is the homophone for to cut thin slices or a common fruit?
The homophone for "to cut thin slices" is "pear" which sounds like "pare."
What are sections thin slices of specimens used for in science laboratories?
Biological thin specimens may be flash frozen using dry ice or liquid nitrogen and the sample is then embedded in paraffin wax or some similar material. From this block, thin sections are shaved off; often tens of samples; and these then may be transferred to a suitable mount for microscopic inspection.The shaving is usually done with the sharp edge of a specially prepared glass blade, and the the whole assembly is known as a microtome.This technique is used for plant or other bio tissue samples. For example, one could thus make a serial sections of a worm, allowing one to follow the location and shape of various organs in the body. Such as hearts or nephridia.Geological thin specimens are also prepared for microscope inspection. The rock sample is mounted on a suitable carrier, and a smooth face is prepared using fine grinding techniques. The smooth face is then adhered to the smooth face of a carrier, and the remainder of the rock is then ground away until only a thin section remains. Using a transparent carrier allows the progress of the grinding to be monitored.This is inspected under polarized light, and is an informative way of determining the minerals present.

Compare the process used to produce a TEM and an SEM?
The process used to produce TEM will cut cells and tissues in to ultra-thin slices so that they can be viewed under the microscope. However, the ones on SEM do not need to be cut as they can easily be visualized.
What was Hooke observing when he discovered cells?
Thin slices of cork
