Concept explainers
To explain: How microscopy and biochemistry complement each other to reveal cell structure and function.
Introduction: Microscopy is the use of microscope to see an object that is not visible to the naked eye. Light microscopy uses the light to view the specimen and in electron microscopy, a beam of electron is used to view the specimen. With the help of a light microscope, it is possible to view different cell types, bacteria, algae, and
Explanation of Solution
Microscope is an instrument used to observe minute organisms that are invisible to the naked eyes. The first microscope was devised by Anton von Leeuwenhoek and later several modifications were made. The most commonly used microscopes are light microscope and electron microscope. The electron microscopy and light electron microscopy permit the cells to be studied visually, and they help in understanding the internal structure of the cell and arrangement of the cell components. The different groups of cellular components that are separated by cell fractionation techniques are able to analyze biochemically to determine their function. The correlation between the biochemical function of the cell and the cell component can be found by performing microscopy on the same cell fraction. Microscopy is used to view the tissue, plant, or animal cell or any other organism. Both the plant and animal cell have various organelles that can be separated by cell fractionation. The staining method can be used to analyze different structural and functional properties of the cell or isolated organelles.

- discuss the way that developments in microscopy havechanged our view of cell structure; andarrow_forwardDuring a microscopy exercise in the anatomy laboratory,a student makes the following observations about a tissuesection: (1) The section contains some different types ofscattered protein fibers—that is, they exhibit differentwidths, some are branched, some are long and unbranched,and their staining characteristics differ (some are seenonly with specific stains). (2) Several cell types withdifferent morphologies are scattered throughout the section,but these cells are not grouped tightly together. (3) Theexamined section has some “open spaces”—that is, placesbetween cells and the observed fibers in the section thatappear clear with no recognizable features. What type oftissue is the student observing? Where might this tissue befound in the body?arrow_forwardHow have microscopes advanced the study of cells?arrow_forward

(also explain) For visualizing the fine structure of cellular organelles and cell architecture in the cell interior using very thin cross-sections made in Epon. To obtain sequential images of a macromolecule in order to study its activity in real-time. To obtain an extremely clear three-dimensional image of the nucleus of a single cell.

Note that more than one letter may apply for a particular function and that each letter may be used more than once or not at all. A) Gap junctions provides a very strong attachment point between cells B) Desmosomes allow easy movement of large amounts of substances between adjacent cells C) Plasmodesmata seals the plasma membranes of adjacent cells together, preventing the movement of molecules between them D) Tight junctionsarrow_forwardWhat are the advantages of using many varied methods to connect structure and function in cells?
