Microscopic examination
The analysis of minute organisms, cellular organization of any biological structure, and composition of body fluids with the help of a microscope is known as microscopic examination. The magnification of specimens or samples under study helps in attaining a clearer picture of it.
Gram Staining
Named after Hans Christian Gram, a Danish bacteriologist, Gram stain is one of the most powerful staining techniques within microbiology. This technique was introduced in 1882 to identify pneumonia-causing organisms. The Gram staining technique uses crystal violet or methylene blue as primary staining colors to distinguish gram-positive from gram-negative organisms. Under a microscope, the gram-positive organisms appear purple-brown, retaining the primary color. Gram-negative organisms appear pink or red as they do not acquire the color of the primary stain.

- Part B. Please turn in typewritten answers to the following questions 1. Asexual reproduction in diatoms occurs when the two valves move slightly apart and the cell divides in a plane parallel to the valves. A new valve is formed which nests within the parent valve. What happens to the average cell size in a population of diatoms reproducing in this manner? How has diatom life history evolved to resolve this issue of changing cell size? Explain. 2. Many benthic invertebrates produce planktonic larvae. Please provide a rationale for a meroplanktonic lifestyle. That is, what are the putative advantages of spending only part of the life cycle in the plankton? 3. Many species of zooplankton will undergo daily vertical migrations, spending the daylight hours lower in the water column and the evening hours closer to the surface. Please speculate as to why so many species display this common behavior.Instruction: For the first 2 columns, fill in the missing data to complete the table.
