QUESTIONS Completion 1. The main reason that microorganisms are stained with basic dyes is 2. Heat fixation accomplishes two things necessary for staining: and 3. Most bacteria are of two basic cell shapes: cylinders and Cylindrical cells may be straight rods or some variation such as 4. is the length of an average Escherichia coll cell. In contrast, most eucaryotic cells, such as yeast and molds, have a diameter that is about times larger than this. ige called, and filamentous fungi are called In contrast, spherical bacteria are called 5. Spherical fungi 6. Some procaryotic bacteria and eucaryotie fungi grow in the shape of filaments However, using the brightfield microscope, filamentous bacteria can be distinguished from filamentous fungi by - 7. The procedures given in this exercise make it easy to tell which side of the slide contains your smear because 8. A stained smear that is properly made should show aboutcells per oil-immersion field and color when examined with the unaided eye. It should also contain written at the end of the slide on the same side as the stained smear. and has a 9. Staphylococcus epidermidis has the shape of a (procaryotic or eucaryotic) cell type. True-False (correct all false statements) 1. Most bacteria have flexible cell walls 2. Spherical bacteria are called cnccl and are typically five to ten times larger than the typical Escherichia coli cell MacBook Air 44 F7 FSExplanation / Answer
as per chegg guidelines if you post more than one questions i have to answer only one
ques3-
most bacteria are of two basic cell shapes cylindrical and round (cocci) shape. cylinderical cells may be straight rods or some variations such as flagellated rods,chain of bacilli or sprue former.
EXPLANATION --
mostly bacteria are of 3 shapes ie 1) coccal(round) -- eg diplococci, streptococci, staphylococci etc
2) bacilli (cylinderical or rod shaped) --eg salmonella typhi , clostridium botulinum etc
3)spiral shape -- eg vibrio cholera, treponema palladium etc
ques9 -- staphylococcus epidermidis has the shape of cocci (sphere) and is arranged in grape-like clusters. and has a prokaryotic cell type.
