Explanation & Answer

Hey there, I noticed an error in the earlier version I sent, please use this one, thanks again!
Please define these words giving some differences or examples if necessary:
Bacteria: Rods and Cocci, Fungus, Virus and Parasite
Bacteria is defined as a member of a large collection of unicellular microorganisms that
have cell walls but lack organelles and an organized nucleus, including some that can cause
disease. A coccobacillus (plural coccobacilli) is a sort of rod-shaped bacteria. The word
coccobacillus describs shape between coccus (spherical) and bacillus (elongated). Coccobacilli
rods are so small and wide that they bear a resemblance to cocci. An example of rods are
azotobacter and rhizobium. Species of Azotobacter and Rhizobium are exceptionally significant
for their capacity to fix nitrogen in the environment. These Gram‐negative rods live free in the
soil (Azotobacter) or on the roots of legume plants (Rhizobium) and use their enzymes to change
atmospheric nitrogen into organic molecules useful to the plant. An example among the gram‐
negative cocci are a set of anaerobic diplococci belonging to the genus Veillonella. Veillonella
species are part of the normal flora of the mouth and gastrointestinal tract, and they are found in
dental plaque. They are anaerobic organisms that may cause infections of the female genital tract
as well.
Fungi are found to be dissimilar to viruses as well bacteria on several counts. They are
bigger, plant-like organisms that do not contain chlorophyll. Because fungi do not have
chlorophyll to create food, they must absorb food from whatever they are growing on.. Types of
fungus include mushrooms and yeast.
A virus is a miniscule particle that has the ability infect the cells of a biological organism.
An example of a virus is one that infects bacteria is known as a bacteriophage, regularly
shortened to phage. Parasites are defined as an organism that lives in or on another organism (its
host) and aids by deriving nutrients at the host's expense. An example of a parasite are
tapeworms that are segmented flatworms that attach themselve...
