You are given a new microbe to analyze in your research lab, You discover that this microorganism is unicellular, contains a cell wall, undergoes chemical metabolism, and lacks a membrane-bound nucleus. Based on your findings, you conclude that this microorganism is most likely a:
To answer this question, it would be appropriate to define each of them based on the criteria that the question has imposed.
a. Bacteria- has cell wall, unicellular, has no membrane bound nucleus and it does chemical metabolism.
b. virus does not contain a cell wall, it does not undergo chemical metabolism unless it is inside a host host cell. They have no nucleus and cannot be classified as a cell.
c. Protozoans have no cell walls instead they have cell membranes. They do undergo chemical metabolism and are unicellular.
d. Algae - not all algae are unicellular. They contain cell wall and perform chemical metabolism. They also have membrane bound nucleus.
e. Fungi- not all fungi are unicellular. They contain cell walls which are composed primarily of chitin and performs chemical metabolism. They have membrane bound nucleus.
Only bacteria (letter a) has all the requirement in the question.
Therefore the answer is letter A. Bacteria
hope this helps :)
