Question 1 Report
The diagram shows the organism seen under the microscope.
An organism seen under a microscope is a single cell, has no true nucleus, and its cell wall is not made of cellulose. Which group does it belong to?
Answer Details
The decisive clue is the absence of a true nucleus. Only prokaryotes (bacteria) have their genetic material as a loop of DNA free in the cytoplasm rather than enclosed in a nuclear membrane, and their cell wall is not made of cellulose. Protoctists and fungi are ruled out because, although they can be simple, their cells do contain a true nucleus, and plant cells have both a nucleus and a cellulose wall. Whenever an organism is described as single-celled with no nucleus, classify it as a bacterium.
