OCE Chap 12 Questions with Correct Answers (Grade A+)
Question 1: A plankton biologist has discovered a new species and he needs your help classifying it into
a proper kingdom. All you can observe is that this microscopic organism has just one nucleus in its cell
and it has chlorophyll so it must be photsynthetic. What kingdom does it belong to? Plantae Animalia
Monera Protoctista Fungi
Answer: Protoctista
Question 2: Which of the following statements concerning bacteria is FALSE? Bacteria were the first
type of cells to evolve on earth. Bacteria lack membrane-bound organelles and a distinct nucleus
surrounded by a nuclear membrane. Bacteria have a cell membrane and a cell wall. Bacteria are found
in both Kingdom Monera and Kingdom Protoctista. Bacteria can be found living in extreme
environments (heat, salinity, cold, etc.).
Answer: bacteria are found in both Kingdom Monera and Kingdom Protoctista
Question 3: Which of the following associations is INCORRECT? Kingdom Plantae—algae Kingdom
Protoctista—phytoplankton Kingdom Fungi—mushrooms Kingdom Animalia—dolphins Kingdom
Monera—bacteria in hydrothermal vents
