Practice questions testing deep understanding of the Five Kingdom system, Monera, Protista, and Fungi.
Q1. Archaebacteria are capable of surviving in the most extreme, harsh environments on Earth (like boiling hot springs or highly acidic salt pans) where all normal eubacteria would instantly die. Explain the specific structural difference at the cellular level that grants them this extreme survivability.
Q2. A researcher finds a microscopic, single-celled organism in a pond. It has a well-defined nucleus, chloroplasts for photosynthesis in the light, but lacks a cell wall. In the dark, it behaves like a predator and ingests smaller microbes. Based on Whittaker's classification, which specific group does this organism belong to, and why was it problematic in older classification systems?
Q3. Assertion (A): Viruses, Viroids, and Prions are not placed in any of the Five Kingdoms. Reason (R): The Five Kingdom system is based on cellular organization, and viruses/prions are acellular (non-cellular) entities that are not truly living outside a host.
