The kingdom that contains prokaryotic organisms is:
A. Fungi
B. Monera
C. Plantae
D. Protista
Answer: Option B
Solution (By JKSSB Mock Tests)
Whittaker's five-kingdom system places all prokaryotes (bacteria, cyanobacteria, archaea) in Monera. They lack a true nucleus and membrane-bound organelles. Protista has unicellular eukaryotes, Fungi and Plantae are multicellular eukaryotes (except yeast). Monera reproduces asexually mainly by binary fission.
Explanation:
The term 'biology' was independently coined by Jean-Baptiste Lamarck (France) and Gottfried Reinhold Treviranus (Germany) around 1802. Aristotle is father of biology, Linnaeus taxonomy, Darwin evolution.
Explanation:
Viruses do not reproduce by binary fission; they replicate by hijacking host cell machinery. Binary fission is a method of asexual reproduction in bacteria. All other statements are correct.
Explanation:
The heart is myogenic because the heartbeat originates in the SA node within the heart itself, not from brain signals. The brain can modulate the rate but not initiate. Thus, A is true, but R is false.
