Biology Kingdoms Overview Quiz

Kingdoms Overview

• Archaebacteria and Eubacteria are both classified as prokaryotes, meaning they lack a nucleus.
• Eubacteria includes common microorganisms such as E. coli and Streptococcus, while Archaebacteria can thrive in extreme environments like hot springs.
• The three remaining kingdoms (Protists, Fungi, Plants, Animals) are eukaryotic, possessing a nucleus.

Prokaryotes vs Eukaryotes

• Prokaryotes are defined as organisms without a nucleus.
• Eukaryotes have a distinct nucleus and organize their genetic material within it.

Nutritional Modes

• Autotrophs are organisms that produce their own food through processes like photosynthesis or chemosynthesis.
• Heterotrophs depend on consuming other organisms for nutrition.

Unicellular vs Multicellular

• Unicellular organisms consist of a single cell, while multicellular organisms are composed of multiple cells.
• Archaebacteria and Eubacteria are unicellular, while Protists can be both unicellular and multicellular.

Kingdom Characteristics

• Archaebacteria: Prokaryotic, both autotroph and heterotroph, unicellular, and known for living in extreme conditions.
• Eubacteria: Prokaryotic, both autotroph and heterotroph, unicellular, and includes well-known species like E. coli.
• Protists: Eukaryotic, both autotroph and heterotroph, can be unicellular (e.g., amoeba) or multicellular (e.g., seaweed).
• Fungi: Eukaryotic, heterotrophic, can be unicellular (e.g., yeast) or multicellular (e.g., mushrooms).
• Plants: Eukaryotic, autotrophic, and exclusively multicellular; examples include roses and ferns.
• Animals: Eukaryotic, heterotrophic, and multicellular; includes a wide variety of organisms such as lions and bears.

Examples of Organisms by Kingdom

• Archaebacteria: Thrive in extreme environments like hot springs.
• Eubacteria: Includes organisms such as E. coli and Streptococcus.
• Protists: Comprises algae, amoeba, and seaweed.
• Fungi: Represents yeast, mold, and mushrooms.
• Plants: Features plants like rose bushes, redwoods, and ferns.
• Animals: Encompasses diverse species, such as lions, tigers, and bears.
