The Five Kingdom Classification Quiz

Kingdom Classification

• Chlamydomonas is originally placed in the kingdom Protista.
• The kingdom Protista lacks cell walls.
• The kingdom Monera groups together prokaryotic organisms.
• The kingdom classification based on evolutionary relationships is the Five Kingdom Classification.
• The kingdom Protista has unicellular eukaryotic organisms.
• The kingdom Fungi and the kingdom Plantae have organisms with cell walls.
• The kingdom Fungi groups together fungi.
• The kingdom Monera is dealt with separately in chapter 3.
• The kingdom Protista is dealt with separately in chapter 4.
• The kingdom classification based on morphological, physiological, and reproductive similarities is the traditional classification.
• The scientist who proposed the Five Kingdom Classification is R.H. Whittaker.
• The five kingdoms defined by R.H. Whittaker are Monera, Protista, Fungi, Plantae, and Animalia.
• The main criteria for classification used by R.H. Whittaker are cell structure, body organization, and nutrition.

Characteristics of Kingdoms

• The cell wall composition of fungi and green plants differs: fungi have chitin, while green plants have cellulose.
• The kingdom Monera groups together prokaryotic bacteria and the blue-green algae (cyanobacteria).
• The kingdom Protista groups together unicellular organisms like Chlamydomonas and Spirogyra.

Evolution of Classification Systems

• The earlier classification systems were based on morphological and physiological characteristics.
• The characteristic that unified the organisms included under 'Plants' in earlier classification systems is the ability to photosynthesize.
• The earlier classification systems included algae and green plants under 'Plants'.
• The two groups placed together under algae in the earlier classification systems are Chlamydomonas and Spirogyra.
• The proposed system that divides the Kingdom Monera into two domains is the three-domain system.

Miscellaneous

• The main difference in the cell wall composition between fungi and green plants is the presence of chitin and cellulose, respectively.
• A characteristic NOT used by R.H. Whittaker for classification is evolutionary relationships.
• The kingdom dealt with separately in higher classes is Monera.
