Study Notes
Five Kingdom Classification
- Proposed by R.H. Whittaker in 1969, encompassing Monera, Protista, Fungi, Plantae, and Animalia.
- Classification criteria include cell structure, body organization, mode of nutrition, reproduction, and phylogenetic relationships.
Characteristics Overview
-
Monera
- Cell Type: Prokaryotic.
- Cell Wall: Noncellulosic composed of polysaccharides and amino acids.
- Nuclear Membrane: Absent.
- Body Organization: Cellular.
- Mode of Nutrition: Autotrophic, including both chemosynthetic and photosynthetic methods.
-
Protista
- Cell Type: Eukaryotic.
- Cell Wall: Present in some organisms.
- Nuclear Membrane: Present.
- Body Organization: Cellular.
- Mode of Nutrition: Primarily heterotrophic.
-
Fungi
- Cell Type: Eukaryotic.
- Cell Wall: Composed of chitin.
- Nuclear Membrane: Present.
- Body Organization: Multicellular or loose tissue.
- Mode of Nutrition: Heterotrophic, mainly saprophytic.
-
Plantae
- Cell Type: Eukaryotic.
- Cell Wall: Composed of cellulose.
- Nuclear Membrane: Present.
- Body Organization: Organized into tissues, organs, and organ systems.
- Mode of Nutrition: Autotrophic, primarily photosynthetic.
-
Animalia
- Cell Type: Eukaryotic.
- Cell Wall: Absent.
- Nuclear Membrane: Present.
- Body Organization: Organized into tissues, organs, and organ systems.
- Mode of Nutrition: Heterotrophic, encompassing holozoic and saprophytic methods.
Six Kingdom Classification
- An alternative classification is the three-domain system.
- This system divides Monera into two distinct domains.
- Remaining eukaryotic kingdoms are classified within a third domain, effectively creating a six kingdom classification.
