FIVE KINGDOM CLASSIFICATION

R.H. Whittaker: The scientist who proposed the five-kingdom classification system.

Five Kingdoms:

Monera: Organisms with no true nucleus (prokaryotic).

Protista: Single-celled eukaryotic organisms.

Fungi: Heterotrophic, eukaryotic organisms with cell walls.

Plantae: Multicellular, eukaryotic, autotrophic (food-producing) organisms with cellulose cell walls.

Animalia: Multicellular, eukaryotic, heterotrophic organisms without cell walls.

Cellular Structure: Distinguishes between prokaryotic (Monera) and eukaryotic (Protista, Fungi, Plantae, Animalia) cells.

Nutrition: Describes how organisms obtain food; autotrophic (plants) and heterotrophic (fungi, animals).

Cell Wall: Key features include the presence and composition of a cell wall, such as cellulose in plants and chitin in fungi.

Examples: Specific examples for each kingdom to illustrate the concept, such as :
Bacteria (Monera),
Amoeba (Protista),
Mushroom (Fungi),
Mango tree (Plantae), and
Lion (Animalia).

Classification: The process of grouping organisms based on similarities and differences.
