3
Introduction• Which of these organisms do you have the most in common with?
4
Classification
Organisms are divided into groups known as Domains and Kingdoms.
What do you think would be the best way to classify organisms into groups?(answers will vary)
5
More about Classification
The classification into Domains and Kingdoms is mainly based on:
•Cell structure•How they obtain energy•How they reproduce

Domains
Kingdoms
Archaea Eukarya
Protists Fungi Plants Animals
Bacteria
Kingdom Protista
• Made up of one or more cells; each cell has a nucleus (Eukaryote)
• Found in freshwater and marine environments
• Some are mobile and have flagella• Makes its own food by photosynthesis and absorbs nutrients from its environment
• Reproduces asexually and sexually
Algae
Kingdom Protista
• Made up of one cell; has a nucleus (Eukaryote)
• Found in freshwater environments, commonly in scums
• Mobile: uses cilia for locomotion• Uses cilia to sweep up food found in its environment
• Reproduces asexually and sexually
Paramecium
Destroying angel
• Made up of many cells; each cell has at least one nucleus (Eukaryote)
• Found on land, usually near trees or shrubs
• Immobile• Absorbs nutrients from its environment
• Reproduces asexually and sexually• Extremely poisonous
Kingdom Fungi
Yeast
• Made up of one cell that has a nucleus (Eukaryote)
• Found on land and in freshwater and marine environments
• Immobile• Absorbs nutrients from its environment
• Reproduces asexually or sexually• Used in baking bread and brewing beer
Kingdom Fungi
Cactus
• Made up of many different kinds of cells; each cell has a nucleus and a cell wall (Eukaryote)
• Found on land, in desert environments
• Immobile• Makes its own food by photosynthesis• Reproduces sexually
Kingdom Plantae
Elodea
• Made up of many different kinds of cells; each cell has a nucleus and a cell wall (Eukaryote)
• Found underwater, throughout North America
• Immobile• Makes its own food by photosynthesis
• Reproduces sexually
Kingdom Plantae
• Made up of many different kinds of cells; each cell has a nucleus (Eukaryote)
