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

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)
