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

6
Domain and Kingdom Chart
7
Kingdom Protista
Algae

• 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

8
Kingdom Protista
Paramecium

• 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

9
Destroying angel
Kingdom Fungi

• Made up of many cells each cell has at least one
  nucleus (Eukaryote)
