1 Day 11 Is this what E. coli would look like under a microscope? This is a better idea of what it would look like.

2 Compare Domains Contrasting Case Activity 2.5a Investigation 2.5 – Kingdoms of Life

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

6 Domain and Kingdom Chart Living Things Domains Kingdoms ArchaeaEukarya ProtistsFungiPlantsAnimals 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) Found on land, in rainforests in Africa Moves by walking upright and on all fours Eats fruits, leaves, and small animals found in its environment Reproduces sexually Bonobo Kingdom Animalia

Made up of many different kinds of cells; each cell has a nucleus (Eukaryote) Found in marine environments; attached to hard substances Moves by swimming when young; adults are immobile Feeds on plankton found in its environment Reproduces sexually Barnacle Kingdom Animalia

L. acidophilus Made up of one cell that has a cell wall but not a nucleus (Prokaryote) Found in warm, acidic environments, common in human and animal intestines Moves by using a flagellum Metabolizes sugars found in its environment Reproduces asexually Domain Bacteria

Made up of one cell that has a cell wall but not a nucleus (Prokaryote) Found in many different environments; common in human and animal intestines Moves by using a flagellum Metabolizes sugars found in its environment Reproduces asexually E. coli Domain Bacteria

Halobacteria Domain Archaea Made up of one cell without a nucleus (Prokaryote) Found in salt water environments Moves by using a flagellum Uses sunlight for energy Reproduces asexually

Ferroplasma Domain Archaea Made up of one cell, without a nucleus (Prokaryote) Found in acidic mine environments Propelled by flagella Obtains energy from oxidation of iron in pyrite Reproduces asexually
