StandardsS7L1bAt the end of this lesson, you will be able to classify organisms into one of the six kingdoms based on physical characteristics.

OverviewLesson Title: 6 Kingdoms

Lesson Description: This lesson will introduce the six kingdoms and will provide descriptions and examples of each.

RationalIt is important for you to know this information because as we move through our study of ecology, you will begin to see how organisms, no matter their kingdom, depend on one another for basic needs in order to survive.

Essential QuestionHow can learning about the six kingdoms help us better understand our world?

Prior LearningYou recently learned what an organism is and the characteristics of all living things. You will now apply what you have already learned to gain a better understanding of the physical characteristics of each of the six kingdoms.

ArchaebacteriaStructural organization: Unicellular, prokaryoticHow energy is obtained: Producers, consumers, or decomposersExamples: thermophiles, halophiles, methanogensOther info: 1. Live in hostile places where other organisms cannot survive – hot springs, salty, acidic environments2.3 Categories – salt-, heat-, and acid-lovers3.Some are methane producers – are anaerobic4.Archae means “old” – oldest known organisms on Earth

Archaebacteria

Hot Springs of Yellowstone National Park

Halobacteria

EubacteriaStructural organization: Unicellular, prokaryoticHow energy is obtained: Producers, consumers, or decomposersExamples: cynobacteria, gram positiveOther info: 1. Most common – live in water, soil, inside and on human body; can be harmful or helpful2.Larger of 2 bacteria kingdoms3.Grouped according the cell shape and structure

Eubacteria

E. coli

ProtistaStructural organization: Most unicellular, some multicellular, eukaryoticHow energy is obtained: Producers, consumers, or decomposersExamples: 3 categories: 1.plant-like (algae – producers)2. animal-like, (protozoans – consumers)3. fungus-like (slime molds – decomposers)

Other info: 1. Evolved from bacteria about 2 billion years agoClick here for more info:http://glencoe.mheducation.com/sites/dl/free/0078617022/164155/00044685.html

Protista

Fungus-like - Slime MoldAnimal-like - Protoza

Plant-like – Algae

FungiStructural organization: Multicellular or unicellular, eukaryoticHow energy is obtained: Heterotrophs (decomposers) – get food from outside sourceExamples: molds, mushrooms, yeastOther info: 1. Cell wall of chitin2.Absorb nutrients by breaking down organic material

Fungi

Yeast

Mushrooms

Mold

PlantaeStructural organization: Multicellular, eukaryoticHow energy is obtained: Autotrophs (producers) – make their own food using photosynthesisExamples: trees, ferns, flowers, mosses Other info: 1. Cell wall of cellulose2.Usually green – contain chlorophyll3.2 categories: vascular, non-vascular

Plantae

Ferns

Trees

AnimaliaStructural organization: Multicellular, eukaryoticHow energy is obtained: Heterotrophs (consumers)Examples: Humans, insects, reptiles, amphibians, worms, spongesOther info: 1. Most can move from place to place2.Usually green – contain chlorophyll3.2 categories: vertebrates, invertebrates

Animalia• Most complex multicellular organisms• Eukaryote• Most can move from place to place• 2 categories:

1. Vertebrates – nervous columnEx: reptiles, amphibians, people

2.Invertebrates – no nerve columnEx: sponge, worms, bugs

• Consumers/Heterotrophs – herbivores, carnivores, or omnivores

Student Practice• You will use your notes to complete the

corresponding boxes for all six kingdoms on the Keys to the Kingdom Activity.
