6 Kingdoms of Life
As living things are constantly being investigated, new attributes are revealed that affect how organisms are placed in a standard classification system.
Carl Linnaeus was a scientist who developed a classification system for living things.
Wrote book Systema
Naturae in 1735 to
reveal his classification
1. Comparing morphology (physical traits)
2. Looking at genetic similarities & differences
3. Biochemical make-ups
4. Behavioral similarities
Origin of Life Video
Cladogram- a branching diagram that shows evolutionary relationships.
We use taxonomy – the science of classifying living things, to help us determine the cladogram.
Genus is always capitalized
Species is always lower case
The whole name is underlined if written or italicized if typed.
Example: Homo sapiens
1stCriteria for Kingdom Divisions:
Prokaryotes or Eukaryotes
2nd criteria for Kingdom Divisions:
3rd Criteria for Kingdom Divisions
Feeding Type - How the organisms get their food
The common bacteria that most people talk about when they say “bacteria”, because they live in more neutral conditions.
a cell wall
Protists include many widely ranging microbes, including slime molds, protozoa and primitive algae.
The “Junk Drawer” Kingdom
Amebic dysentery - is an infection of the intestines caused by the parasite Entamoebahistolytica.
Amebiasis is contracted by consuming contaminated food or water containing the cyst stage of the parasite. It can also be spread by person-to-person contact.
African Sleeping Sickness They are transmitted to humans by tsetse fly (Glossina genus) bites.
Malaria-Malaria is caused by a parasite that is transmitted from one human to another by the bite of infected Anopheles mosquitoes.
Protists can be autotrophs or heterotrophs
The Kingdom Fungi includes some of the most important organisms.
Heterotrophic- break down dead organic material and continue the cycle of nutrients through ecosystems.
Fungi can be very helpful and delicious
Many antibacterial drugs are derived from fungi - penicillin
Fungi accounts for the blue vein in blue cheese!
Fungi live off, or consume dead or decaying plant or animal material which is an important role they play in all ecosystems.
All fungi absorb their food.
Fungi also causes a number of plant and animal diseases:
Fungi are stationary
They have root-like structures that they use for attachment
Mushroom are fungal fruiting bodies.
All plants are multicellular, their cells having a cell wall
Autotrophs-make own carbs for energy through photosynthesis
4 important plant groups are the:
Flowering Plants (Angiosperms)
Nonvascular Plants - Mosses
Vascular Plants-Angiosperms and Gymnosperms
- flowering plants
Criteria for Animal Classification
have a hard external skeleton made of chitin known as an exoskeleton
have a hard internal skeleton made of bone or cartilage
Major phylums of animals are…
Cnidarians: Jellyfish, corals, and other stingers. . . Their stinger is called a nematocyst
Human liver fluke
