grouping together of organisms based on their similarities
-
2 types of classification
taxonomy and systematics
-
(classification) Taxonomy
-study of classification
-naming and identification
-
(classification) Systematics
-study of evolutionary relationships
-
Carl Linnaeus (4)
- father of taxonomy
-devised first useful system of classification
-based ons exual parts and appearance
-used binomial
-
Binomial (3)
-2 parts to a name for each species

Five kingdom system
method to organize living things
-begins at the largest level, Kingdom
-
3 categories that make up the Kingdom system
-Internal organization of cells
-Size of organism
-types of nutrition
-
(kingdom system) Internal organization of cells
Prokaryotic and Eukaryotic
-
Prokaryotic (5)
-before nucleus
-lacks organelles
-most primitive life
-first to evolve here on Earth
ex) Kindom monera: bacteria
-
Eukaryotic (4)
-true nucleus
-has organelles
-evolved from prokaryotic cells
-most living organisms
-
(kingdom system) Size of organism (2)
- -unicellular or single celled
- *ex) kingdom protista: Protozoans, some algae, slime molds
-multicellular
-
(kingdom system) Types of nutrition (3)
-photosynthesis
-Ingestive
-absorbative
-
(types of nutrition) Photosynthesis (2)
-make food from the sunlight
-Kingdom plantae: Plants
-
(types of nutrition) Ingestive (2)
takes food and digest it
-kingdom animalia, Animals
-
(types of nutrition) Absorbative (2)
secrete enzymes to digest food externally and then digest it
kingdom fungi
-
five kingdom names
-monera
-protista
-animalia
-fungi
-plantae
-
(kingdom) Monera
-prokaryotic
-unicellular
ex) archea and bacteria
-
(kingdom) Protista
-eukaryotic
-unicellular
ex) large group can overlap into other kingdoms
-
(kingdom) Animalia
-eukaryotic
-multicellular
-nutrition: ingestion of food
-
(kingdom) fungi
-eukaryotic
-mostly multicellular
nutrition: absortion of food
ex) slime molds and true fungi
-
(kingdom) Plantae
-eukaryotic
-multicellular
nutrition: most are phtosynthetic
- ex) green, red, brown algae
- bryophytes and tracheophytes
