contains chemicals of life; use and produce energy; respond; reproduce; are all made of cells; grow and develop
|
|
|
4 Basic needs of living things
|
food; water; living space; stable internal conditions
|
|
|
Spontaneous Generation
|
Theory that living thing could come from nonliving things
|
|
|
Francesco Redi
|
First to try and disprove spontaneous generation: had a controlled experiment with meat in two container with one lid on and the other lid was on.
|
|
|
Aristotle
|
Greek scholar who prodcued the first classification system for animals over 2000 years ago. Organized them into 3 groups based on where they were found : in water; could fly; could run walk or crawl
|
|
|
Carolus Linnaeus
|
created the system of classification naming organisms as they still are today. Organized on similar features. Also gave each organism a unique two name name called Binomial Nomendature
|
|
|
Louis Pasture
|
Second to try to disprove spontaneous generation;two pots of broth, one boiled the other not.; built on top of Francesco Redi’s concept
|
|
|
Taxonomy
|
the scientific study of how living things are classified
|
|
|
Field Guide
|
books with illustrations that could highlight differences between similar looking organism
|
|
|
Taxonomic Key
|
consists of a series of paired statements that describe the physical characteristics of different organisms
|
|
|
Dichotomous Keys
|
are a list of traits used to identify a specific organism
|
|
|
Classification (Definition; Why Classify)
|
The process of grouping organism based on similarities; Classify because: Organize living things into smaller groups to make things easier to study, to make things easier to find, help avoid errors

Kingdom Descriptions
|
Animal - moves, doesn’t make own food.
Plant-Doesn’t move, makes own food Protist - some move, some make own food some don’t, most are unicellular Fungi - don’t move, doesn’t make own food Eubacteria - Prokaryotic, unicellular, auto or heterotroph Archaebacterica - Prokaryotic, unicellular auto/heterotroph |
|
|
Prokaryotic
|
an organism whose cells lack a nucleus and some other cell structure
|
|
|
Eukaryotic
|
an organism whose cells contain nuclei
|
|
|
How organism are classified (3)
|
cell type; number of cells in body; ability to make food
|
|
|
3 Domain System used in Taxonomy today
|
bacteria; archaea; eukaryc
|
|
|
Compare bacteria and eukaryc
|
unicellular, either auto or heterotroph and and prokaryotic
differ because of their chemical makeup |
|
|
4 Kingdoms of Eukaryc
|
protists, animal, plant, fungi
