-
Genetic diversity
- - The amount of variation in inherited traits between individuals of the same species.
- - ( how different these species will look in in the same large category of species
-
Taxonomy
- - This is the field that deals with classifying the estimated 10 million species here on earth.
- - Taxonomists have created artificial classification systems main system to deal with diversity with the goals of “ Identifying organism s”, Provide a basis for natural groupings of organisms
-
Who created the Binomial nomenclatur?
- - It was created by Carl Linnaeus.
- - This is a two part naming system that is assigned to an organism using Latin words.
- - system based on the organisms physical and structural features. ( bone) Believing that the more features organisms have in common the closer their relationship.
- -
-
What do these scientific names include.
- - They include the genus and species name of the organism. ( This is because the genus and species are the final classifications of the total 7 making them the most specific)
- -
-
How to write organisms names using the Binomial momenclature ?
- - The Genus name begins with a capital.
- - The species name begins with a lower case letter.
- - when the name is typed it is in italics.
- - Each word is underlined by itself separately.
- - The genus can be written alone but the species can never be used alone.
- - when two organisms share the same genus they related and if they don’t they are not closely related.
- -
-
Taxation facts
- - this is the process and science of naming living organisms.
- - Thus, in this industry scientific names are sometimes changed when the understanding and relationship changes.
- - It is possible for various species to be known by multiple scientific names.
-
What are the seven main levels of taxation in order ?
- - Kingdom
- - Phylum
- - Class
- - order
- - family
- - Genus
- - Species
- - The more down u keep moving the more specific you get
-
What are the 6 kingdoms ?
- - Fungi
- -Plantae
- - Animalia
- - Protista
- - Eubacteria
- - Archaebacteria
-
1 kingdom = Eubacteria
- - simple organism that do not have a nuclei ( prokaryotic)
- - they are heterotrophs or autotrophs
- - They are able to reproduce asexually ( Classic bacteria)
- - often have a cell wall
- eg bacteria , Cyanobacteria
-
Archaebacteria
- - These are prokaryotic
- - Heterotrophs
- - Live in salt lakes, hot springs, animal guts
- - contains cells walls
- - Thye are old bacteria that live in very extreme weather conditions.
- - eg. Mathogens, extreme thermophiles., extreme halophiles
-
Protista
- - most are single called but some are multicellular
- - Eukaryotes
- - both autotrophs and heterotrophs and reproduce sexually and asexually
- - live in aquatic or moist environment
- eg absent algae, Protozoa
-
Fungi
- - most are multicellular
- - all are heterotrophs
- - reproduce sexually or asexually
- - most are terrestrial and contain cells walls
- eg. Mushrooms, yeast, bread moulds
-
Planate
- - all are multicellular
- - all are autotrophs
- - reproduce sexually and asexual
- - most are terrestrial and contain a cell wall
- - mosses ferns, flowering plants
-
What is a phylogeny?
- - This is the history of the evolution of organisms.
- - It is showcased as a phylogenetic tree
-
Dichotomous key
- - They use when classifying organisms
- - this key gives instructions in pairs of statements.
- -
-
Prokaryotic vs Eukaryotic
- Pro
- - it has no nucleus and is just the class kcal bacteria and follows into the kingdoms known as Archaea or bacteria in general
- Eu
- - They have a nucleus
- Kingdoms that fall into this category are Fungi , Animals, Protists, Plants
