Classification defination |
The process of sorting organisms into groups based on their similarities and differences. |
|
|
|
Definitions: Taxonomy Phylogeny |
Taxonomy= The study of classification Phylogeny=study of evolutionary relationships between organisms Classification produces a hierchy of taxonomical groups |
|
|
|
Phylogeny |
The idea that species are all related to a common ancestor |
|
|
|
Evidence for specie relationships |
Behavioural Anatomical Embryilogical;growth from the anus outwards(humans) or mouth outwards. Molecular;-protiens, DNA |
|
|
|
How species are classified |
Domain (3) Splits into 5 kingdoms Which branch off into Phylum Class order Family Genus |
|
|
|
Humans classified as? |
Binomial Genus=Homo Species name=sapiens Notice species does not have capital letter and genus does Always write the binomial name in italics and underline it!! |
|
|
|
How many domains? |
3 |
|
|
|
Names of domains |
Eukaryotae Bacteria(eubacteria) Archaea (archaeabacteria) |
|
|
|
Molecular Evidence that Archaea and bacteria are different? |
RNA polymerase(used to replicate dna in bacteria) is different in Archaea and bacteria- this is known as molecular evidence Further evidence is that they have different histone(alkalineprotiens) |
Do not confuse RNA polymerase with dna polymerase! |
|
|
Cell membrane evidence for difference between Archaea and bacteria? |
-different lipid bond -different development/composition of flagella |
|
|
|
How many kingdoms? |
5 |
|
|
|
5 kingdoms |
Prokaryotae Anamalia Prototista Fungi Plantae |
|
|
|
Prokaryotae |
- (Before) without nucleus Loops of naked dna No membrane bound organelles Smaller ribosomes(18um) Respiration occurs on the cell membrane Smaller cells(30micrometre) Peptidoglycen cell wall |
|
|
|
Protocista |
Eukaryotic(membrane bound organelles) Single celled Free living Live in water Seen as outcast of the classification system as they just don't classify as any other specie |
|
|
|
Fungi |
Eukaryotic Mycelium consisting of hyphae (related to athletes foot and ring worm) Chitin cell wall Multinucleate cytoplasm Free living Saprotropic/hecrotrophic-live on decaying matter or take food from organisms. Spore reproduction. |
|
|
|
Plantae |
Cellulose cell wall Eukaryotic Multicellular Chloroplasts Autotrophic-produce own food from photosynthesis |
|
|
|
Anamalia |
Eukaryotic Multicellular Heterotrphic Fertilised egg that develop into a blastula-ball of cells. |
|
|
|
Heterotrphic Saprotrophic |
Saprotrophic-live on decaying matter Heterotrphic-rely on other organisms from food |
