Taxonmy Flashcards
Hy do we need a classification system?
We need one because:
1) we need to be able to identify and name organisms so it is easier to study
2) and to see the relationships the organisms have with their kingdoms
Who was c Linnaeus
He was famous of his work in taxonomy. He developed one of the first systems of classification, the system that was used was known as a bio nominal nomenclature consists of a two word naming system. (Genus, species) the system was based upon structural and physical features, the more features they had in common the closer the relationship.
What is taxonomy?
It is the science of classifying organisms
Why is a bionominal nomenclature
A method of naming organisms
7 levels of classification are:
Kingdom Phylum Class Order Family Genus Species
Classification for humans
:
Kingdom-animalia Phylum-Chordata Class- mammalia Order-primates Family-hominidoe Genus - Homo Species-sapiens
What are the 6 kingdoms
Animalia Plantae Fungi Protista Archaebacteria Eubacteria
Describe animalia
These organisms are eukaryotic, reproduce sexually, are multicellular and are heterotrophic. They lack a cell wall and can live on land or In water. Examples are starfish, humans, dogs etc….
Describe plantae:
These organisms are multicellular and eukaryotic, they are ALL autotrophic and some live in aquatic ecosystems but most can be found on land. They are sub-divided into vascular and non vascular. These organisms reproduce asexually and sexually.
Examples are Mosses, ferns, trees etc….
Can transport fluids through their structures (ferns)
Vascular
Can not transport fluids through there structures
Non vascular
Describe fungi:
These organisms are heterotrophic, they are eukaryote parasites and decomposers. Fungi are mostly multicellular they are also found everywhere. The can reproduce asexually and sexually. Examples are mushrooms, yeast, and moulds.
Describe Protista:
These organisms are eukaryotic, some are multicellular but most are unicellular. Some act as plants and some act as animals so they are both autotrophic and heterotrophic. They can reproduce both ways. Some examples are algae, euglena, ameba
Describe archaebacteria:
These organisms are prokaryotic, produce asexually are heterotrophic and are unicellular. These types of bacteria can thrive in the harshest of environments, hot springs, polar ice caps and salt lakes. Some examples are halophiles thermophiles methanogens.
Describe eubacteria:
These organisms are the most abundant in the earth. They are prokaryotic and unicellular. They can be heterotrophic and autotrophic. The reproduce asexually.
Some examples of these organisms are : e. Coli, Cyanobacteria, blue green algae
