Classification

Two systems to classify organisms 

Natural- based on evolutionary links, organisms grouped together if they have common ancestry.

Artificial- based on visible features, groups of organisms easier to identify ( e.g. All yellow flowering plants could be grouped together) 

CLASSIFICATION= The grouping process of all living things

There are 5 KINGDOMS 

Kingdom                 E.G.

Plants                    Flowers, mosses, grasses

Animals                 Fish, insects, humans 

Fungi                     Mushrooms, toadstools, yeast

 Protoctista             Amoeba, algae

Prokaryotes           Bacteria 

Problems with Classification 

Hybrids -  Individuals from closely related species can breed= produce hybrid- mostly infertile ( unable to breed)

-------------------------

Bacteria- unusal ( asexual organisms) 

Many species of bacteria- do not reproduce with each other- reproduce asexualy- classed as different speicies bases on chacteristics.

-------------------------

Constant evolution

Evolution- organisms slowly changing, enventually become new species
