- Classification
- Keywords
- Morphology- the physical appearance of an organism
- Taxonomy- classification of living organisma
- Homologous features- morphological trait shard by different organisma
- Classification- categorisng natural objects
- Taxon- the hierarchical groups used in classification
- 7 levels of classification (KPCOFGS) Genus and species = binomial name of organism
- 5 kingdoms
- Fungi
- Eukaryotic, non cellulose cell wall, no chloroplasts or photosynthesis, organelles and nuclear envelope, HETEROTRO-PHIC
- Animal
- Eukaryotic, multicellular, true nuclues, no cell wall or chloroplast- HETEROTRO-PHIC (energy from organic molecules)
- Prokaryote
- No true nucleus or nuclear envelope, no membrane bound organelles, smaller ribosomes, peptidoglycan cell wall, plasmid (small circular DNA molecule)
- Plant
- Eukaryotic, multicellular, organelles etc same as animal but with cellulose cell wall and chloroplasts, AUTOTROPH-IC (energy from combining light energy with CO2 for sugar in photosynth..)
- Protoctist
- Eukaryotic, single celled, HET/AUTOTR-OPHIC like plant and animal variable features
- Fungi
- To avoid convergent evolution (classifying organisms with irrelevant homologous features) we have 3 DOMAINS, comparing organisma DNA instead of morphology
- Bacteria- no nucleus
- Archaea (bacteria like), cell membrane, flagella, extreme environments, transcription+ translation
- Eukarya (animals, plants, fungi)
- Keywords
