- Classification
- Kingdoms
- Prokaryotae
- Unicellular organisms like blue-green algae and bacteria
- They have internal cell membranes and so no ERs, nuclear membrane, golgi body ETC
- They have a cell wall but it isn't made of cellulose
- Protoctista
- Mostly small eukaryotic organisms that didn't fit anywhere else.
- They have membrane bound organelles like a nucleus
- Fungi
- They are made of a network of fibers called hyphe and then these come together to make mycelium
- Cell wall is made of chitin
- They have no photosynthetic tissues and feed hetrotorphiclly, so they feed on other things
- They reproduce via spores
- Plantae
- These are plants.... They are larger multicelluar organisms that produce sugar via photosynthysis
- The cells are plant cells, with a cell wall, a vacuole containing cell sap and chloroplasts filled with chlorophyll to photosynthyse
- Animals
- Advanced multicellular organisms that are hetrotophic as well as lacking a cell wall
- Have a nervous system
- It consists of two main groups, chordates and non-chordates (vertebrates and invertebrates)
- segmented worms etc are non-chordates and fish and reptiles are chordates
- Prokaryotae
- Levels of classification
- Kingdom
- The largest grouping, e.g. plants and animals
- Phylum
- Groping of classes that share common features
- Class
- A grouping of similar orders, e.g. Insecta
- Order
- Grouping of similar famlies e.g. orthoptera, consisting of locusts and crickets
- Family
- A grouping of similar genera (plural genus)
- Genus
- A group of species that are very closely related e.g. Locusta
- Species
- A group of species that share a large number of common characteristics and can successfully interbreed to produce fertile offspring
- ***** Prostitutes Can Offer Fantastic *********
- A taxon is a level of classification
- Kingdom
- Ordering different animals into manageable groups
- Taxonomy is the study of the diversity of living organisms and these are the people who group species
- You develop the name of an animal based on it's generic name (Genus) and its specific name (Species) and the international language for this is latin
- Kingdoms
