1.1. Characteristics

1.1.1. Single celled

1.1.2. No organelles with membranes

1.2. Archaebacteria

1.2.1. Characteristics Lives in extreme conditions May not contain oxygen

1.2.2. Methanogens

1.2.3. Thermophiles

1.3. Eubacteria

1.3.1. Morphology Bacillus Cholera Rod shaped bacteria Coccus Spherical shape Lactobacillus sp. Spirillum Spiral Spirillum minus

1.3.2. No mitochondria nor chloroplast

2. Eukaryote

2.1. Fungi

2.1.1. Characteristics Must absorb energy Reproduce through spores Sexual & Asexual Not motile Cell walls composed of chitin

2.1.2. Phylas Zygomycota Common Mould Ascomycota Yeast, Truffles, Morels Basidiomycota Mushrooms, Club Fungi Deuteromycota Parasitic Fungi, Pennicillum, Athletes foot Chytridiomycota Chytrids

2.2. Plants

2.2.1. Characteristics Multicellular Photosynthetic Develop from Embryos

2.2.2. Phylas Bryophytes Mosses, liverworts, hornworts Non - vascular Gametophyte is dominant in the life cycle Lack vascular tissue Found in moist regions Seedless Vascular Ferns Vascular tissue Found in moist regions Sporophyte is dominant Gymnosperms Have naked seeds Sporophyte makes male & female cones Angiosperms Flowering plants Sporophyte is dominant Reproduction happens within the flower Gametophytes are microscopic

2.2.3. Transition for Aquatic Environments to Terrestrial Environments Tubes to transport water and nutrients up the stem (Phloem and Xylem) Growing towards the sun, giving the plant an upright position Developed reproductive skills Formed wax, cuticles and stomata to avoid the lost of moisture

2.3. Animal

2.3.1. Characteristics Multicellular Motile Heterotrophic Develops from embryos

2.3.2. Phylas Porifera Asexual & Sexual Filter water to retrieve energy Sponges Cnidaria Symmetrical Anemone, Jellyfish, Coral, Hydra Two body forms Gastrovascular cavity Two tissue layer Nematocysts (may sting) Nematoda Bilateral symmetry Centralized nervous system Three tissue layers No body cavity, circulatory system nor hard skeleton Annelids Earthworm, Leech, Polychaete Have repeating units Digestive tract Closed circulatory system Coelom Arthropods Crustacean Chelicerates Uniramia Characteristics Molluscs Characteristics Gastropod Cephalopod Bivalves Chordates Characteristics Urochordate Cephalochordata Vertebrates

2.4. Protist

2.4.1. Characteristics Found in moist or aquatic regions Unicellular (Some are multicellular) Capable of motion Many different structures Posses both plant & animal characteristics

2.4.2. Phylas Plant Like Euglenoids Characteristics Animal Like Sporozoan Zooflagellates Ciliates Rhodophyta Sarcodines Fungus Like Characteristics

2.4.3. Eating Strategies Heterotrophic Receives energy from other resources Autotrophic Creates own energy
