Notes

Characteristics for life:move, air, water, nutrition,respond to change, produce waste, grow older, reproduce.Mammals have skin with hair or fur, constant body temp example human. Birds have feathers, constant body temperature example emu. Fish with cartilaginous skeleton found in water, changing body temp example shark.Reptiles have scales,changing body temp example snake.Amphibia changing body temp example frog.Fish with a bony skeleton changing body temp example goldfish.Jawless fish no fins example lamprey.Placental are well developed when born example mice.Marsupials babies carried in pouch example koala. Monotreme young feed on milk example platypus. Invertebrate: Platyhelminths have flat body example tapeworm. Arthropods found in land and water, segmented bodies examples spider. Poriferans found in water example bath sponge. Annelids found in water example leech. Cnidarians tentacles example jellyfish.Nematodes live in water example threadworm. Echinoderms example sea urchin.Molluscs soft body example snail.Gymnosperm(conifers) found on land, true roots example cedar. Angiosperms(flowering plants) found on land,produce flowers, true roots example fruit tree.Bryophytes found damp places, rootlike structure example moss. Pteridophytes(ferns) found in moist areas, proper roots and stems example tree fern. Algae live in water, unicellular, no true roots, stems example euglena.Fungi no true roots, stems usually multicellular example yeast. Lichens no true roots, stems,leaves.Cells:Light microscope has limited visible detail but prepared quickly. Electron have high magnification but only dead section can be viewed. Nucleus control center. Prokaryotes have a nucleus with a membrane. animalia: multicellular, nucleus with membrane.Fungi usually multicellular, nucleus with membrane, cell wall.Plantae: most multicellular, nucleus with membrane, cell wall, vacuole, chloroplasts. Monera: unicellular,cell wall,chloroplasts in some, Protista: unicellular, membrane, cell wall in some, large vacuole in some, chloroplasts in some.Membrane controls what goes in and out of cell. Cytoplasm transfer energy, stores food.The cell wall provides protection.Organelles are found inside cytoplasm of eukaryotes. Includes mitochondria which supplies energy. Vacuole contains watery fluid. Stores water and dissolved substances.Unicellular does all jobs by itself.Reproduces by cell division.Multicellular are filled with cells which do different jobs. Reproduction and repair involve cell division. Micrometre is 1 millionth of a metre. Plant cells contain cell wall, cell membrane, vacuole, cytoplasm, nucleus, chloroplasts. Viruses are nonliving. Reproduce by invading cell. Don't have a membrane or cytoplasm. Have protein box containing nucleic acid. When inside a cell virus's act as if they are alive. Viruses are smallpox, ebola.
