Presentation Transcript

  1. Domains • The 3 Domains are Archaea, Eubacteria and Eukaryota (Eukarya) • Each Domain includes 1 or more Kingdoms • Domains are bigger than Kingdoms • Archaea = Archaebacteria • Eubacteria = Eubacteria • Eukaryota = Animals, Plants, Protist, Fungi

  2. Autotrophs • Organisms that can make their own food are called autotrophs • They use photosynthesis to make sugar using the molecule chlorophyll • Examples: Plants, Some Protists (algae, euglena), Cyanobacteria (blue-green bacteria)

  3. Heterotrophs • Organisms that use other organisms as a food source are called heterotrophs • Some obtain food by eating plants (herbivores) • Some get their food by eating other animals (carnivores) • Some eat plants and animals (omnivores) • Examples: Animals, Some Protists (amoeba, paramecium), most Eubacteria

  4. Plants • Multicellular and Eukaryotic • Use Photosynthesis (autotrophs = make their own food) • Reproduce by seeds or spores. (sexual or asexual) • Have rigid cell walls and chloroplasts

  5. Invertebrates • Animals that do not have a backbone are called invertebrates. • They generally have simple or basic body systems. • Insects have hard exoskeletons, but do not have bones. • Examples: Lady bugs, spiders, lobsters, snails, sharks

  6. Vertebrates • Animals that do have a backbone are called vertebrates. • The bones in the spine are called vertebrae. • They also have other bones to aid in movement and to protect organs. • They generally have complex body systems. • Examples: Humans, cats, dogs, birds, deer, any animals with backbones

  7. Animals • Members of the animal kingdom are multicellular and eukaryotic • They get energy by eating other organisms. They are heterotrophs. • They are divided into 2 groups: Vertebrates and Invertebrates. • Animal cells have a cell membrane, but not a cell wall • Animals reproduce sexually. • Carnivores eat animals • Herbivores eat plants • Omnivores eat animals and plants

  8. Reproduction • Reproduction is the process of making more of one organisms own kind. • Reproduction is necessary for the survival of a species. • There are two forms of reproduction: Asexual and Sexual.

  9. Asexual • Asexual reproduction occurs without a sperm and egg. • It involves only one parent. • Usually a cell splits to make two identical copies of itself. • Common in one celled (unicellular) organisms

  10. Sexual • Sexual reproduction occurs when a sperm and egg unite. • It involves two parents. One male and one female. • Offspring get genetic information from both parents. • Common in multicellular organisms.

  11. Fungi • Can be single celled or multi celled • Fungi reproduce by spores through asexual reproduction. • Get their energy by feeding on other organisms, alive or dead! • They do not have chlorophyll, so they can not make their own food. • Many fungi are decomposers • Examples: Mold, Mushrooms, Yeast

  12. Protists • Can be singled celled or simple collections acting as a multi-celled organism called colonies • Are eukaryotic (have a separate nucleus with a membrane) • Some are autotrophs and some are heterotrophs • Some reproduce asexually and some reproduce sexually • Examples: Amoeba, paramecium, algae, euglena

  13. Archaebacteria • Archaebacteria are single celled • They are prokaryotic • They reproduce asexually • They live in extreme environments, like hot springs, volcanic vents, very salty water, but can be found in other places also • Some make their own food (autotrophs) and some feed on other organisms (heterotrophs)

  14. Examples http:youtu.be/N-EYTtxsL8g// Drawing of bacteria mats on sides of an underwater volcanic vent feeding on the methane gas Near the edges of a geyser pool with bright colors

  15. Eubacteria • Single celled and prokaryotic • Some need oxygen to live. Some die from oxygen • They reproduce asexually • Most feed off of other organisms (heterotrophs) • Live in soil, water and other living things • Cyanobacteria use photosynthesis • Most familiar bacteria are eubacteria

  16. Examples of Eubacteria E. coli on lettuce (helps digest food, can cause food poisoning) Lactobacillus bulgarus (1 type of bacteria in yogurt) streptococcus (causes strep throat)
