DQ # Write a paragraph (at least four sentences) explaining how you organize your clothes. • Example of topic sentences: I have my own system of organizing my clothes. I organize my clothing by…
Organism • Characteristics that all living things have in common. • Has cells or a cell • Uses Energy • Reproduce • Made of the chemicals of life (DNA) • Respond to change • Grow & Develop
Organisms come in a wide range of variety!
Prokaryotic Cells vs. Eukaryotic Cells • Prokaryotic: do not have a nucleus -DNA not bound • Eukaryotic: have nucleus -DNA bound in the nucleus
The Six Kingdoms 6 Kingdoms
Archaebacteria • Archeologist- Studies old things • Archaebacteria is the oldest bacteria on earth • Found in extreme environments • One celled- unicellular • Prokaryotic cells- no nucleus • Microscopic- can’t be seen w/o equipment
Archaebacteria • About 3.5 billion years old • EX: hot springs and swamp • Reproduce asexually • Leastcomplex
Three Major Types of Archaebacteria: Methanogens (Methane-producers)- responsible for methane gas. (Smelly) Thermophiles- Live in HOT springs and black smokers (under water heat vents) Halophiles- Live in saturated brine and salt water. (Dead Sea)
Eubacteria • Most common bacteria • Found on YOU and in YOU and YOU eat it, causes YOU to get sick. • Prokaryotic cell- NO nucleus • Unicellular • Microscopic • Most are heterotroph (consumers)- have to eat
Decomposer-Vocab • Most are decomposers- help break down dead organisms. • Examples of other decompsers: Bacteria, Mushrooms, Athlete’s feet
Eubacteria • Ex: found in your intestines, helps make vitamin K, Sour crout, Strep throat, Eboli • Reproduce asexually
Protista • Most are unicellular • some are multi-cellular • Some are heterotroph, some are autotroph • All have eukaryotic cells- cells with a nucleus
Some are microscopic & some are large • Most reproduce asexually, some sexually • Ex: seaweed, slime mold, paramecium, & amoeba
Protista • Sometimes called the Junk drawer or misfits.
Protista • Most reproduce asexually, some reproduce sexually. • Remember: Unicellular usually reproduce asexually • Multicellular usually reproduce sexually
Fungi • Most are multi-cellular • Only one unicellular (yeast) • heterotrophs decomposers • Called the Recyclers of Earth • Eukaryotic cells- has a nucleus • Ex: mushrooms, bread mold, yeast, athlete’s foot • Most reproduce Sexually (spores) • Some asexually
Kingdom Plantae • Autotrophs- make their own food • Eukaryotic cells • Allare multi-cellular • Have chlorophyll in their cells allows the plants to make their own food • Ex: trees, roses, water lily • Most reproduce sexually (pollen), some asexually
Animalia • All multi-cellular • All heterotroph • Have Eukaryotic cells- (have a nucleus) • Most complex organisms on earth • Ex: pig, dog, cat, insects, humans • Most reproduce sexually • Youngest on Earth
Each kingdom can be broken into smaller groups based on shared characteristics
Prokaryotic Archaeabacteria Eubacteria No Nucleus
Eukaryotic Has Nucleus Animalia Protista Fungi Plantae
All 6 Kingdoms can be placed in one of the three domains: • 1. Archaea • 2. Bacteria • 3. Eukarya
Domains Archaea Bacteria Eukarya Protists Fungi Plantae Animalia Eukaryotes Eubacteria Prokaryotes Archaebacteria Prokaryotes Has a nucleus No Nucleus No nucleus
Archaea Domain • Unicellular • Asexual • Prokaryotic • Old • Kingdom: Archaebacteria
Bacteria Domain • Unicellular • Asexual • Most are heterotroph • Most common bacteria • Kingdom: Eubacteria
