  1. Organization of Matter What levels are there?

  2. Levels of Organization Sub-atomic Particles: Make up atoms Ex.Quarks, Leptons make up Electrons, Neutrons, Protons Atoms: Smallest whole unit of matter Ex. Elements like Hydrogen, Helium, Oxygen, Carbon Molecule: 2 or more atoms, not necessarily the same Ex. Nitrogen gas (N2), Water (H2O), Salt (NaCl)

  3. Levels of Organization Continued Macromolecules: Organic molecules that make up most living things Ex. Proteins (meat, beans, enzymes), Lipids (fats oils, waxes), Carbohydrates (sugars, starches), Nucleic Acids (nucleotides) Organelle: Organized structure in a cell, cell parts Ex. DNA, RNA, Cell membrane, Nucleus, Chloroplast

  4. Levels of Organization Continued Cell: Smallest living unit, can also be ORGANISM Ex. Eukaryotic (Plant, liver); Prokaryotic (bacteria) Tissue: Several cells with common job Ex. Muscle, bone, nervous tissue Organ: Several tissues that have one or more jobs that make up a separate part of the body Ex. Heart, Lungs, Brain, spleen

  5. Levels of Organization Continued Organ system: One or more organs working togetherfor general function Ex. Digestive, nervous Organism: Unique individual/ Living thing Ex. Human, Oak tree, Mouse, Bacteria, Paramecium

  6. Levels of Organization Continued Population: All individuals of 1 species in an area Ex. Herd of elephants, Gaggle of geese, Pack of wolves Community: All living things (organisms) in one area Ex. Living organisms in forest, plain Biome: Living and non-living factors in fixed area Ex. Amazon Rain Forest, Sahara Desert

  7. Levels of Organization Continued Ecosystem: All living and non-living factors in a geographic type (all biomes of same type) Ex. Taiga, Tundra, Desert Biosphere: All living environments on Earth Ex. Earth (as far as we know) Gaia?

  8. Levels of Organization Beyond Biology Solar System: Sun, all planets, dwarf planets, plus Kuiper belt Galaxy: All solar systems in fixed array Ex. Milky way (ours), Andromeda Universe: All know material from Big Bang Ex. Everything known to humanity
