Organization of
Matter
What levels are
there?
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)
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
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
Levels of Organization Continued
Organ system: One or more organs working together
for general function Ex. Digestive, nervous
Organism: Unique individual/ Living thing
Ex. Human, Oak tree, Mouse, Bacteria, Paramecium
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
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?
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
