  1. Note for C 1.1: Single-celled organisms have all the characteristics of living things

  2. Living things come in many shapes and sizes. • Six Kingdoms (main groups of organisms) • Archaea • Bacteria • Protists • Fungi • Plants • Animals

  3. Living things share common characteristics. • Cellular organization (unicellular/multicellular) • Grow: consume food, build structures, and repair or replace worn-out structures • Respond to changes in environment • Reproduce • Make more of themselves • Single cell organisms reproduce by binary fission (offspring consist of 2 identical cells)

  4. Living things need energy, materials, and living space. • Food supplies an organism with energy it needs to move, grow, reproduce, and respond • Water is an ingredient in many cellular reactions, provides structure, and watery environment that cells need. • Viruses are not alive—contain genetic material surrounded by a capsid, cannot respond or gro, not as complex as cells

  5. Vocabulary • microorganisms—very small organisms • Kingdoms—6 major groups into which organisms are divided • Binary fission—genetic material from one cell is duplicated and broken apart into 2 identical cells (daughter cells) • Virus—a small collection of genetic material surrounded by a protein coat, less complex than a cell
