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

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

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)

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

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
