CLASSIFICATION OF ORGANISMS THE 6 KINGDOMS
Kingdom Bacteria • Where are bacteria found? • Members of this kingdom are found in soil, water, and other living things
Kingdom Bacteria • All bacteria are single celled organisms that do not have a nucleus! • What do we call organisms with these characteristics? • Bacteria have cell walls Prokaryotic
Genetic material Cell Membrane
Kingdom Bacteria • Bacteria can be one of three main shapes. • Rod-shaped (bacilli) • Spherical-shaped ( cocci) • Spiral-shaped (spirilla)
Kingdom Bacteria • Reproduce by Binary Fission • one bacteria duplicates its genetic material and then splits into 2 separate cells • the new cell is identical to the parent
Kingdom Bacteria • Some bacteria reproduce sexually through conjugation • Two parents • Transfers some of its genetic material • Offspring are genetically different from parents
Kingdom Bacteria • Different types of bacteria are classified by how they get their food • Autotrophic • Heterotrophic • Decomposers
Kingdom Bacteria • Roles/Uses • 99% of bacteria are helpful to humans • Produce foods such as cheese, apple cider, and sauerkraut • Some can even clean up oil spills and gasoline leaks • Bacteria cause food to spoil • Some are decomposers
Can Bacteria Help Us? • Bacteria help us • Digest food • Make vitamin K
Kingdom Archaebacteria • Where are archaea found? • Most organisms in this kingdom are found in extreme environments, such as hot springs • Can be found in ponds and swamps • Most archaea prefer environments with little or no oxygen
Kingdom Archaebacteria • All archaea are prokaryotic organisms • They reproduce using binary fission
Kingdom Archaebacteria • There are 3 main types of archaea • Heat Lovers—live in extremely hot water like that found in ocean vents and hot springs • Salt Lovers-- live in environments with high levels of salt (ex. Dead Sea and Great Salt Lake) • Methane Makers—live in swamps and animal intestines; give off methane gases
