1. Kingdoms
Life science

2. Classifications Scientists classify organisms into 6 kingdoms
When dividing organisms into kingdoms, scientists consider the organism’s cell type, cell structure, body form, and whether it is an autotroph or heterotroph

3. How they get food
Autotroph – organism that uses energy from sunlight to produce its own food; usually plants
Heterotroph – cannot produce its own food; uses organic carbon for growth

4. Kingdom Eubacteria • unicellular bacteria (one celled)
• prokaryotic – no nucleus
• thick cell walls
• some are autotrophs, some are heterotrophs
• classified by shape: cocci, bacilli, sprillia

5. Kingdom Archaebacteria -
• unicellular bacteria (one celled)
• prokaryotic – no nucleus
• some are autotrophic, some are heterotrophic
• live in extremely harsh environments; salt water and hot springs

7. Kingdom Protista • Eukaryotes (cells have nucleus)
• Mostly unicellular
• Some are heterotrophs
• Some are autotrophs
• Examples amoeba, Paramecium

8. Kingdom Fungi • Heterotrophs
• Most fungi get their food by breaking down dead organic matter
• Mushrooms(multicellular) and Yeasts (unicellular

9. Kingdom Plantae • Plants are all • Produce Oxygen • Have a cell wall
o Multicellular
o Autotrophic (chloroplasts)
• Produce Oxygen
• Have a cell wall
• Come in a wide variety of shapes and sizes

10. Kingdom Animalia • Multicellular and Heterotrophic
• Eat plants and/or other organisims
• Come in a wide variety of shapes and sizes
• No Cell Wall or Chloroplasts
