Kingdoms Life science

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

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

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

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

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

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

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

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
