COS # 4:Describe organisms in the 6 kingdom classification system by their characteristics Mrs. Jackson 7th grade Life Science The Six Kingdom Classification System • Prokaryotes: Contains no Nucleus – Archaeabacteria – Eubacteria • Eukaryotes: Contains a Nucleus – Protista – Fungi – Plantae – Animalia Archaebacteria • The prefix “ARCHAEA” means ANCIENT. They are considered ancient because they probably resembled the FIRST FORMS of life on Earth • Live in very harsh environments Archaebacteria: Environment • Can live where no other organism can survive • They live in extreme environments such as acidic hot springs, near undersea volcanic vents and highly salty water Archaebacteria: Characteristics • First organisms on Earth • Eats nutrients just like any other single celled organism • Obtain food by absorption WRAP UP: 3-2-1: • List 3 characteristics of archaeabacteria • 2 things you want to know about archaebacteria • 1 thing you already knew about archaebacteria Eubacteria • It is the eubacteria that most people are talking about when they say bacteria, because they live in more neutral conditions Eubacteria: Environment • They are all around • Just about anywhere there are bacteria • They are the ones in your toilet Eubacteria: Major Characteristics • All eubacteria are unicellular • Are microscopic • Some can make their own food (autotrophs) while others rely on external sources of nutrition (heterotrophs) • Has a cell membrane • Eats dead things Protista • Protists include many widely ranging microbes including; slime molds, protozoa, and primitive algae Protists: Characteristics • Mostly eukaryotic and unicellular • There are animal like, fungus like, and plant like protisits • Some are beneficial • Some protists cause disease • Can move when it wants to • Can be autotrophs or heterotrophs Protists Locomotion • 3 Types of Movement: – Pseudopod (false foot) – Flagella/Cilia – Contractile vacuoles Protists: Environment • • • • • Fresh water Marine water Snow Damp soil Polar bear hairs Fungi • Includes some of the most important organisms • By breaking down dead organic material, they continue the cycle of nutrients through ecosystems Fungi: Characteristics • • • • All fungi are eukaryotic They can All fungi have a cell wall May be unicellular or multicellular Fungi • Can be very helpful and delicious • Many antibacterial drugs are derived from fungi Plantae (Plants) • All plants are multicellular autotrophs that have a cell wall Plants: Facts • Prokaryotic / eukaryotic • Food consumption: photosynthesis (absorbs light) • Reproduction: both sexual and asexual • Environments: land and water Three features distinguish Plants from animals • Plants have chlorophyll, the green pigment necessary for photosyntheis • Their cell walls are made sturdy by cellulose • Plants are fixed in one place (they don’t move) Animalia (Animal) • • • • All animals are multicellular All animals are heterotrophs Lack a cell wall Capable of movement at some point in their lives Animalia • To be an animal requires that an organism eat its food and reproduce mainly by sexual means • The animalia kingdom is divided into two groups: – Vertebrates – Invertebrates
