Cells, the Three Domains & the Four Kingdoms

How are organisms classified into domains & kingdoms? p Cells n Organisms are placed

How are organisms classified into domains & kingdoms? p Cells n Organisms are placed into Domains based on their cell type n 2 types of cells p Eukaryotic § Cells have a nucleus § Nucleus – membrane covered organelle containing the cell’s DNA § Larger and more complex than prokaryotic cells § Has many organelles within the cell suspended in a fluid called cytoplasm

Cells continued n Prokaryotic Cells without a central nucleus p DNA is circular and

Cells continued n Prokaryotic Cells without a central nucleus p DNA is circular and free floating in the cytoplasm p Cells are much smaller than eukaryotic cells p Cells are much simpler containing no membranecovered organelles p 2 types p § Eubacteria – common today. Found everywhere § Archeabacteria – found in extreme environments

The 2 Domains of Bacteria are prokaryotic cells (do not have a nucleus containing

The 2 Domains of Bacteria are prokaryotic cells (do not have a nucleus containing DNA) p Domain Archea (also Kingdom Archea) p n n n p Been on Earth for 3 billion years Thrive in harsh environments such as: hot springs and hydrothermal vents Autotrophs – using chemosynthesis Heterotrophs Differ chemically from Eubacteria and in cell structure. Domain Bacteria (Kingdom Eubacteria) n n Eubacteria which include most bacteria Found nearly everywhere

Domain Eukarya Organisms in this domain have eukaryotic cells. p Eukaryotes are organisms with

Domain Eukarya Organisms in this domain have eukaryotic cells. p Eukaryotes are organisms with cells that contain nuclei. p There are 4 kingdoms within this domain p

Kingdom Protista Single celled or simple multicellular organisms p Eukaryotic cells p Evolved 2

Kingdom Protista Single celled or simple multicellular organisms p Eukaryotic cells p Evolved 2 billion years ago and are made up of all eukaryotes that are not plants, animals or fungi. p Can be animal-like, plant-like or funguslike in their characteristics p

Kingdom Plantae Usually green and can utilize the process of photosynthesis making them autotrophic

Kingdom Plantae Usually green and can utilize the process of photosynthesis making them autotrophic p Complex, multicellular organisms p

Kingdom Fungi Originally classified as plants, but do not do photosynthesis so eventually were

Kingdom Fungi Originally classified as plants, but do not do photosynthesis so eventually were placed in their own kingdom p Includes molds and mushrooms p Can be unicellular or multicellular p heterotrophs p

Kingdom Animalia Complex, multicellular organisms p Most can move and have nervous systems that

Kingdom Animalia Complex, multicellular organisms p Most can move and have nervous systems that help them sense and react to their surroundings p Cells lack cell walls unlike plants, fungi, bacteria, and most protists p Heterotrophs p
