Kingdoms of Living Organisms All organisms on The Earth belong to one 
of the following kingdoms.  Bacteria  Archaea  Protist  Fungi  Plant  Animal

Organisms on Earth Unicellular- Multi-cellular- one celled organisms ex- bacteria archaea most protists some fungi   Multi-cellular- more than one cell in the 
organism plant animal some protists most fungi Review: Prokaryotic - does not have a membrane around a true nucleus Eukaryotic - does have a membrane around a true nucleus

Unicellular Organisms: Bacteria - smallest known cells lives everywhere (more in your intestines than people on Earth!) no nucleus or membrane-covered organelles cell wall and cell membrane reproduces asexually (binary fission) Archaea - similar to bacteria ribosomes, cell wall, & cell membrane 
are different than other cells most live in extreme environments 
(deep in oceans, swamps, hot springs)

Amoeba- One-celled organism lives in fresh water porous cell membrane eats bacteria pseudopods (foot-like 
structures) help change 
its shape reproduces asexually 
(binary fission) Kingdom - Protist Yeast - Type of fungi Often found on plants leaves and flowers; 
soil and salt water; skin surfaces and 
intestinal tracts reproduces by dividing (asexual -- budding) used for fermentation (baking and alcoholic 
industries)

Fungi - includes moulds, yeasts, rusts, 
smuts, mildews, mushrooms, and 
toadstools not considered plants: no leaves 
or roots, no chlorophyll, cannot make 
own food some are poisonous live and feed on other organisms 
(living or dead) reproduce sexually and asexually

Multi-cellular Organisms Plants - made of many cells with different structures have cell walls and chloroplasts photosynthesis - process of how plant take in 
sunlight to create sugars (food) includes organisms such as trees, herbs, 
bushes, grasses, vines, ferns, mosses, algea reproduces both asexually and sexually 
depending on species Animals - multicellular most can move spontaneously and independently all are heterotrophs--must take in food by 
eating other organisms classified as Invertebrates (no backbone) or Vertebrates (has a backbone) 98% of animals are classified as invertebrates reproduces both asexually and sexually

Advantages of Being Multicellular Larger Size  Fewer Predators because they are larger  Have a larger variety of prey they can eat Longer Life  Organism is not limited to the life span of one cell   Specialization  Each type of cell has a particular job  Makes the organism more efficient  Example: The cardiac muscle cell is a specialized muscle cell and makes the heart beat
