Animals.

Animals

  • multicellular, eukaryotic, heterotrophs.
  • All living organisms can be sorted into one of two groups depending on the basic structure of their cells. These two groups are called the prokaryotes and the eukaryotes.
  • They feed on other living things.
  • they are usually subdivided into groups such as carnivores, herbivores, carnivores and parasites.

  • 1.) Phylum Chordata
  • 2.) Phylum Cnidaria
  • 3.) Phylum Ctenophora
  • 4.) Phylum Platyhelminthes
  • 5.) Phylum Nematoda
  • 6.) Phylum Brachiopoda
  • 7.) Phylum Mollusca
  • 8.) Phylum Annelida
  • 9.) Phylum Arthropoda

The Puma (Puma concolor)
Part of the Chordata Phylum, it is an animal with a vertabrate. It lives mainly in the western hemisphere, found mostly in the United States and South America. It moves around on four legs and is a carnivore. It reproduces externally and the species consist of two genders. They are generally loners and tend to only come together in small groupings.

Protists.

Protists
  • eukaryotic, more than 200,000 species 3 main groups 1. animal -like 2.plant-like 3. fungus-like.
  • a diverse group of eukaryotic microrganisms.
  • plant-like.
  • autotrophs, photosynthetic.
  • euglena, diatoms, phytoplankton.
  • algae: red, golden. green(volvox), brown(kelp). 
  • animal-like.
  • heterotrophs or parasites.
  • paramecium, stentor, amoeba.
  • harmful = cause malaria and sleeping sickness.
  • fungus-like
  • feed on decaying matter.
  • absorb food through cell walls.
  • some are parasites.
  • slime molds and water molds.
  • water mold caused the irish potato famine in the 1840s.

Archaeabacteria.

Archaeabacteria
  • cell walls = NO peptidoglycan.
  • some are heterotrophs, some aare autotrophs.
  • live in extreme enviorments: hot springs, salty lakes.etc.
  •  a group of singel-celled microorganisms. A single individual or species from this domian is called an archaeon sometimes spelled archeon. They have no cell nucleus or any other membrane-bound organelles within their cells.
  • found in habitats including soils, oceans etc.
  • archaeabacteria is unicellular.
  • it obtains its energy through photosynthesis.
  • it moves by its flaggella
  • it reproduces asexually

life science.

EUBACTERIA
  • prokaryotic domain of life with a set of characters that unite its extraordinarily diverse taxa. 
  • cell walls = peptidoglycan.
  • some need oxygen, some dies with oxygen.
  • some are heterotrophs, some are autotrophs.
  • most abundant organisms on earth.
  • eubacteria is unicellular.
  • usually found in everything.
  • eubacteria obtains energy by breaking down dead animals and organisms.
  • eubacteria is not harmful.
  • asexual.
