*PROTISTS*
SUMMARY
A protists is any of a group of eukaryotic organisms belonging to the kingdom Protista according to some widely used modern taxonomic systems.

*MAJOR GROUPS*

Animal-like Protists:
  • Their decomposer's and symbiotic, are disease causing.
  • Their consumers, hypertrophy's, unicellular and are classified by movement.
Plant-like Protists:
  • They produce oxygen, autotroph, and they are the first on the food chain.
  • They are multicellular (algae) and some are unicellular-phytoplankton.
  • They produce 1/2 of the worlds oxygen.
Fungi-like Protists:
  • fungus-like slime molds (reproduce via spores) and water molds and downy mildew (flagellated cells)
  • Their decomposers

*LOCOMOTION*
  • The way protists move is sarcodines (pseudopod) which are false feet. Flagellates ( whip-like structures) Ciliates which is hair-like paramecium, and sporozoans which don't move on their own. They need help from water or other stuff.


*Reproduction*

  • They reproduce with their mating tubes.
  • Again, highly variable
  • Asexual by Fission
  • Mitosis, offspring identical
  • strepto- long chains
*Benefits*
* Some of the benefits of the protists are they clean the water by eating and breaking down the toxic waste and other bacterias that can be very harmful. * They are in your lungs and they help break down the mucus and stuff in there.

*Problems*
Some organisms can be harmful because our bodies aren't used to them. There is bacteria based organisms that carry diseases and other harmful bacteria. Also without some types of protists and organisms, the world and Eco-system cant function properly. The protists break-down certain things in water that is harmful to us and makes it better.
