Anatomy

• The protista can be broken down into four
  catergories on how they move.
• - Zooflagellates move by flagellum.
• - Sarcodines move by the extension of cytoplasm.
• - Ciliates move by cilia.
• - Sporozoans which dont move.
• Protists are mostly unicellular organisms, but
  some are multicellular.
• All are eukaryotic. (have a true nucleus)

(Phytoplankton) ?

Physiology

• Most protists are translucent.
• Come on many different colours depending on the
  species.
• Predominantly unicellular and contains many
  similar organelles.
• These organelles include Nuclei, mitochondria and
  choroplasts.

4
Locomotion

• There are four different ways protists can move.
• - Flagellum This is a tail like structure that
  allows the cell to move by swimming and by the
  extension of the tail.
• Cytoplasm The extension of cytoplasm.
• Ciliates hundreds of small leg like structures.

Obtaining Food

• Since protists are unicellular and full organism
  they obtain the same way any other organism would
  but digest it the way a cell would.
• Amoebas consume by surrounding the prey and
  consume using diffusion.
• Many types of protists however can get energy
  through photosynthesis such as noctiluca.

Diet

• Depending on the phylum a protist is in, they
  consume different things.
• Algal protists and pytoplankton use
  photosynthesis to get their food.

7
Digestion

• Protozoans (Animal like protist) digests food
  through their cytostome, and uses their cytopyge
  to get rid of their waste.
• The way protists digest depends on if they are
  animal like, plants like or even fungi like.

8
Exertion

• Depending on the category the protist fits under
  (animal like, plant like or fungi like) it gets
  rid of their waste through their endoplasmic
  rectilium or cytopyge.

9
Respiration

• In general most protists require oxygen to
  perform respiration.
• Two types of protists however can do respiration
  without oxygen. Some parasitic protists and
  bottom dwelling ciliates.

10
Circulation

• Protiens and waste are circulated throughout the
  protist through the cytoplasm by using
  endocytosis.
• Diffusion is responsible for circulation.

11
Life Cycle

• Amoebas- an amoebas life cycle begins when an
  old existing amoeba subdivides and creates new
  amoeba that looks identical to the pre existing
  amoeba except smaller. The amoeba then subdivides
  and creates more amoebas.
