Protists

• Are protists prokaryotic or eukaryotic?

  Eukaryotic
• What Kingdom do they belong to?

  Protista
• Protists exist as both multicellular and unicellular. They can also be colonial
• Can protists be both autotrophic and heterotrophic?

  Yes
• What are the 3 groups of Protista?

  1. Animal-like (Protozoa)
  2. Fungi-like (Moulds- slime and water moulds)
  3. Plant-like (Algae)
• Are the 3 groups of protista related?

  No
• Animal-like (protozoans) are all heterotrophic and unicellular.

  They can be free-living protozoans, symbionts or parasites
• Fungi-like are heterotrophic, and can be both multicellular or unicellular (at different life stages). They can also reproduce both sexually and asexually. Their cell wall is made up of cellulose (unlike true moulds and fungi). What are the 3 types of slime moulds?

  1. cellular slime moulds
  2. plasmodial slime moulds
  3. water moulds
• Plant-like are autotrophic, can be multicellular or unicellular, and can be colonial or coencytic. Classification based on pigments and cell chemistry.
• Plant-like:

  What are the 2 major groups of unicellular algae?

  1. Dinoflagellates
  2. Diatoms

  What are the 3 major groups of multicellular algae?

  1. Browns
  2. Reds
  3. Greens
• Do all protists have a nucleus? Yes
• Protists are neither plant, animal or fungi. They are sometimes referred to as the 'junk draw' kingdom.
