Topic 1 Taxonomy: Eukaryotes

Question 1

• Kingdom of (mostly unicellular) eukaryotic organisms

Answer 1

Protists

Question 2

• No cell wall made of chitin
• Can move via cilia or flagella
• Saprophytic
• Feed via phagocytosis
• Reproduce via asexual reproduction and sporulation

Answer 2

Fungus-like protists

Question 3

• One of the most important primary producers
• Algae encompasses a large variety of plant-like protists due to having chloroplasts and photosynthetic ability
  a. Diatoms and euglenoids are unicellular, photosynthetic autotrophs that reproduce asexually and are found in aquatic environments
  b. Dinoflagellates: responsible for red tide (toxins build up, O2 in water is depleted), have two flagella (find food in absence of light), and are heterotrophic (parasitic)

Answer 3

Plant-like (algae-like) protists

Question 4

• Known as protozoa
• Have food vacuoles
• Include amoeba and paramecium
• Heterotrophic (move via flagella and cilia)
• Often parasitic pathogens

Answer 4

Animal-like protists
