What is Seondary Endosymbiosis? When a protists is "absorbed" or ingested by another protist. It is a driving force in protist evolution
What organisims are most commonly involved with Secondary Endosymbiosis? Red or green algae
What is a result of Secondary Endosymbiosis? A more complex type of protist which can become a new species
What are the five main groups of protists? (discussed in class) (1) Excavata (2) Chromalveolata (3) Rhizaria (4) Archaeplastida (5) Unikonta
What is Algae? Eukaryotic photoautotrophs that are usually unicellular but some are mulitcellular. "plan-like", plats of the ocean. Can reproduce sexually and asexually
