These are the current major groups of protists:

• Excavata

• Chromalveolata

• Rhizaria (Rhodophyta)

• Archaeplastida

• Amoebozoa and Choanozoa

How do protists move?

• by means of standard organelles

• carried by wind, water, or other organisms

• All the above

• by cilia and flagella

How do protists reproduce?

• By mitosis

• sexually

• sexually

• By meiosis

• All the above

Protists with life cycles that switch between a diploid (sexual) and haploid (asexual) phase through their life cycle describes:

• Alternation of generations

• Alternation of populations

• Differentiation of generations

• Growth of generations

Protists that perform photosynthesis?

• Autotrophic protists

• Mutualist protists

• Parasitic protists

• Plant protists

Protists that are involved in mutualistic relationships with other organisms- both benefit Ex. lichens

• Autotrophic protists

• Mutualist protists

• Parasitic protists

• Plant protists
