◉ According to this phylogenetic tree the entirety of protist form a
______ group..
Answer:
◉ Why are "protists" a ________ group ?.
Answer:
◉ what evolved in protists.
Answer: earliest euk single celled organism w/
-mitochondria
-nucleus w endomembrane syst
-cytoskeleton
-no cell wall.
◉ endomembrane system.
Answer: organelles w similar membrane structures; can pass things
among themselves easily
