Endosymbioses that lead to the evolution of euglenoids and, separately, the evolution of chlorarachniophytes were the result of the combining of:
a. two ancestral nonphotosynthetic prokaryotes.
b. two ancestral photosynthetic prokaryotes.
c. a nonphotosynthetic eukaryote with a photosyntheticeukaryote.
d. a photosynthetic prokaryote with a nonphotosyntheticeukaryote.
e. mitochondria with an already established plastid.

Describe the Theory of Endosymbiosis. a) Briefly define the Endosymbiotic Theory. 2 pts,b) Explain why the Theory of Endosymbiosis is considered a “theory” and not a “hypothesis.” 3 pts,c) Provide a description of eukaryotic and prokaryotic cells, including at least 4 similarities and 4 structural differences. 4 pts,d) Describe the sequence of events with anaerobic ancestral proto-eukaryotes and aerobic prokaryotes that led to the formation of mitochondria and chloroplasts inside eukaryotic cells. (Be sure to define aerobic and anaerobic respiration.) 6 pts,e) Explain how each, the anaerobic ancestral proto-eukaryotes and aerobic prokaryotes, benefited from the relationship. 4 pts,f) Describe 7 pieces of evidence for this scientific theory. Some of this evidence will consist of a list of similarities between mitochondria characteristics and bacteria characteristics. Along with this list of similarities, explain HOW the characteristics are similar. 10 pts,g) The Endosymbiotic Theory…
What do the multiple branching points at the root of the eukaryotic phylogenetic tree indicate about the evolution of eukaryotes?
A. that unikonts are derived from the SAR clade
B. that Archaeplastids were the first eukaryotes
C. that fungi are more closely related to plants than animals
D. that eukaryotes are all descended from a common ancestor
How did the evolution of oxygen-releasing photosynthesis in cyanobacteria increase the likelihood that mitochondria would one day evolve?

These parasites typically live in low-oxygen conditions and therefore loss of genes for plastids and mitochondria did not result in lower fitness B.
