a.Organelles that arose by endosymbiosis
b.Organelles that arose by secondary endosymbiosis
c.Mitochondria
d.Plasmids
e.Flagella
2.Which of the following statements supports the hypothesis of an endosymbiotic origin of mitochondria? Select all correct answers.
a.Some algae contain plastids surrounded by four membranes.
b.Each mitochondrion has a single, circular DNA molecule.
c.Diplomonads have modified mitochondria called mitosomes.
d.Mitochondria contain prokaryotic-type ribosomes.
Homework Answers
1. Prokaryotes are not monophyletic. They can be polyphletic becuase it includes both archea and bacteria . And can also be paraphyletic as it descended from a common evolutionary ancestor or ancestral group that is prokaryotic lineages but not including all the descendant groups.
2. Prokaryotes include chemoautotrophs , photoautotrophs , chemoheterotrophs and photohetrotrophs.
1. Statement a and c is correct .
2. Statement c is correct as diplomonads do have modified mitochondria which is known mitisomes in them . Mitochondria do not contain prokaryotic type ribosome .
