Textbook Question
Chapter 27, Problem 3TYK
Some prokaryotes have specialized internal membranes that
- a. have attached ribosomes and function in protein synthesis.
- b. arose from endosymbiosis of smaller prokaryotes, evolving into mitochondria and chloroplasts.
- c. form from infoldings of the plasma membrane and may function in
cellular respiration or photosynthesis. - d. separate plasmids from the single prokaryotic chromosome located in the nucleoid.

Small circular pieces of DNA that are found in the cytoplasm of aprokaryotic cell are calleda. capsules.b. nucleoids.c. plasmids.d. ribosomes.
According to the theory of endosymbiosis, organelles, like mitochondria and chloroplasts, were once free-living cells that were absorbed into another cell. The relationship benefited both cells to stay together. What evidence do scientists observe today that supports the theory of endosymbiosis? Select all that apply.
a
There are ribosomes found inside mitochondria and chloroplasts just like there are inside cells.
b
Looking inside mitochondria and chloroplasts, one will find that they each contain their own DNA.
c
Mitochondria and chloroplasts are found inside all cell types.
d
Mitochondria and chloroplasts each have a membrane around them just like a cell would.
Mitochondria are thought to be the descendants of certain alpha proteobacteria. They are, however, no longer able to lead independent lives because most genes originally present in their genome have moved to the nuclear genome. Which phenomenon accounts for the movement of these genes?
Group of answer choices
A. recombination
B. conjugation
C. translation
D. endosymbiosis
