Chloroplast

ACTSCI-HFYKM6

A cell biologist tells you about a structure called a chloroplast and explains to you that this cell part is found only in plant cells. She tells you that the chloroplast helps the plant produce energy and that it contains its own genetic material and may make copies of itself. After studying this new information, you are asked which theory of cell evolution the example of the chloroplast supports.

Which statement would be correct based on the evidence presented?

Inside Out or Outside In

A

The chloroplast supports the “outside-in” theory because it is a bleb and can swallow large eukaryotic cells.

B

The chloroplast supports the “outside-in” theory because it is a prokaryotic cell capable of swallowing eukaryotic cells.

C

The chloroplast supports the endosymbiotic theory because it is a prokaryotic cell capable of swallowing mitochondria.

D

The chloroplast supports the endosymbiotic theory, as like the mitochondria, it could have been a small cell that survived on its own before being taken in.
