Explanation:
I just took the quiz. That was the correct answer.
chloroplasts reproduce by binary fission. The endosymbiotic theory describes how mitochondria and chloroplasts descended from the same type of bacteria. According to the theory, a host cell ingested symbiotic bacteria, which specialized into chloroplasts. The evidence for this is that chloroplasts reproduce by binary fission similarly to bacteria.
Hi!
The two types of endoplasmic reticulum are:
Rough Endoplasmic Reticulum RER
Smooth Endoplasmic Reticulum SER
The major difference between the two is the presence of ribosomes. The membrane of rough endoplasmic reticulum is bound by ribosomes, whereas the smooth endoplasmic reticulum is not bound by ribosomes.
Another difference lies in their function. RER is a storage house for proteins and is where the proteins are manufactured whereas SER is known for storing lipids and proteins both.
