The Stolen Sun: Chloroplast Origin Explained

Around 1.5 billion years ago, one cell engulfed another and instead of digestion, a permanent biological partnership was born. Chloroplast origin explained through the endosymbiotic theory is one of the most evidence-backed...

Questions: 20 | Attempts: 11 | Last updated: Mar 2, 2026

Sample Question 1
What does the endosymbiotic theory suggest regarding the chloroplast origin?

They were made by the Golgi

They evolved from the nucleus

They originated as free-living photosynthetic bacteria

They formed from folded cell membranes

They were delivered by a virus

Sample Question 2
Chloroplasts were originally free-living cyanobacteria before being engulfed by a host cell.

True

False

Sample Question 3
Which piece of evidence regarding DNA supports the theory of the chloroplast origin?

Chloroplasts have no DNA

Chloroplast DNA is linear like human DNA

Chloroplasts have circular DNA similar to bacteria

Chloroplast DNA is stored in the nucleus

Chloroplast DNA is made of RNA
