Diatoms contain chloroplasts that have four membranes. These four membranes are evidence of secondary endosymbiosis (Option c).
<h3>What is secondary endosymbiosis?</h3>
Secondary endosymbiosis is a hypothesis used to explain why diatom chloroplasts have four membranes.
According to this hypothesis, diatoms received different genes from distinct photosynthetic and non-photosynthetic ancestors.
The acquisition of genes of different ancestors led to diatoms having chloroplasts with four membranes.

What controls what molecules pass in and out of a cell?
An easy way to tell is if the trait is or isn’t in every generation. If a trait skips a generation, it’s most likely recessive.
DNA and RNA both produce proteins, but RNA copies itself and moves out of the nucleus while DNA stays inside the nucleus and produces proteins. Also DNA helps more in cell division, while RNA helps in making proteins.
