This answer is closest to correct.
Chloroplasts;
These contain grana, the site of the light-dependent reaction of photosynthesis, and stroma, a fluid substance that is the equivalent of cytoplasm in cells, which is the site of the light-independent reaction of photosynthesis. Grana are structures made of stacked thylakoid membranes, necessary for chemiosmosis, connected to one another by lamellae.
DNA in the nucleus of eukaryotic cells is collected into a chromatin.
A chromatin is a complex of nucleic acids (DNA or RNA) and proteins called histones which condense to form a chromosome during cell division.
In eukaryotic cells, it is found within the cell nucleus while in prokaryotes, it is found inside the nucleoid .
Its functions are;
1. to package DNA into a smaller volume to fit in the cell.
2. strengthen the DNA to allow mitosis and meiosis.
3. acts as a mechanism to control expression
The chromatin is easily recognized through staining. Its name literally means "colored material."
