Question

Mitochondrial and Chloroplasts are similar because
A. Both have Nuclei
B. Both have 80S Ribosomes
C. Both have DNA
D. Both have single membrane envelope

Answer 1

Hint: Mitochondrial and chloroplast are two organelles that are found in the plant cells. Among them only mitochondria can be found in the animal cells. The main function of both of them is to produce energy for the cell they live in. They are the main source of energy of a cell.

Complete explanation
Option A. Both have Nuclei: Mitochondria doesn’t contain a Nucleus. But the chloroplasts are mostly controlled by the nucleus. The plural form of nucleus is nuclei.
So, Option A. Both have Nuclei is not the right answer.
Option B. Both have S Ribosomes: We can find Ribosomes in Eukaryotic cells like Mitochondria and Chloroplasts. They both have S Ribosomes just like the Prokaryotic cells. But except from these two organelles other eukaryotic cells have S ribosomes.
So, Option B. Both have 80S Ribosomes is not the correct answer.
Option C. DNA: They both have DNA to produce energy.
SO, Option C. DNA is the correct answer.
Option D. Both have single membrane envelopes: Mitochondria and chloroplast both have double membrane envelopes.
So, Option D. Both having a single membrane envelope is not the correct answer.

Hence, Option C. DNA is the correct answer.

Note:
Both mitochondria and chloroplasts can produce energy for the cells they are living in as they have S ribosomes and DNA. We can find the DNA of a chloroplast in the nucleus. But as there is no nucleus in a mitochondria, the DNA is free in the cell cytoplasm. Mitochondria is called the “Kitchen of a Cell” as it produces the required energy for the cell.
