Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In a plant cell, DNA may be found
A
only in the nucleus
B
nucleus and mitochondria
C
nucleus and choloroplast
D
nucleus, mitochondria, chloroplasts
Explanation: 

Detailed explanation-1: -In plant cells, most DNA is located in the nucleus, although chloroplasts and mitochondria also contain part of the genetic material.

Detailed explanation-2: -Chloroplasts (members of the plastid family) and mitochondria are central to the energy cycles of ecosystems and the biosphere. They both contain DNA, organized into nucleoids, coding for critical genes for photosynthetic and respiratory energy production.

Detailed explanation-3: -DNA is found in mitochondria, plastid & nucleolus. Eukaryotic organisms like animals, plants, fungi, and protists store most of their DNA inside the cell nucleus and some of their DNA in organelles, such as mitochondria or chloroplasts.

Detailed explanation-4: -Summary. Like all living organisms, plants use deoxyribonucleic acid (DNA) as their genetic material. The DNA in plant cells is found in the nucleus, the mitochondria and the chloroplasts.

Detailed explanation-5: -It is found that a single stranded circular DNA is present in the chloroplast which synthesis all the proteins required for photosynthesis. DNA, in plant cells is found within the nucleus, the mitochondria, the chromosome and thus the chloroplasts.
