Solution
The correct option is A Mitochondria
The correct option is A:
Explanation of the correct option:
- Cytoplasmic male sterility is the phenomenon that leads to male sterility.
- Specific nuclear and mitochondrial interactions are associated with male sterility in plants.
- These genes responsible for male sterility are present in the mitochondria.
Explanation of the incorrect options:
Option B:
The cytoplasm contains the organelles such as mitochondria, but it does not contain genes responsible for male sterility.
Option C:
The nucleus contains nuclear material and genetic material.
Option D
The genome of chloroplast helps in different processes such as photosynthesis.
Final answer: The progenies are male sterile after crossing two plants. This is due to some genes which are present in mitochondria.
