In the plant, 50 or more thylakoids piled upon each other to form:
Correct answer: A. Granum
- A. Granum
- B. Centrosome
- C. Stroma
- D. Multinucleate
Explanation
Granum is the correct answer because it specifically refers to the stacks of thylakoids that are essential in the process of photosynthesis within plant cells. Thylakoids are membrane-bound structures where the light-dependent reactions occur. Other options are incorrect: the centrosome is involved in microtubule organization, the stroma is the fluid medium surrounding thylakoids but not formed by them, and multinucleate describes a type of cell, not a structure related to thylakoids.
