What is a stack of thylakoids inside a chloroplast called?
AA granum
BA lumen
CA stoma
DA stroma
Answer & Solution
Correct answer: A. A granum
1. Thylakoids are stacked disc-shaped structures inside a chloroplast.
2. A stack of thylakoids located inside a chloroplast is called a granum.
3. The liquid-filled space surrounding the granum is the stroma.
4. A stoma is an opening on the leaf epidermis, so the near-identical spelling is the trap here.
