Question
Choose the odd one out
- Thylakoid
- Stroma
- Grana
- Lamina
The correct answer is: Stroma
- Stroma is a homogeneous membrane which contains grana
- It is similar to cytoplasm of the cell in which organelles are embedded
- Thylakoid is a membrane bound compartment inside chlorophyll and cyanobacteria
- Thylakoids are the site of light reactions of photosynthesis
- Thylakoids have lumen .
- Thylakoids are arranged in stacks called as grana
- The two grana are interconnected by lamellae
- Hence odd one out is the stroma in which these structures are embedded
