Question

In the higher plants, the stroma in the chloroplasts possesses _________.

• A. light-harvesting complexes (LHC)
• B. light­-dependent reaction enzymes
• C. light-independent reaction enzymes
• D. chlorophyll

Answer 1

The correct option is C light-independent reaction enzymes

In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The thylakoid membrane encloses a space termed lumen, and the jelly-like substance the thylakoid is suspended in is the stroma. The stroma is where the light-independent reactions occur.


Light-harvesting complexes (LHC): The LHC are made up of hundreds of pigment molecules like chlorophyll b (yellow green), xanthophylls (yellow) and carotenoids bound to specific proteins and are embedded in the thylakoid membrane of plants.

Chlorophyll: Chlorophyll is a green pigment located within the thylakoid membrane inside the chloroplasts.
