Chloroplast Anatomy
- Outer membrane: Serves as a protective barrier, maintaining the structure of the chloroplast.
- Stroma: The colorless, fluid matrix surrounding the thylakoids, integral for the Calvin cycle and the synthesis of organic molecules.
- Thylakoid: Membrane-bound sacs located within the chloroplast, crucial for the light-dependent reactions of photosynthesis, capturing light energy.
- Granum: A collection of thylakoids stacked together, enhancing the efficiency of light absorption and photosynthetic processes.
- Lamellae: Membrane structures that link multiple granum together, facilitating the transport of molecules between them.
- Inner membrane: Contains proteins involved in the electron transport chain, playing a critical role in energy transformation during photosynthesis.
