Function of Each Part in a Chloroplast
Asked by Rukhsar Ahmedullah · 2 years ago
What are the functions of the different parts of a chloroplast as per the NCERT syllabus?
1 Answer
Great question! Each part of a chloroplast has a specific function vital for photosynthesis:
1. **Outer Membrane**: Acts as a protective barrier for the chloroplast.
2. **Inner Membrane**: Regulates the passage of materials in and out of the chloroplast.
3. **Stroma**: Contains enzymes necessary for the light-independent reactions (Calvin cycle) of photosynthesis. It also houses chloroplast DNA and ribosomes.
4. **Thylakoid**: Contains chlorophyll and other pigments that capture light energy. It is the site of the light-dependent reactions.
5. **Granum (plural: Grana)**: Increases the surface area for light-dependent reactions to occur.
6. **Thylakoid Lumen**: Plays a role in the formation of a proton gradient, which is essential for ATP synthesis.
7. **Lamellae**: Connects different grana, facilitating the transfer of energy and materials between them.
Each of these parts works together to ensure the chloroplast functions efficiently in the process of photosynthesis.
