Study Notes
Plastids
- There are two main types of plastids: chloroplasts and leucoplasts.
- Chloroplasts are responsible for the process of photosynthesis, converting light energy into chemical energy.
- Leucoplasts are responsible for the storage of starch.
- Plastids and mitochondria share a unique feature: they have their own DNA and ribosomes, suggesting an independent evolutionary origin.
Chloroplast Organization
- The internal organization of chloroplasts is primarily composed of a system of interconnected membranes called thylakoids.
- These thylakoids are stacked into grana, which are interlinked by stromal lamellae.
- The space enclosed by the thylakoid membrane is the thylakoid lumen, while the space between the thylakoid membrane and the inner membrane is the stroma.
