lamella
Quick Summary
The lamella refers to the internal membranes within a chloroplast, the organelle responsible for photosynthesis in plants and algae. These membranes are composed of roughly equal parts lipids and proteins. Within the lamellae are chlorophyll pigments, which absorb light energy from the sun. This absorbed energy is crucial for converting light energy into chemical energy, a process that fuels the plant's growth. The lamellae are organized into flattened sacs called thylakoids, which can stack to form grana. These structures are essential for the light-dependent reactions of photosynthesis.12345
