| Front | What is the function of the chloroplast |
|---|---|
| Back | Chloroplast envelope- double plasma membrane, highly selective of which materials can enter the chloroplast Grana- stacks of up to 100 discs like structure called thylakoids. Inside thylakoids are pigments called chlorophyll. Some thylakoids join up. Grana is where the first stage of photosynthesis occurs (light absorption). They have a large surface area for chlorophyll, electron carries and enzymes. Stroma- fluid filled matrix where second stage of photosynthesis occurs (synthesis of sugars). Fluid of stroma contains all the enzymes needed to carry out the second stage of photosynthesis Chloroplast contain DNA and ribosomes so they can quickly manufacture Proteins required for photosynthesis. Intergranal lamella joins grana together |
