Draw and label the structure of a chloroplast, identifying the site of photosynthesis.

To draw and label its structure:

1. Draw an oval shape to represent the chloroplast.
2. Draw a second oval inside the first, following its contour, to show the inner and outer membranes.
3. Inside the inner membrane, the fluid-filled space is the stroma.
4. Draw several stacks of flattened disc-like sacs. Each stack is a granum (plural: grana).
5. Each individual disc within a granum is a thylakoid.
6. Draw connecting membranes between the grana. These are called stroma lamellae (or intergranal thylakoids).

Labels:

• Outer membrane
• Inner membrane
• Stroma
• Granum (a stack of thylakoids)
• Thylakoid (an individual disc within a granum)
• Stroma lamella (or intergranal thylakoid)
