Understanding photosynthesis processes in green roof plants is crucial to the green roof designer and we have discussed the difference between C3, C4 and CAM photosynthesis processes in prior notes, including;
|Under Intense Sunlight Leaves Fold to Prevent Desiccation|
|Under optimal Sunlight C3 Leaves Open Widely|
|Under Optimal Sunlight Conditions C3 Leaves Open Widely|
Diaheliotropoism describes a plant whose leaves actually track the sun'd path, maximizing solar contact.
Paraheliotroposim denotes a plants actions similar to the above photographs. During parahelioproposim, plants may fold or move their leaves to either;
- Minimize solar contact, or
- Minimize total leaf surface area,
