- Colo. Master Gardeners Leaves
- Concept Map for leaves
- Interactive Transpiration tutorial.
- What is the primary function of the leaf?
- What is photosynthesis?
- From where does the leaf get its water (H2O)?
- From where does the leaf get its carbon dioxide (CO2)?
- What does the plant use the sugars made by photosynthesis for?
- Where does the oxygen (O2) made by photosynthesis go?
- How does carbon dioxide (CO2) get into the leaf and oxygen (O2) get out of the leaf?
- Explain two functions of transpiration.
- Where does transpiration water come from and where does it go?
- Why do plants have to be able to close the leaf stomata?
Each drawing is evaluated using a Visual Presentations Rubric

- Internal leaf structure: Sketch and label a leaf cross section . Labels: stomata, epidermal cells, palisade cells, spongy mesophyll, chloroplasts, vein.
- Leaf Attachment Drawing: Sketch the following pattern of leaf attachments: alternate, opposite, whorled.to describe the leaf shape.
