4. Types of Leaves

5. Parts of a Leaf Tip: terminal point of a leaf
Blade: flattened green expanded portion
Margin: edge of a leaf
Midrib: most prominent central vein
Lateral veins- secondary veins in a leaf
Petiole- leaf stalk that connects blade to stem
Stipules-leaf-like appendages. They can protect the young leaf and may be modified into spines or tendrils

6. Compound Leaves Leaflet- 20 leaf of a compound leaf
Rachis- an extension of the petiole bearing leaflets
Petiolule- leaflet stalk
Petiole- leaf stalk
Lateral veins- 20 veins in a leaf
Stipules-leaf like appendages

7. Compound Leaves Palmately Compound (digitate)- no rachis
Pinnately Compound (pinnate)- rachis

18. Project due Thursday 8/22! YOU GUYS DID GREAT! Label neatly
10 characteristics could use less than 10 specimens!
Start tonight with your leaves 
YOU GUYS DID GREAT!
