Study Notes
Leaf Anatomy
- A typical leaf consists of three main parts: blade, petiole, and stipules
- The petiole is the stalk that attaches the leaf to the stem, allowing for flexibility and movement
Leaf Venation
- Most monocotyledons have parallel venation, where veins run parallel to each other
Leaf Bases
- In some leguminous plants, the swollen leaf base is called a pulvinus
Leaf Support and Transport
- The vascular tissues (xylem and phloem) provide rigidity to the leaf blade and act as channels for the transport of water, minerals, and food materials
