Study Notes
Leaf Classification Basics
- Leaves can be classified based on venation and structure (simple vs compound).
- Dicot leaves typically exhibit netted venation patterns like pinnate and palmate.
- Monocot leaves primarily show parallel venation.
Types of Venation
- Dicot Venation:
- Palmate: Veins spread out from a central point resembling a hand.
- Pinnate: Veins branch off from a single midrib.
- Monocot Venation:
- Parallel: Veins run parallel to the midrib, common in long and narrow leaves.
Leaf Composition
- Veins consist of xylem and phloem:
- Xylem: Transports water.
- Phloem: Carries food, primarily in sugar form.
Leaf Structure Features
- Petiole: Short stem connecting the leaf blade to the stem.
- Leaflet: A smaller section of a compound leaf lacks its own petiole.
- Simple Leaf: A single, undivided leaf without leaflets.
- Compound Leaf: Composed of multiple leaflets, situated at the main stem.
Bud Structures
- Axillary Bud: Found in the angle between the stem and petiole; helps promote fullness.
- Terminal Bud: Located at the end of a stem; assists in vertical growth.
Stem Terminology
- Node: The point on a stem where a leaf emerges.
- Internode: The space between two nodes.
Leaf Arrangement
- Leaves can be arranged as simple or compound:
- Whorled Arrangement: Multiple leaves at a single node (specific to dicots).
Additional Classification Notes
- Dicot leaves can be characterized as simple or compound with varied venation.
- Arrangements vary, as well as the role of axillary buds depending on leaf type.
Key Takeaways
- Differentiating leaves involves understanding their venation, structure, and bud arrangements.
- Learning the specific characteristics of dicot and monocot leaves aids in proper classification.
