Study Notes
Leaf Composition
- A simple leaf has a continuous undivided surface.
- A lobed leaf has incisions that do not reach the midrib.
- A compound leaf has incisions that reach the midrib.
Leaf Lamina
- The lamina is the blade of the leaf.
- The size of the lamina is measured by its length and width.
- The margin of the lamina can be:
- Entire (smooth)
- Serrate (toothed)
- Crenate (rounded teeth)
- Dentate (sharp teeth)
- Sinuate (wavy)
- Ciliate (hairy)
Leaf Venation
- There are two main types of venation: parallel and reticulate.
- Parallel venation: veins are parallel to the midrib.
- Reticulate venation: veins are interconnected and form a network.
- Types of reticulate venation:
- Pinnate reticulate: veins radiate from a central midrib.
- Palmate reticulate: veins radiate from a central point.
- Anastomosing venation: veins are interconnected and form a network.
Leaf Taste
- Leaves can have different tastes:
- Bitter
- Mucilaginous
- Salty
- Characteristic (unique to the plant)
