Class XI Practical: Morphology - Study of Phyllotaxy, Leaf Types, Venation, etc.

Objective

To observe and identify different patterns of phyllotaxy, types of leaves (simple/compound), and venation patterns in various plant specimens.

Specimen Collection: Collect diverse plant specimens showing different arrangements of leaves, leaf types, and venation patterns.
Phyllotaxy: Observe the arrangement of leaves on the stem and identify:
- Alternate: (e.g., China rose, mustard)
- Opposite: (e.g., Guava, Calotropis)
- Whorled: (e.g., Alstonia)
Leaf Types: Examine leaves and distinguish between:
- Simple Leaf: (e.g., Mango, Guava)
- Compound Leaf: (e.g., Neem, Rose) - further classify as pinnately or palmately compound.
Venation: Observe the arrangement of veins and veinlets in the leaf lamina and identify:
- Reticulate Venation: (e.g., Dicot leaves like peepal, mango)
- Parallel Venation: (e.g., Monocot leaves like grass, banana)

Ability to accurately identify and classify phyllotaxy patterns, leaf types, and venation patterns in different plants.
