Study Notes
Plant Morphology
Vegetative Reproduction
- Runners of Oxalis and grasses help in vegetative reproduction
- Stem tendrils help in climbing in pea
Modifications of Leaves
- Insectivorous plants grow in nitrogen deficient soil and capture insects
- In Utricularia, leaf segments are modified into small sac or bladder for catching small insects
- In Dionaea, the whole of the leaf is modified into a pitcher
- In Australian Acacia, petioles and rachis are vertical, flat, and photosynthetic
- In Asparagus, leaves become modified into spines
Flowers
- Stamens show variation in the length of filament within a flower
- Silky threads of maize represent styles
- A flower that cannot be divided into two similar halves by any vertical plane passing through the center is found in Cassia
Stem
- Cuim formation occurs in Palm trees
- Annuals and biennials are typically monocarpic
- Apocarpous condition of Gynoecium is seen in three plants: Ranunculus, Petunia, and Lotus
Roots
- Syngenesious condition refers to the cohesion of stamens
- Hypogynous flowers have flowers attached to the thalamus
- Epigynous flowers have flowers arising from the ovary
- Perigynous flowers have flowers attached to the calyx
Phyllotaxy
- Alternate phylaxy is seen in China rose

Stem Tendrils
- Stem tendrils are modified stems that help in climbing
- Thorns are modified stems
- Cladode is a modified root
Roots
