Study Notes
Silajila (Teridophyte)
- Introduction to Silajila, a type of Teridophyte
- Silajila is a long topic, to be covered in multiple parts
Habitat and Distribution
- Found in tropical countries, including India (around 70 species)
- Grows in shaded regions with high humidity and low light
- Found in tropical rainforests, temperate regions, and tropical mountains
External Morphology
- Silajila has an evergreen, delicate habit
- Its size varies greatly, from a few cm to 20 meters
- Stem is monopodial, meaning it grows from a single apex
- Leaves are small, simple, and arranged spirally on the stem
- Stem is erect, but can also be prostrate (lying down)
Stem Structure
- Stem is divided into two parts: homoiodic and heterotopic
- Homoiodic: similar in structure
- Heterotopic: different in structure
- Epidermal cells are present on the surface of the stem
- Meristematic tissue is present in the growing region of the stem
Leaf Structure
- Leaves are small, simple, and lack a true petiole
- They have a pointed apex and are arranged spirally on the stem
- Leaves are of two types: small and large
- Small leaves are present on the dorsal side of the stem
- Large leaves are present on the ventral side of the stem
Rhizomes
- Rhizomes are underground stems that produce new plants
- They are root-like structures that grow horizontally
- Rhizomes produce new shoots and roots at their tips
Roots
- Roots are absent in Silajila
- Instead, it has rhizoids that anchor the plant
- Rhizoids are small, root-like structures that absorb water and nutrients
Importance
- Silajila has medicinal properties
- It is used in traditional medicine to treat various ailments
