Storage organs ?

Storage organs are specialized structures in plants that store nutrients, water, and energy for future use. These organs can include roots, tubers, bulbs, corms, and rhizomes. These storage organs allow plants to survive periods of drought or other unfavorable conditions by providing a reserve of essential resources.

Roots:

- Taproot: Elongated, primary root extending deep into the soil
- Fibrous root: Many fine, branching roots spread out near the soil surface
- Tuberous root: Enlarged, fleshy root that stores starch, e.g., potato
- Cormoid root: Flask-shaped root, e.g., turmeric

Stems:

- Rhizome: Horizontal, underground stem with nodes and internodes
- Tuber: Swollen, underground stem, e.g., potato
- Bulb: Short, vertical stem with fleshy scales, e.g., onion
- Corm: Swollen, fleshy stem with a solid center, e.g., gladiolus

Leaves:

- Succulent leaves: Thick, fleshy leaves that store water, e.g., succulents
- Cotyledons: First leaves of a plant, often with stored nutrients
- Scales: Modified leaves that form protective covers, as in bulbs and rhizomes

Other Specialized Structures:

- Modified roots:
- Nodules: Swellings on roots that fix nitrogen
- Aerial roots: Roots that grow above ground for support or absorption
- Modified leaves:
- Tendrils: Slender, coiling structures for support
- Thorns: Spines for protection
- Spines: Leafless structures adapted for photosynthesis
- Special cells:
- Parenchyma cells: Store starch, sugar, and other nutrients
- Tracheary vessels: Transport water and minerals
- Turgid cells: Store water and maintain plant structure
