1. Roots:
* Function: Anchor the plant in the soil, absorb water and minerals from the soil, store food.
* Types: Taproots (single, large root), Fibrous roots (numerous, smaller roots), Adventitious roots (roots that grow from stems or leaves).
2. Stems:
* Function: Support the leaves and flowers, transport water and nutrients between the roots and leaves, store food.
* Types: Herbaceous stems (soft, green), Woody stems (hard, brown), Underground stems (e.g., rhizomes, bulbs).
3. Leaves:
* Function: Photosynthesis (convert sunlight into energy), transpiration (release water vapor), gas exchange (take in carbon dioxide and release oxygen).
* Types: Simple leaves (single blade), Compound leaves (multiple leaflets).
4. Flowers:
* Function: Sexual reproduction, producing seeds.
* Parts: Sepals (protect the flower bud), Petals (attract pollinators), Stamens (produce pollen), Pistil (female reproductive organ).
5. Fruits:
* Function: Protect and disperse seeds.
* Types: Simple fruits (develop from a single ovary), Aggregate fruits (develop from multiple ovaries on a single flower), Multiple fruits (develop from multiple flowers).
6. Seeds:
* Function: Contain the embryo of the plant, allow for reproduction and dispersal.
* Parts: Seed coat (protects the embryo), Endosperm (nutritive tissue), Embryo (contains the radicle, plumule, and cotyledons).
Note: While these are the major organs, plants also have specialized tissues within these organs, such as vascular tissue (xylem and phloem) for transport, and parenchyma tissue for storage and photosynthesis.
