The Structure of a Plant
Plants have different parts, and each part has a special role. The Two Main Parts of a Plant:
- Stem: This part of the plant grows above the ground.
- Root: This part grows below the ground.
The roots, stems, and leaves are the most important parts of a plant. From time to time, plants also produce flowers that help in reproduction. These flowers later turn into fruits with seeds that grow into new plants.
The structure of a plant
Plant Parts and Their Functions:
| Plant Part | Structure/Type | Main Functions | Special Features |
|---|---|---|---|
| Flower | Colorful, fragrant, with stalk (long or short) | Helps in reproduction; produces seeds | Attracts pollinators |
| Leaf | Flat; Simple or Compound | Performs photosynthesis; makes food | Uses sunlight, water, and CO₂ |
| Stem | Varies in height and thickness | Supports plant; transports water, nutrients, and food | Stores food in some plants; helps in reproduction |
| Fruit | Various shapes and sizes; contains seeds | Houses seeds; aids in reproduction | Examples: beans, pea pods |
| Root | Grows underground; Taproot or Fibrous | Anchors plant; absorbs and transports water and nutrients | Stores food in some plants like carrots and radish |
