Overview
This lecture covers the six main parts of plants and their functions, focusing on how each part helps the plant grow and reproduce.
Plant Parts Overview
- Plants have six main parts: roots, stems, leaves, flowers, fruit, and seeds.
- The first three (roots, stems, leaves) help plants get water, make food, and grow.
- The last three (flowers, fruit, seeds) help plants reproduce and grow new plants.
Roots
- Roots anchor the plant in the soil and absorb water and nutrients.
- Roots are typically underground but can sometimes be above ground.
Stems
- Stems hold the plant upright above ground.
- Stems transport water and nutrients from roots to other parts of the plant.
Leaves
- Leaves grow at the ends of stems.
- Leaves use air, sunlight, and water to make food for the plant through a process called photosynthesis.
Flowers
- Flowers grow at the ends of stems and are often colorful to attract pollinators.
- Flowers become pollinated and then make seeds and fruit.
Fruit
- Fruit grows on the ends of stems and contains seeds.
- Fruit can be eaten or fall and rot; both ways help spread seeds.
Seeds
- Seeds are found inside fruit.
- Seeds can grow into new plants after dispersal, either by animals or by falling to the ground.
Key Terms & Definitions
- Roots — Hold the plant in the soil and absorb water/nutrients.
- Stems — Support the plant and transport water and nutrients.
- Leaves — Make food for the plant using sunlight, air, and water.
- Flowers — Colorful parts that attract pollinators and produce seeds and fruit.
- Fruit — Holds and protects seeds until they are spread.
- Seeds — Can grow into new plants when conditions are right.
Action Items / Next Steps
- Review the names and functions of all six plant parts.
- Practice identifying each part in plant diagrams or real plants.
