Study Notes
Plant Structure and Function
- A seed is necessary for a plant to grow, survive, and reproduce.
- Roots grow underground from a seed, holding the plant in place and absorbing water and nutrients from the soil.
- Roots store food (nutrients) for the plant to use later.
Stem
- A stem provides support for the plant, similar to the human spine.
- Stems transport water and food from the roots to the rest of the plant, comparable to veins moving blood through the body.
Leaves
- Leaves grow from the stem and make food for the plant through photosynthesis.
- Photosynthesis involves taking in sunlight, carbon dioxide, and water, and producing oxygen and glucose.
- Evergreen plants, like pine trees, make food all year long.
- Leaves are essential for producing oxygen, which all living things need.
Flowers and Fruits
- Flowers produce pollen, a powdery substance that helps plants make seeds.
- Pollination occurs when animals, like bees, transfer pollen between flowers, allowing the plants to fertilize and reproduce.
- Some plants rely on insects and birds for pollination, and grow colorful flowers to attract them.
- Some flowers, like those on the blueberry bush, develop into fruits that protect the seeds of the plant.
