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.
