What are Plants • Plants are living things that do not move. • Many plants are green. • Plants usually make their own food. • Plants produce other plants like themselves. • Plants are used by humans for food, shelter, and drugs.
What a Plant Needs • Water • Air • Light • Soil
Seeds • Most plants begins with seeds. • We can eat the seeds of some plants, such as sunflowers. • When a seed gets water and warmth, it germinate, or start to grow. • Parts of a seed: • Embryo • Seed coat • Stored food
Roots • Most roots grow down into the soil. • Roots absorb water and minerals from the soil. • Roots take nutrients for the plant. • Roots also hold the plant in place. • Carrots, beets, and potatoes are roots we eat.
Stems • Stems grow up from the roots to hold up the plant. • Stems carry food and water to the rest of the plant. • Most stems are soft, but a tree has a hard stem called a trunk. • Celery is a stem we eat.
Leaves • The leaves of the plant are full of chlorophyll. • Chlorophyll makes the plant green. • Chlorophyll uses soil, sunlight, and air to make food for the plant. • A plant can make its own food (photosynthesis).
Flowers • Flowers are important in making seeds and fruits through the process of fertilization. • Flowers have some basic parts: female and male parts. • Petals attracts bees and butterflies.
