There are more than 285,000 different species of plants. Plants unlike other living things make their own food. All seed plants have roots, a stem, and leaves. Roots Roots anchor the plant into the ground. Without the root the plant would blow away.
Roots help feed the plant by sucking up water and minerals from the soil.
Stems Stems support the leaves and connect other parts of the plant to the root. Food, water and minerals move through the stem. There are two types of plant stems, herbaceous and woody. Herbaceous stems are soft, green and flexible. Most stems grow above the ground but some, called rhizomes, grow underground.
