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. Leaves Leaves produce food for the plant. In the leaves are tiny openings called stomata. There are about 9,000 to 72,000 stomata per square centimeter of surface area. Photosynthesis happens when the sunlight hits the leaves.
