Unit 1. Plants

Plants have leaves, roots, stems, and flowers. They produce seeds and make their own food through photosynthesis. The main parts of a plant are the roots, which take in water; the stem, which supports the plant; the leaves, which take in sunlight and air; and the flowers, which produce seeds. Seeds grow inside fruit, which protects the seeds, and then animals eat and disperse the seeds so new plants can grow. There are different types of plants like trees, bushes, and grass. Trees have thick trunks and roots and can be deciduous, losing leaves in autumn, or evergreen, keeping leaves all year. Plants need water, light, air, and soil to grow and reproduce
