This document discusses the parts of plants and their life cycles. It explains that plants need sunlight, air, water, and nutrients from soil to grow. The main parts of a plant are the roots, which take in water and nutrients; the stem, which carries water and nutrients; and the leaves, which use sunlight to make food through photosynthesis. Flowers produce fruits containing seeds. Seeds come in many shapes and sizes and can be scattered by the wind, water, animals or planting. When conditions are right, seeds germinate and a seedling grows into a new plant, completing the life cycle.
