Reading passage

A plant changes as it grows. All of these changes make a plant’s life cycle. A plant goes through many stages in its life cycle.

A plant begins life as a seed. Flowers make fruit that hold seeds. A seed ahs a baby plant inside. Seeds have special seed coats to protect them. A seed can also come from a cone. The seed sprouts and becomes a seedling. A seedling is a young plant. As it grows up, it becomes taller and thicker. The seedling grows into an adult plant. When the plant grows up, new seeds will begin the new life cycle.
