This document discusses the life processes of plants. It explains that plants need sunlight, water, carbon dioxide, and mineral salts to survive. It describes the processes of photosynthesis, where plants make their own food, and respiration. Photosynthesis requires sunlight, water, and carbon dioxide to produce oxygen, food for the plant, and waste products like oxygen and carbon dioxide. The document also covers asexual and sexual reproduction in plants, and the stages of crop farming.
