Essential Needs for Plant Growth

The video explains how plants grow, focusing on the core four essentials: soil, sunlight, air, and water. It details how each element contributes to plant health and growth, including the role of nutrients in soil, the process of photosynthesis, and the importance of water balance. Additional factors like temperature and space are also discussed. The video concludes with a review of these concepts, emphasizing the interconnectedness of life on Earth.
