The Essential Needs For Healthy Plant Growth

This video tutorial explains the basic needs of plants for healthy growth and survival. It covers the importance of air, water, nutrients, sunlight, space, and proper care. Air is essential for photosynthesis and respiration, while water is crucial for photosynthesis and nutrient absorption. Nutrients from the soil help plants grow and resist diseases. Sunlight is necessary for photosynthesis, and adequate space allows roots to spread and absorb nutrients. Proper care, including regular watering, sunlight exposure, and protection from pests, ensures healthy plant development.
