Plant growth is a natural biological process through which plants increase in size, develop new structures, and complete their life cycle. It begins with seed germination, where a seed absorbs water and starts developing roots and shoots. As the plant grows, it forms leaves, stems, flowers, and fruits through continuous cell division and enlargement.

Several factors influence plant growth, including sunlight, water, air, temperature, soil, and nutrients. Sunlight is essential for photosynthesis, the process by which plants prepare their food using carbon dioxide and water. Minerals such as nitrogen, phosphorus, and potassium help in healthy root and leaf development.

Plant hormones also regulate growth and responses to the environment. Proper growth of plants is extremely important because plants provide oxygen, food, medicines, wood, and maintain ecological balance. Thus, plant growth is not only vital for the survival of plants but also for sustaining life on Earth.
