Plants grow through a process called photosynthesis, which is the process by which plants use sunlight, water, and carbon dioxide to produce energy in the form of glucose. This energy is then used by the plant to grow and develop.
Plants also require nutrients from the soil, such as nitrogen, phosphorus, and potassium, to support their growth. These nutrients are absorbed by the plant's roots and transported throughout the plant to support various functions, such as cell division and the production of new tissues.
As plants grow, they undergo a process called cell division, in which cells divide and multiply to form new tissues and structures. This growth is regulated by hormones produced by the plant, which control various aspects of growth and development, such as the formation of roots, stems, leaves, and flowers.
Overall, plants grow by taking in sunlight, water, and nutrients from the soil, and using these resources to produce energy and build new tissues and structures.
