Plant hormones, also known as phytohormones, are natural chemicals produced by plants that help regulate their growth and development. These hormones control various processes, such as seed germination, flowering, and fruit ripening. They act as signals, allowing different parts of the plant to communicate and respond to environmental changes. There are several types of plant hormones, including auxins, gibberellins, and cytokinins. Each hormone has a specific role; for example, auxins promote cell elongation, while gibberellins help with seed sprouting. By balancing these hormones, plants can adapt to their surroundings and thrive in various conditions.
