An organism has a variety of organs. For an organism to survive, these organs must be carefully coordinated and managed. The glands of the endocrine system secrete a variety of fluids into an organism’s body. These hormones are in charge of an organism’s general growth and development. The central nervous system is in charge of all other daily decisions, both voluntary and involuntary (CNS).
Every action we take as humans require coordination. Our nervous system takes in information from our environment, processes it, and then triggers a response. The combination of various metabolic processes including reproduction, development, and all reflex movements is facilitated by the endocrine system (hormonal system) (cope uwith various give-up situations).
Plants’ hormone systems aid in photosynthesis, which requires carbon dioxide, water, and sunlight. The hormonal system of the plant body supports the tendrils of climbing plants, the stomatal opening in leaves opens to allow in carbon dioxide gas, the roots bend toward the water, the stem grows toward sunlight, and the tendrils of climbing plants are supported by the tendril system.
Thus, we need a control and coordination system in an organism.
