Hormones in multicellular organisms coordinate growth, development, and responses to the environment. In plants, hormones like auxin are synthesized away from the area of action and diffuse to that area, influencing cellular responses.
What role do hormones play in multicellular organisms for control and coordination, and how are they synthesized and transported within plants?

Hormones in multicellular organisms regulate and coordinate various physiological processes, ensuring homeostasis and adaptive responses to environmental changes. In plants, hormones like auxins, gibberellins, and cytokinins are synthesized in specific tissues such as meristems. Transport occurs through vascular tissues, with auxins exhibiting polar movement. In animals, hormones are synthesized in specialized glands and transported through the bloodstream to target cells. These chemical messengers initiate diverse responses, including growth, metabolism, and stress adaptation. Overall, hormones are key mediators in the control and coordination of biological functions, allowing multicellular organisms to adjust to internal and external stimuli for survival and proper functioning.

Synthesized in specialized glands, they travel through the bloodstream to target cells, eliciting responses. In plants, hormones like auxins, gibberellins, and cytokinins are synthesized in various tissues, including meristems. Transport occurs through vascular tissues, primarily the phloem and xylem. Auxins move predominantly in a polar manner, promoting cell elongation, while other hormones exhibit diverse roles in growth, tropisms, and stress responses. Overall, hormones in both animals and plants play crucial roles in maintaining homeostasis and orchestrating biological processes.
