Plant cells produce hormones that affect plant growth and behavior. Cytokinins and auxins are two important types of plant hormones. Together, these hormones control cell division in the plant. If cytokinin is high and auxin is low, the plant produces stems. When auxin is high and cytokinin is low, roots grow Plant hormones travel around plants in vessels called xylem. Hormones also move from cell to cell in plants by diffusion or active transport. Where are hormones produced in animals, and how are they transported throughout the body? A. Animal hormones are produced in endocrine glands and travel through the blood.
B. Animal hormones are produced in lymph nodes and travel through the lymphatic system. C. Animal hormones are produced inside the bones and travel through the nervous system. D. Animal hormones are produced in sweat glands and travel through the skin.

Explanation:

Plant hormones are among the most important biochemicals affecting plant growth and yield production under different conditions, including stress. Plant hormones include auxin, abscisic acid, ethylene, gibberellins, cytokinins, salicylic acid, strigolactones, brassinosteroids, and nitrous (nitric) oxide. Plant functioning under stress is affected by plant hormones, which can help the plant to tolerate the environmental stresses. A wide range of actions have been illustrated for plant hormones. If it is possible to regulate the activities of plant hormones under stress, the production of tolerant plant species will be more likely. Soybean [Glycine max (Merr.) L.] growth and activities, including the process of nodulation and biological N fixation with the N fixing bacteria Bradyrhizobium japonicum, are also regulated by plant hormones. The important point about plant hormones is their interactions and cross talk, affecting their activity and efficiency in plants under different conditions, including environmental stresses. Some of the most important findings related to the behavior of the soybean and its symbiotic B. japonicum under environmental stresses as affected by plant hormones are presented.

you should seek treatment when you are seriously thinking of sui.cide, and that can eventually lead to your own death.
