Final answer:
True, long distance signaling in cell-to-cell communication requires hormones in both plants and animals. Hormones facilitate communication between distant cells or organs by coordinating physiological processes.
Step-by-step explanation:
True, long distance signaling in cell-to-cell communication does require hormones in both plants and animals. In both kingdoms, hormones are involved in coordinating various physiological processes and facilitating communication between distant cells or organs.
For example, in plants, hormones such as auxins, cytokinins, and gibberellins are responsible for regulating growth, development, and response to environmental stimuli. These hormones are produced in one part of the plant and then transported to target tissues in other parts, allowing the plant to respond to changes in light, gravity, and other factors.
In animals, endocrine hormones are secreted by various glands and are carried by the bloodstream to different parts of the body. Hormones like insulin, adrenaline, and estrogen play critical roles in coordinating metabolism, stress response, and reproductive processes.
