Which of the following is a key difference in hormonal regulation between plants and animals, as described in the "Growth and Regulation" section?

  • A: Plant hormones primarily control homeostatic processes, while animal hormones control growth patterns.
  • B: Animal hormones may act locally or be transported throughout the body, whereas plant hormones only circulate globally.
  • C: Plant hormones regulate events like flowering and fruit development, while animal hormones regulate events like molting.
  • D: Both plant and animal hormones act only in specific target tissues and are never transported.

Explanation

The "Growth and Regulation" section specifies: "In plants, hormones may act in a local area or be transported in the body. They control growth patterns, flowering, fruit development, and more. In animals, hormones circulate throughout the body and act in specific target tissues, controlling homeostatic processes and developmental events such as molting." This option correctly distinguishes the specific developmental events regulated by each.
