Quizplus · Accepted Answer

Pheromones are chemical signals that are used for communication between members of the same species. Hormones, on the other hand, are chemical messengers that act within an individual to regulate physiological processes. Therefore, pheromones differ from hormones in their function and target audience. Options A and D are incorrect because pheromones are not restricted to only plants and fungi, nor are they used for communication between different species. Option B is also incorrect because hormones can act within an individual, whereas pheromones are used for inter-individual communication.
