Top 10 Commonly Confused Words in Insect Physiology

Top 10 Commonly Confused Words in Insect Physiology 1. Exoskeleton vs. Endoskeleton One of the fundamental differences in insect physiology is the presence of an exoskeleton, a hard outer covering, instead of an endoskeleton like in humans. The exoskeleton provides protection, support, and also serves as a site for muscle attachment. 2. Metamorphosis vs. Molting While both metamorphosis and molting involve changes in an insect's body, they are distinct processes. Metamorphosis refers to the complete transformation from larva to adult, as seen in butterflies. Molting, on the other hand, is the shedding of the old exoskeleton to accommodate growth. 3. Oviposition vs. Fertilization Oviposition is the process of laying eggs, a crucial step in an insect's life cycle. Fertilization, on the other hand, refers to the union of male and female gametes, resulting in the formation of a zygote. 4. Pheromones vs. Hormones Pheromones are chemical signals that insects use for communication. They can attract mates, mark territories, or even warn others of danger. Hormones, on the other hand, are chemical messengers within an organism, regulating various physiological processes. 5. Proboscis vs. Mandibles
