FFA Floriculture Practice Test

Which of the following is not typically considered a characteristic of an insect?

1. Six legs

2. Exoskeleton

3. Two tentacles

4. Compound eyes

The correct answer is: Two tentacles

Insects are classified in the class Insecta and have defining characteristics that distinguish them from other arthropods and creatures. One of these primary features is having six legs, which is a hallmark of the insect body plan. Insects also possess an exoskeleton, which provides structural support and protection, and compound eyes that enhance their ability to see in various directions and capture movement. The presence of two tentacles is not a characteristic of insects. Instead, insects typically have antennae that are segmented and serve various sensory functions, such as detecting chemicals and movement, rather than being tentacles. Tentacles are more commonly associated with other types of animals, such as cephalopods (like squids) and some mollusks, rather than insects. Thus, identifying two tentacles as an option reflects a misunderstanding of insect anatomy.
