Biology II Chapter 26 Review
| Term | Definition |
|---|---|
| Explain three ways arthropods take in oxygen and give a specific example for each type. | Gills (crayfish); large surface area for gas exchange. Tracheal Tubes (beetle); air enters the through spiracles, travels from tubes to tubules until it reaches muscle. Book Lungs (spider); folded membrane, air from spiracles is transported throughout |
| What are three functions of an exoskeleton? | 1. Provide support, 2. Protects soft body tissues and slows water loss, 3. Provides a place for muscle attachment |
| What are exoskeletons made of and why must they be shed? | Exoskeletons made of chitin and they must be shed because they do not grow with the insect so they must be shed and regrown. |
| How are jointed appendages beneficial to arthropods? Give at least 3 reasons. | 1. Mating, 2. Sensing, 3. Walking, 4. Swimming |
| Many arthropods have a sense organ called a tympanum, what is it used for? | Arthropods use tympanum for hearing. |
| What poisonous spider lives in our area? How is it easily identified? | The poisonous spider that lives in our area is the brown recluse, it can be easily identified by the shape of a violin on its back. |
| Give three characteristics of crustaceans. | 1) 5 pairs of legs, 2) 2 compound eyes, 3) Branched appendages |
| Give three characteristics of spiders. | 1. 6 pairs of jointed appendages, 2. Carnivorous, 3. Can make specific kinds of webs |
| Give three characteristics of insects. | 1. 3 body areas, 2. Legs adapted to environment (Such as legs with claws for digging, sticky pads for climbing, for collecting pollen, etc.), 3. Compound/simple eyes |
| Compare and contrast millipedes and centipedes. | Centipedes move quickly, long, segmented bodies w pair of legs, first pair is poison claws. Millipedes have two pairs of appendages, are herbivorous and do not wriggle quickly, do not have poison claws.Both live in moist environments. |
| Name and explain the four basic types of mouths that insects use for feeding, include example of insects on each. | The four basic types of mouths are: 1. Siphoning (Butterflies) feeding tube 4 liquid, 2. Sponging (Houseflies) mop up food, 3. Piercing/Sucking (Mosquitoes) needle to suck, 4. Chewing (Grasshoppers) mouth brings in food, mandible pieces/cuts food |
| Explain complete and incomplete metamorphosis and give examples of an insect that goes through this process. | Complete metamorphosis (ex: butterfly) is when an insect develops through egg, larva, pupa & adult Incomplete metamorphosis (ex: cricket) is when insects undergo hatching from eggs as nymphs (after several molts, young nymphs become winged adults). |
