Week 9 questions Flashcards
What does the term “arthropod” mean?
Those who have jointed feet
What is their exoskeleton made of, and is this a protein, lipid, or carbohydrate?
Chitin, carbohydrates.
What type of circulatory system do all arthropods have? How do arthropods grow? What does
molting mean?
Open circulatory systems, they molt their skin in order to grow. They shed their chitin shell and become vulnerable with a soft shell.
What are the 2 main sub-phyla of Arthropods? What is the major different characteristic
between the 2 sub-phyla? Name the examples of organisms in each group that were in the class
video.
Cherisoloda (mouth parts move in and out) - spider, mites, ticks
Mandibulate (mouth parts move up and down.) - insects, centipedes, millipedes.
What are examples of animals who are crustaceans? Are they chelicerates or mandibulates?
Describe their specific kidney-type organ, the number of main body plan segments, and their
respiratory organ. Where do they live? (sea, land or air)
crayfish, crabs, lobsters, shrimp. They are mandibulates. They have a green gland by their head. They have 2 body segments. They have gills, they live in water
What are examples of animals who are arachnids? Are they chelicerates or mandibulates?
Describe their specific kidney-type organ, the number of main body plan segments, and their
respiratory organ/structures. Where do they live? (sea, land or air)
spiders, they are chelicerates. Malpighian tubules for respiratory organs. They have book lungs, 3 body segments. They live on land.
What are examples of animals who are insects? Are they chelicerates or mandibulates? Describe
their specific kidney-type organ, the number of main body plan segments, and their respiratory
organ/structure. Where do they live? (sea, land or air)
bees, flies, grasshoppers, butterflies. They are mandibulates. Many spherical openings, 3 body segments. Many trachea (diffusion). They live in air/land.
Which of the three classes of arthropods that we talked about have wings? Do all of the
organisms in that class necessarily have wings?
Insects, they don’t all have wings.
What is metamorphosis? Which class of arthropods that we talked about undergoes metamorphosis?
A change of form in the animals, Insects undergo this.
From lab: What are the 4 main tissue types in vertebral animals, and what are their mane functions?
epithelial tissue (covering and lining surfaces), connective tissue (supporting and connecting other tissues), muscle tissue (contraction for movement), and nervous tissue (transmitting electrical impulses for communication)
What are 2 advantages to having an exoskeleton? What is one disadvantage?
They provide physical protect, site for muscles to attach.
What are at least 6 characteristics that all arthropods
have in common?
Exoskeleton, highly defined segments, motile, Fast reproduction, open circulatory system, Well developed sensory system,
Social behaviors, Complete digestive system
What are the 2 major types of metamorphosis, and how do they differ?
complete and incomplete. complete is 4 stages (egg, larva, pupa, and adult), incomplete is 3 steps (egg, nymph, and adult)
