Arthropods
1. What are some examples of
arthropods?
2. What are the classes into
which the phylum Arthropoda
is divided? What are the three
main ones and some of their
representative species?
3. What are the main
morphological features of
arthropods?
4. Concerning germ layers and
the presence of coelom how
are arthropods characterized?
5. Considering the presence of
segmentation (metameres) in
their body to which other
already studied phylum are
arthropods proximal?
6. What is the external rigid
carapace of arthropods called?
Of which substance is it
made? Which type of organic
molecule is that substance?
7. How do arthropods grow?
8. How does the presence of
exoskeleton explain the
general small size of
arthropods?
9. How can the features of the
arthropod exoskeleton explain
the terrestrial adaptation of
some species of the phylum?
10. What is the type of
digestive system present in
beings of the phylum
Arthropoda? Are these
animals protostomes or
deuterostomes?
11. How is the extra corporeal
digestion associated to
predation in arachnids?
12. Which organs or
respiratory adaptations do
aquatic and terrestrial
arthropods respectively
present?
13. In arthropods why isn't
gas exchange done through
cutaneous diffusion?
14. What is the type of
circulatory system present in
arthropods? Do these animals
have heart and respiratory
pigments?
15. What are respiratory
pigments? What is the
respiratory pigment present in
some arthropods? Which is
the analogous molecule in
humans?
16. How is the respiratory
system of insects (with its
independence between
circulation and respiration)
related to the motor agility of
some species of this arthropod
class?
17. How are the excretory
systems of the three main
arthropod classes constituted?
18. What are the noteworthy
features of the nervous
system of arthropods?
19. What are compound eyes?
20. How is arthropod
reproduction characterized?
21. What are the types of
fecundation that occur in
arthropods? What is the
predominant type?
22. How is fecundation done
in insects (external or
internal)? Is there copulation
between insects?
23. How are the main classes
of arthropods classified
according to the presence of
larval stage in their embryonic
development?
24. What are nymph and
imago?
25. Is the stage when an
insect larva is within a cocoon
a stage of total biological
inactivity?
26. How are the three main
arthropod classes
characterized according to the
presence of wings?
27. Most insects have wings.
Which is the other animal
phylum that contains
creatures with analogous
organs?
28. How are the three main
arthropod classes
characterized according to the
presence of antennae?
29. How are the three main
arthropod classes
characterized according to the
body division?
30. How are the three main
arthropod classes
characterized according to the
number of limbs?
31. Which arthropod class is
the most diversified animal
group of the planet? How can
this evolutionary success be
explained?
32. What are some examples
of beings of the phylum
Arthropoda that present a
high level of behavioral
sophistication?
33. Arthropod identity card.
How are arthropods
characterized according to
examples of representing
beings, basic morphology,
type of symmetry, germ layers
and coelom, digestive system,
respiratory system, circulatory
system, excretory system,
nervous system and types of
reproduction?
