Biology

35 Terms

1
hermaphrodite
individuals that are male and female
New cards
2
choaocyte
in the interior of spongocoels. cells that are shaped like choanoflagellates, generate current with flagella and help Porifera filter feed by particles getting stuck in the collar
New cards
3
amoebocyte
cells that move through a sponge’s mesohyl which digests food from choanocytes, distribute nutrition, manufacture touch skeletal fibers, and can become other sponge cell types
New cards
4
spongocoel
the pores in the central cavity of a sponge where water is drawn in to filter feed
New cards
5
osculum
a large opening in a sponge where water flows out during filter feeding
New cards
6
gastrovascular cavity
a sac with a central digestive compartment. only has one opening for mouth and anus
New cards
7
cynidocytes
cells that contain cnidae (capsule-like organelles that can expand outward). are on the tentacles of cynrdarians and help capture prey and defend
New cards
8
sessile
organism that stays in one place
New cards
9
nematocyst
specialized cnidae that have a stinging thread and can puncture prey
New cards
10
parthenogenesis
a type of asexual reproduction where females produce unfertilized eggs which are only female
New cards
11
radula
a rough, tongue-like, organ used by Mollusks to scrape up food
New cards
12
complete metamorphosis
metamorphosis where the babies and adults look completely different
New cards
13
incomplete metamorphosis
where babies and adults look similar, just bigger
New cards
14
hemolymph
fluid in open circulatory systems that is propelled by heart into small arteries and then into the hemocoel
New cards
15
hemocoel
the body cavity surrounding tissues and organs
New cards
16
tracheal system
branched air ducts leading into the interior of the body from pores in the cuticle
New cards
17
cuticle
the hard outer covering on Ecdysozoa
New cards
18
spiracle
an external respiratory opening
New cards
19
tube feet
one of the extensions of echinoderm’s water vascular system. function in locomotion and feeding
New cards
20
endoskeleton
an internal skeleton
New cards
21
The two body plans of Cnidarians
floating medusa and sessile polyp
New cards
22
the phylum with most bilateral acoelomates
Platyhelminthes
New cards
23
intermediate and terminal host of a blood fluke
intermediate: snails. definitve/terminal: humans.
New cards
24
three main parts of a mollusk body plan
muscular foot (for movement), visceral mass (main body part with most organs), mantle (layer of tissue over visceral mass that secretes shell)
New cards
25
cephalopods vs. other mollusks
cephalopods have a completely merged head and foot, with a ring of arms and/or tentacles surrounding the head
New cards
26
what is a lophophore and its function?
a hair-like structure that draws in water and food for nutrition
New cards
27
oligochaeta vs. polychaeta
polychaeta have a parapodia which act as little legs and more chaetae (bristles made of chitin) per segment
New cards
28
two evolutionary innovations that are well developed by annelids
the coelom is well developed and complex, and the body is segmented (specialized/ doing different jobs)
New cards
29
three main characteristics of arthopods
segmented bodies, hard exoskeleton, jointed appendages
New cards
30
advantages and disadvantages of arthropod exoskeleton
advantage: gives them durability and protection

disadvantage: limited movement and does not grow with them (molting leaves them exposed)
New cards
31
three major anatomical features of insecta
head, thorax, and abdomen. wings are made from cuticle. 3 pairs of walking legs
New cards
32
crustacea can be distinguished from Insecta by counting their ____
antennae (insects have one pair, crustaceans have two)
New cards
33
what is a barnacle?
a group of mostly sessile crustaceans whose cuticle is hardened into a shell containing calcium carbonate
New cards
34
what two animal phyla exhibit the deuterostome development?
echinodermata and chordata
New cards
35
what anatomical structure is unique to the echinoderms?
water vascular system (its a network of hydraulic canals branching into extensions called tube feet-function in locomotion feeding and gas exchange)
New cards
