Bonus Flashcards
1
Q
What phylum belong to Acoelomate, pseudocoelomate and coelomate
A
Acoelomate: Flat worms
Pseudocoelomate: Roundworms
Coelomate: Molluscs, Annelids, Arthropods, Echinoderms, Chordates (Fluid filled cavity surrounded by mesoderm)
2
Q
Protostomes vs. Dueterostome
A
Mouth forms from blastopore
Anus forms from blatopore
3
Q
Step by step of Plasmodium infection
A
- Mosquito bites and ingests gametocytes
- Gametocytes become male and female and fertilize in mosquito gut
- Zygotes encyst in gut wall
- Zygotes produce haploid Sporozoites
- Sporozoites migrate to salivary glands
- Mosquito bites another person and Sporozoites go to their liver
- Asexual reproduction of merozoites in liver cells and move into blood stream
- Blood cells infected with merozoitrs produce more merozoites and/ or develop into gametocytes
4
Q
Trypanosome Cruzi lifecycle
A
- Bug bites human
- Amastigotes develop in body
- Trypanomastigotes released into blood
- Lose flagella to become amastigotes to reproduce
- Become trypanomastigotes in blood until bug eats them
- Multiples in bug gut
- Alternative or definite host
5
Q
Schistosomiasis lifecycle
A
Class Trematoda
- Cercariae swim and bore through skin of human
- Cercariae migrate to hosts intestine and form adult flukes
- Encapsulated embryos released in feces
- Miracidia hatch in freshwater
- Miracidia burrow into snail
- Mother sporocysts develop in snail and produce daughter sporocysts
- Cercariae emerge from daughter sporocysts and break out of snail
- Cercariae are in water until humans
6
Q
Hemimetabolous vs Holometabolous step by step
A
- eggs-molt-molt-molt-molt-molt-molt and metamorphosis-adult
- eggs-molt-molt-molt-molt-molt and pulsation-pupa-metamorphosis-adult
7
Q
Insect mouth parts functions
- labrum
- mandible
- maxilla and maxillary palp
- labium
- labial pal
- hypopharynx
A
- upper lip
- hard, powerful cutting jaws
- pincers; less powerful
- 5 segmented palp for taste
- lower lip
- 3 segmented sensory palp
- tongue-like structure in floor of mouth that discharges saliva
8
Q
Maxillipeds
A
Appendages modified for feeding, between maxillae pair in crustaceans and Myriapodans
9
Q
Chelicerae
A
Mouth part (jaws) of chelicerata that can be modified as claws or fangs
10
Q
Madreporite
Ampullae
Papule
Functions
A
- entry and exit point of sea water; control water levels in WVS
- pouch or sack that expands/ contracts to move water up or down each tube foot
- projections of coelom of Asteroidea that serve in reputations and waste removal
11
Q
Parapodia
Setae
Functions
A
- muscular bristle-bearing appendages used in locomotion, sensation and respiration
- prevent sliding backwards/ attachment
