BIOL 110 - UNIVERSITY OF
WATERLOO EXAM QUESTIONS AND
ANSWERS
Animal - Correct Answers -eukaryotic, heterotrophy and lacking a cell wall
cellular grade of organization - Correct Answers -cells are specialized part of entire
organism; kids sports team
cell-tissue grade of organization - Correct Answers -specialized cells work together as
an organized unit, for a common function
tissue-organ grade of organization - Correct Answers -tissues grouped together as a
unit for a common function
organ-system grade of organization - Correct Answers -organs working together for a
common function; highest level of organization
Phylogeny - Correct Answers -a hypothesis of the evolutionary history of a group of taxa
Phylogeny Trees - Correct Answers -depict a timeline of animals and their common
ancestors
Clade - Correct Answers -a group of organisms hypothesized to have evolved from a
common ancestor
Genetic Revolution - Correct Answers -the focus has been moved from just morphology
to genetic sequencing
naupulius - Correct Answers -a free-swiming microscopic larval stage in crustaceans
molting - Correct Answers -shedding the outter cuticle layer
epicuticle - Correct Answers -thin waxy texture, no chitin
Holozoic feeding - Correct Answers -phagocytosis; cell eating
Saprozoic Feeding - Correct Answers -pinocytosis; cell drinking
, Mutalistic - Correct Answers -two different species derive benefit from their association;
may be necessary for both
Commensualistic - Correct Answers -one organism lives close to or on another
organism and benefits; the host is unaffected
Parasitic - Correct Answers -the condition of an organism living in or on anothe rat
whose expense the parasite is maintained
Undulipodia - Correct Answers -Eukaryotic flagella and cilia; differ in size and function
Flagellum - Correct Answers -whip-like organelle; used for locomotion
Pseudopodia - Correct Answers -a temporary cytoplasmic protrusion extended out from
an ameoboid cell
Cilia - Correct Answers -a hair-like, vibratile organelle process; used in moving particles,
or locomotion.
Gametes - Correct Answers -mature haploid sex cell; egg or sperm
Schizogeny - Correct Answers -multiple asexual fission
Sporogony - Correct Answers -multipple fission to produce sporozoites after zygote
formation
Lobopodia - Correct Answers -pseudopodia that forms lobes
Filopodia - Correct Answers -pseudopodia that does not branch out
Reticululopodia - Correct Answers -pseudopodia that forms interconnecting nets
axopodia - Correct Answers -pseudopodia that is long and straight with no net
definitive host - Correct Answers -parasite reaches sexual maturity; host is generally not
killed by the parasite (mosquito) -sexual reproduction
intermediate host - Correct Answers -juvenie stages of the parasite occur here; host is
often killed or severely injured (humans) -no sexual reproduction
osculum - Correct Answers -excurrent opening in a sponge (porifera)
spicule - Correct Answers -one of the minute calcareous or siliceous skeletal bodies
found in sponges
mesohyle - Correct Answers -gelatinous matrix surrounding sponge cells
