ANSWERS WITH COMPLETE SOLUTIONS
GRADED A+
QUESTIONS AND ANSWERS
Biodiversity. ANSWER -Diversity found in organisms and life.
Phylogeny. ANSWER -Tracing evolutionary history of organisms.
Systematics. ANSWER -Classification of organisms according to relationships based
on phylogeny.
Gamete. ANSWER -Two cells (egg and sperm) fuse together during fertilization.
Alternation of Generation. ANSWER -Alternation between sexual and asexual phase
in the life cycle of an organism.
Photoautotroph/Photosynthetic. ANSWER -An organism that produces its own food
via a light source.
Heterotrophic. ANSWER -Organisms that get food by consumption, not light.
Mixotrophic. ANSWER -Organisms that can use both photoautotrophic and
heterotrophic means to get food.
,Primary Endosymbiosis. ANSWER -Origin of mitochondrion and chloroplast in cells.
Secondary Endosymbiosis. ANSWER -Ingestion of red and green algal cells to form
several different protists.
Super Groups. ANSWER -The kingdom Protista is broken into four groups;
somewhat remedied the flaw in organizing the Protista kingdom. (there are Excavata,
SAR (broken into three groups), and Archaeoplastida).
Pellicle of Euglena. ANSWER -Instead of a cell wall, Euglena is surrounded by a
pellicle (coat) of protein.
Kineto Plastids. ANSWER -A group of Protists; within the group Euglenosa, which is
in the Super Group Excavata.
Alveoli. ANSWER -Membrane bound sacs under a plasma membrane.
"Hairy Flagellum" of Stramenopile. ANSWER -A flagellum with hair-like
appendages; unique to the group Stramenopile.
Heterokont. ANSWER -Another word for Stramenopiles.
Phytoplankton. ANSWER -A protist that is photosynthetic; have some plant-like
characteristics.
Red Tide. ANSWER -An effect of an algal bloom (characteristic of Dinoflagellates)
, Sporozoite. ANSWER -An infectious stage caused by Apiocomplexans; they are the
cells released by these organisms that infect the hosts.
Apical Complexes Organelle. ANSWER -The organelle that penetrates and infects
host cells.
Apicoplast. ANSWER -A non-photosynthetic plastid.
Cilia. ANSWER -Appendages on the outside of a cell used for locomotion and feeding.
Are often smaller than flagella.
Macronucleus. ANSWER -A nucleus that functions mostly as a normal nucleus in
Ciliates.
Micronucleus. ANSWER -A nucleus that functions in sexual and asexual
reproduction in Ciliates.
Conjugation. ANSWER -The process where two compatible Ciliates join together in
sexual reproduction.
Hypha. ANSWER -A filamentous growth. In fungi, they are fragments of filamentous
growth.
Absorption. ANSWER -A mode of nutrition in some Ciliates.
