ANSWERS GET IT 100% CORRECT DETAILED BEST RATED A+ FOR PASS
heteromorphic - CORRECT ANSWERS Referring to a condition in the life cycle of plants
and certain algae in which the sporophyte and gametophyte generations differ in morphology.
holdfast - CORRECT ANSWERS A rootlike structure that anchors a seaweed.
isomorphic - CORRECT ANSWERS Referring to alternating generations in plants and
certain algae in which the sporophytes and gametophytes look alike, although they differ in
chromosome number.
kinetoplastid - CORRECT ANSWERS A protist, such as a trypanosome, that has a single
large mitochondrion that houses an organized mass of DNA.
mixotroph - CORRECT ANSWERS An organism that is capable of both photosynthesis
and heterotrophy.
opisthokont - CORRECT ANSWERS A member of an extremely diverse clade of
eukaryotes that includes fungi, animals, and several closely related groups of protists.
parabasalid - CORRECT ANSWERS A protist, such as a trichomonad, with modified
mitochondria.
producer - CORRECT ANSWERS An organism that produces organic compounds from
CO2 by harnessing light energy (in photosynthesis) or by oxidizing inorganic chemicals (in
chemosynthetic reactions carried out by some prokaryotes).
protist - CORRECT ANSWERS An informal term applied to any eukaryote that is not a
plant, animal, or fungus. Most are unicellular, though some are colonial or multicellular.

radiolarian - CORRECT ANSWERS A protist, usually marine, with a shell generally made
of silica and pseudopodia that radiate from the central body.
red alga - CORRECT ANSWERS A photosynthetic protist, named for its color, which
results from a red pigment that masks the green of chlorophyll. Most are multicellular and
marine.
rhizarians - CORRECT ANSWERS One of the three major subgroups for which the SAR
eukaryotic supergroup is named. Many species in this clade are amoebas characterized by
threadlike pseudopodia.
secondary endosymbiosis - CORRECT ANSWERS A process in eukaryotic evolution in
which a heterotrophic eukaryotic cell engulfed a photosynthetic eukaryotic cell, which survived
in a symbiotic relationship inside the heterotrophic cell.
stipe - CORRECT ANSWERS A stemlike structure of a seaweed.
Stramenopiles - CORRECT ANSWERS One of the three major subgroups for which the
SAR eukaryotic supergroup is named. This clade arose by secondary endosymbiosis and
includes diatoms and brown algae.
test - CORRECT ANSWERS In foram protists, a porous shell that consists of a single
piece of organic material hardened with calcium carbonate.
Unikonta - CORRECT ANSWERS One of four supergroups of eukaryotes proposed in a
current hypothesis of the evolutionary history of eukaryotes. This clade, which is supported by
studies of myosin proteins and DNA, consists of amoebozoans and opisthokonts.

angiosperm - CORRECT ANSWERS A flowering plant, which forms seeds inside a
protective chamber called an ovary.
antheridium - CORRECT ANSWERS In plants, the male gametangium, a moist chamber
in which gametes develop.
apical meristem - CORRECT ANSWERS A localized region at a growing tip of a plant
body where one or more cells divide repeatedly. The dividing cells of it enable a plant to grow
in length.
archegonium - CORRECT ANSWERS In plants, the female gametangium, a moist
chamber in which gametes develop.
bryophyte - CORRECT ANSWERS An informal name for a moss, liverwort, or hornwort;
a nonvascular plant that lives on land but lacks some of the terrestrial adaptations of vascular
plants.
cuticle - CORRECT ANSWERS (1) A waxy covering on the surface of stems and leaves
that prevents desiccation in terrestrial plants. (2) A tough coat that covers the body of a
nematode.
embryophyte - CORRECT ANSWERS Alternate name for land plants that refers to their
shared derived trait of multicellular, dependent embryos.
gametangium - CORRECT ANSWERS Multicellular plant structure in which gametes are
formed. Female ones are called archegonia, and male ones are called antheridia.
gametophore - CORRECT ANSWERS The mature gamete-producing structure of a moss
gametophyte.
