University of Kentucky BIO 152 Exam 1
UPDATED ACTUAL Exam Questions and
CORRECT Answers
ecosystem services - CORRECT ANSWER - mutualistic relationship between green algae
and land plants
Green Algae Vs. Land Plants(similarities) - CORRECT ANSWER - - photosynthetic
pigments in chloroplast
-arrangement of internal thylakoids
-cell walls, sperm and peroxisomes
-chloroplasts synthesize starch as a storage product
Nonvascular Plants - CORRECT ANSWER - also known as bryophytes. plants that lack
vascular tissue such as moss. Sporophyte is small and short lived and Gametophyte considered
the dominate part of the life cycle because it is long-lived and produces most of the food required
by the individual.
Seedless Vascular Plants - CORRECT ANSWER - have vascular tissue but don't make
seeds. They make microscopic spores that are carried by the wind. sporophyte is mush larger and
longer lived than the gametophyte.
Seed plants - CORRECT ANSWER - have vascular tissue but also contain seeds.
Gametophytes are either male or female but never both.
Seed - CORRECT ANSWER - consists of an embryo and nutrient carrying tissue
Angiosperms - CORRECT ANSWER - flowering plants (group seed plants) Can be either
monocots(one cotyledon) or dicots(two cotyledons).
,Gymnosperms - CORRECT ANSWER - seed plants. Do not have flowers.
Cuticle - CORRECT ANSWER - watertight barrier on plant leaves that resists drying
Sporopollenin - CORRECT ANSWER - waxy material that encases spores and pollen
Stomata(stoma) - CORRECT ANSWER - Openings in plant leaves that allows water to
leave and CO2 to enter.
Guard Cells - CORRECT ANSWER - cells around the stoma that control whether they
open or close
Upright growth importance - CORRECT ANSWER - -transport water from tissues in
contact with wet soil to tissues in contact with dry air.
-becoming rigid enough to avoid falling over in response to gravity and wind.
Lignin - CORRECT ANSWER - a complex polymer built from six-carbon rings and helps
the plant to be rigid and resist falling over.
Tracheids - CORRECT ANSWER - long, thin, tapering cells that contain pits on the sides
and end to allow water to flow through them. Present in all vascular plants.
Tracheids secondary wall - CORRECT ANSWER - contains lignin
Tracheids primary wall - CORRECT ANSWER - contains cellulose
Vessel elements - CORRECT ANSWER - short and wide and found in gnetophytes and
angiosperms. Ends have gaps to increase water efficiency.
, Gametangia - CORRECT ANSWER - protects gametes from drying out in gametophytes.
Alternation of Generations - CORRECT ANSWER - individuals represent a multicellular
haploid stage(gametophyte) or a multicellular diploid phase(sporophyte) and are connected
through the cycle by spores and gametes.
Alt. of Gens. Stage 1. - CORRECT ANSWER - the sporophyte produces spores by
meiosis(haploid).
Alt. of Gens. Stage 2. - CORRECT ANSWER - spores germinate and divide by mitosis to
develop into multicellular haploid gametophytes.
Alt. of Gens. Stage 3. - CORRECT ANSWER - gametophytes produce gametes by
mitosis.
Gametophyte - CORRECT ANSWER - haploid and multicellular.
Gametes - CORRECT ANSWER - haploid and unicellular
Alt. of Gens. Stage 4 - CORRECT ANSWER - two gametes unite during fertilization to
form a diploid zygote.
Alt. of Gens. Stage 5 - CORRECT ANSWER - zygote divides by mitosis and develops
into a multicellular diploid sporophyte.
Spores - CORRECT ANSWER - Haploid produced by mitosis or meiosis that is capable of
becoming a multicellular adult.
Heterospory - CORRECT ANSWER - the production of two distinct types of spores by
different structures found in seed plants. occurs in seed plants
