KU Biol 152 Exam 2 Questions and
Answers
Which one of the following statements regarding evolutionary relationships among land
plants is correct? - Correct Answers -Bryophytes and vascular plants together form a
monophyletic group; vascular plants diverged more recently; the ancestor of all land
plants was green alga
One of the earliest evolutionary adaptations that helps plants retain water in a terristrial
environment - Correct Answers -the cuticle
which one of the following are produced by roots in order to increase surface area,
allowing for greater access to nutrients in the soil? - Correct Answers -root hairs
Which of the following are the major groups of vascular plants - Correct Answers -
angiosperms, lycophytes, gymnosperms, ferns and horsetails.
spores - Correct Answers -haploid cell produced via meiosis in the sporangium of the
sporophyte.
Ovule - Correct Answers -plant structure that develops into a seed when fertilized
Pollen - Correct Answers -fine powdery substance, typically yellow, consisting of
microscopic grains discharged from the male part of a flower or from a male cone.
Seed - Correct Answers -the grains or ripened ovules of plants used for sowing: the
fertilized ripened ovule of a flowering plant containing an embryo and capable normally
of germination to produce a new plant
Endosperm - Correct Answers -nutritive tissue surrounding the embryo within seeds of
flowering plants. A tissue found in many seeds which supplies nutrients to the embryo.
How do vascular plants differ from mosses - Correct Answers -They have a dominant
gametophyte life cycle and lack vascular tissue
Plants loose a great deal of water from their leaves - Correct Answers -transpiration
Why are maximum rates of water flow higher in angiosperms than in gymnosperms -
Correct Answers -Angiosperms have longer and wider xylem conduits than
gymnosperms
, Why so vascular plants need phloem - Correct Answers -because not all parts of the
plant are photosynthetic
A haploid structure contains ______ and a diploid structure contains _____. - Correct
Answers -One set of chromosomes (1N); Two sets of chromosomes (2N0)
______ are defined as haploid cells that can form gametophytes. Gameopyhtes in turn
produce haploid male and female - Correct Answers -Spores; Gametes; Zygotes
In the cell life cycle of mosses and ferns, which of the following structures are diploid -
Correct Answers -Sporophyte, zygote
Which of the following is (are) used by pollinators - Correct Answers -Nectar and odor
Which of the following statements describes how root meristems differ from apical
meristems - Correct Answers -root meristems are shielded by a root cap that protects
cells from abrasion by the soil.
Within each "unit" composing a shoot of a vascular plant, you would observe leaves
attached at the _____, and large stretch of stem without leaves at the _____. - Correct
Answers -node and internode.
The movement of auxin from the apical to basal sides of immature leaf cells and toward
the xylem and phloem of the stem is an example of_____. - Correct Answers -Polar
transport
A researcher creates a mutant pea plant. What is most likely phenotype of this mutant
pea plant? - Correct Answers -The pea plant would be shorter with more branches
Which of the following statements is true regarding angiosperms? - Correct Answers -
Higher photosynthesis rates, capacity to transport water and take in more O2
Which of the following fruits and vegetables or grains are produced by eudicots -
Correct Answers -Carrots, sunflower seeds, blueberries
All bryophytes are all relatively small. Which one of the following is thought to be the
main limitations - Correct Answers -The male gametes of these land plants are
distributed through the water
Which of the following correctly describes fern we see walking in the woods - Correct
Answers -the diploid Sporophyte
Stoma - Correct Answers -any of the minute pores in the epidermis of the leaf or stem of
a plant, forming a slit of variable width that allows movement of gases in and out of the
intercellular spaces.
