KU BIOL152 EXAM 2
Which one of the following statements regarding evolutionary relationships among land plants is
correct? - Answer- 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 - Answer- 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? - Answer- root hairs
Which of the following are the major groups of vascular plants - Answer- angiosperms, lycophytes,
gymnosperms, ferns and horsetails.
Plants loose a great deal of water from their leaves - Answer- transpiration
Why are maximum rates of water flow higher in angiosperms than in gymnosperms - Answer-
Angiosperms have longer and wider xylem conduits than gymnosperms
Why so vascular plants need phloem - Answer- because not all parts of the plant are
photosynthetic
A haploid structure contains ______ and a diploid structure contains _____. - Answer- 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 - Answer- Spores; Gametes; Zygotes
In the cell life cycle of mosses and ferns, which of the following structures are diploid - Answer-
Sporophyte, zygote
Which of the following is (are) used by pollinators - Answer- Nectar and odor
Which of the following statements describes how root meristems differ from apical meristems -
Answer- 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 _____. - Answer- 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_____. - Answer- Polar transport
A researcher creates a mutant pea plant. What is most likely phenotype of this mutant pea plant? -
Answer- The pea plant would be shorter with more branches
Which of the following statements is true regarding angiosperms? - Answer- Higher
photosynthesis rates, capacity to transport water and take in more O2
