Seed Plants
Chapter 3 Page 88
Question 1
List four
characteristics
common to all seed
plants.
Answer
Seed plants have
roots, stems, leaves,
vascular tissue, and
produce seeds.
Question 2
Compare and
contrast the
characteristics of
gymnosperms and
angiosperms.
Answer
Gymnosperms produce
seeds not protected by
fruit; most have
needlelike, evergreen
leaves. Angiosperms
produce flowers that
become fruits that
enclose seeds.
Question 3
Classify a flower with
five petals as a
monocot or a dicot.
Answer
It is from a dicot.
Question 4
Explain why the root
system might be the
largest part of a plant.
Answer
Roots must absorb
large amounts of
water and nutrients
and anchor plants.
Question 5
Answer
Think Critically: The
cuticle and epidermis
of leaves are
transparent. If they
weren’t, what might
be the result?
Less light would
reach the
chloroplasts, which
would reduce the rate
of photosynthesis.
Question 6
Form a hypothesis
about what substance
or substances are
produced in palisade
cells but not in xylem
cells.
Answer
Hypothesis should
include information
that shows the
connection between
the presence of
chloroplasts in cells
and sugar production.
