Plant Structure & Function Answers
1. Angiosperms
2. Monocots have one cotyledon
and dicots have two
3. Monocots have petals in
multiples of 3 and dicots have
petals in multiples of 4 or 5
4. Moncots and Dicots
5. Dicots
6. Monocot
7. Dicot
8. Water, carbon dioxide, and
sunlight
9. Roots and shoots
10. The roots are responsible for
anchoring the plant in the soil,
absorbing and transporting
minerals and water for the
plant, and storing food for the
plant.
11. At the top of the plant
12. The terminal buds are where
the plant grows in height.
13. Axial buds are found on the
stem of the plant where the
leaves attach to the stem.
14. It inhibits growth in the lateral
or axial buds.
15. Carrots, beets, turnips, and
potatoes
16. They increase the surface area
of the roots allowing for a
larger area to absorb water.
17. Nodes are where the leaves,
flowers, and other stems attach
to the main stem of the plant.
The space between nodes is
known as internodes.
18. Axial buds are where the plant
is able to grow in width.
19. Removing the terminal bud
removes the Auxin from the
terminal bud, which then stops
the inhibition of growth from
the axial buds.
20. For the storage of
carbohydrates.
21. A stolon is a modified stem that
provides a means for asexual
reproduction.
22. Spines such as those on a
cactus allow for protecting.
Tendrils allow a plant to grasp
as they grow.
23. Central vacuole, chloroplast,
cell wall
24. In the flower
25. Stamen
26. Carpels
27. Pollen is found on the anther of
the stamen.
28. Diploid spores are produced
during meiosis and haploid
gametes are produced during
mitosis
29. Embryo Sac
30. Pollen is transported by
animals or by the wind.
31. In double fertilization one
sperm fertilizes the egg
forming the zygote and the
other sperm is used in the
formation of an endosperm,
which is utilized to nourish the
embryo.
32. The sepal is where the pollen is
produced.
33. The flower petals attract
pollinators.
34. The carpel consists of the
stigma, the style, and the ovary.
It is known as the female
reproductive organ of the
plant.
35. The zygote.
36. Pollen
37. In the ovule
38. Protect the seeds
39. Pollination, petals drop and
ovaries start to grow, ovaries
form the pod.
40. The shoots of dicots develop
into hooks and the shoots of
monocots do not.
41. It is the production of offspring
from a single parent; asexual
reproduction.
42. They contain little genetic
diversity and are therefore
easily wiped out by disease.
43. The loss of water from the
seed.
44. Seed dormancy allows the
plants to stop their maturation
at a certain point and start
again when conditions are
right. One way this can be
controlled is through
hormones.
45. A pineapple is an example of a
multiple fruit made from many
united flowers, whereas a
peach is a simple fruit made
from one flower.
46. They decompose in the soil.
47. Garlic
48. They are better suited for their
immediate environment.
