**Plants can be classified based on how they absorb and circulate materials.
Vascular Plants
1. This is the ___largest___ group in the Plant Kingdom.
2. These plants have a system for transporting _water___and __food____; therefore, they
have true__roots____, __stems___, and __leaves____.
3. Vascular plants have __tube-like__ structures that provide __support__ and help
circulate water and food throughout the plant.
4. _Xylem_____ transport water and minerals from the roots to the rest of the plant.
5. _Phloem____ transport food from the leaves to the rest of the plant.
6. Examples include trees and many shrubs with _woody___ stems that grow very tall and grasses,
dandelions, and tomato plants with _soft__ herbaceous stems.
Nonvascular Plants
7. These plants do _not___ have a system for transporting water and
food; therefore, they do _not_ have true roots, stems, or leaves.
8. They must obtain nutrients directly from the environment and
distribute it from _cell___ to __cell__ throughout the plant. This
usually results in these plants being very __small___ in size.
9. Examples include __mosses_____, liverworts, and hornworts.
**Plants can be classified based on how they reproduce.
Seed-producing
10. Seed-producing plants are plants that reproduce through __seeds_____. Seed
plants make their own seeds.
11. Seeds contain the plant _embryo_____ (the beginnings of roots, stems, and
leaves) and stored food (_cotyledons___) and are surrounded by a _seed__
_coat_. From those seeds, new plants grow.
12. There are two major groups of seed-producing plants: __flowering____ and __cone-bearing_.
Spore-producing
13. Spore-producing plants are plants that produce __spores___ for reproduction
instead of __seeds____.
14. Spores are much __smaller_ than seeds. Almost all __flowerless__ plants produce
spores. Examples include _mosses_____ and ferns.
**Seed-producing plants can be classified based on how they make seeds.
Flowering Plants
15. Flowering plants grow their seeds inside an _ovary_____, which is in a flower.
16. The flower then becomes a __fruit______ containing the seeds.
17. Examples include most ___trees________, shrubs, vines, flowers, __fruits____, and
vegetables.
Cone-bearing Plants
18. Most cone-bearing plants are __evergreen_____ with __needlelike_____ leaves.
19. Conifers never have flowers but produce seeds in __cones_______.
20. Examples include __pine________, spruce, juniper, redwood, and cedar trees.
**Flowering plants can be classified based on the type of seed.
Monocot
21. A seed with _one____ food storage area is called a monocotyledon.
22. Flowers of monocots have either __three____ petals or multiples of three.
23. The leaves of monocots are slender and __long_____ with veins that are
parallel to each other.
24. The vascular tube structures are usually scattered randomly throughout
the __stem_______.
25. Examples include corn, rice, lilies, __grass____, and tulips.
Dicot
26. A seed with __two____ food storage areas is called a dicotyledon.
27. Flowers of dicots have either __four__ or five petals or multiples of these
numbers.
28. The leaves are __wide____ with __branching_ veins.
29. The vascular tubes are arranged in _circular___bundles.
30. Examples include roses, dandelions, beans, maple, and __oak_____ trees.
