1. 4 major plant parts include roots
stems
leaves
reproductive parts
2. 4 functions of the root sys- absorption
tem include anchorage
conduction
storage
3. 2 kind of root systems fibrous root systems
found in plants are and
taproot systems
4. Fibrous root system root system that consists of numerous multi-branched roots that
are slender; no one root is more prominent than the other.
5. Tap root system (more dif- root system that consists of one main root that grows directly
ficult to transplant) downward from which branch roots arise;
carrot or a woody root (oak,maple)
6. What should you do if a Spread the roots out or prune them to encourage the root system
plant becomes root bound to grow outward
within their containers?
7. 3 primary functions of the Support
stems are conduction
storage
8. Conduction the movement of water, mineral solutions, and substances manu-
factured in the plant.
9. xylem

water and mineral solution move upward from the roots to the
leaves through inner tissues called
10. phloem manufactured food from the leaves move out of the leaves through
outer stem tissues called
11. What 2 tissues form the xylem and phloem
vascular system of the
plant?
12. Cambium layer The tissue between the xylem and phloem is called the
. Plant function growth depends on uninterrupted
conduction.
13. Monocotyledonous Plants The xylem and phloem tissues are formed in bundles scattered in
(single leaf monocots) a discontinuous vascular system through the stem.
Corn, grass, lilies, orchids
14. Dicotyledonous Plants the xylem is formed on the inside next to the heartwood surround-
(two seed leaves dicots) ed by a continuous layer of cambium with the phloem on the
Gymnosperms Plants outside.
(many seed leaves) Tree, shrubs, annuals, and perrennials
15. Girdle is a complete circle of dead tissue around the stem which interrupts
the food supply pipeline.
16. Nodes and internodes Areas of the stems where leaves emerge are called
and the space between are called .
17. axillary bud and axil in the angle where each leaf joins the stem, there is an
which is compressed, dormant stem. The
angle is called the of the leaf.

ing and protecting them. Cycle of changes are controlled by tem-
perature.
20. Rhizome, such as the main axis or stem of the plant is in a horizontal position under-
Louisiana ground
21. Stolons Cylindrical horizontal stems found above ground similar to a rhi-
zome
22. Tuberous roots (sweet roots that do not have nodes and buds
potato)
23. crown the area where the stem and root tissue meets
24. Biennial Root Roots that are living through two growing seasons
25. Annual Top Root Root living through one growing season
26. October until December Outdoor planting of spring bulbs can be done from
27. Dicot Leaf Leaf that generally has netted venation, one or more prominent
veins with branches forming a conspicuous net
28. Mono Leaf Leaf that generally has parallel veins with inconspicuous branching
between the veins as in corn

spiration .

the process whereby carbon dioxide and water are eventually trans-
formed into sugars (glucose) by the living cell using energy from
visible light absorbed by chlorophyll (green pigments)

and temperature of the leaf is regulated to reduce injury from
excessive heat build up
