stems
leaves
reproductive parts
4 functions of the root system include - correct answerabsorption
anchorage
conduction
storage
2 kind of root systems found in plants are - correct answerfibrous root systems
and
taproot systems
Fibrous root system - correct answerroot system that consists of numerous multi-
branched roots that are slender; no one root is more prominent than the other.
Tap root system (more difficult to transplant) - correct answerroot system that consists
of one main root that grows directly downward from which branch roots arise;
carrot or a woody root (oak,maple)
What should you do if a plant becomes root bound within their containers? - correct
answerSpread the roots out or prune them to encourage the root system to grow
outward
3 primary functions of the stems are - correct answerSupport
conduction
storage
Conduction - correct answerthe movement of water, mineral solutions, and substances
manufactured in the plant.
xylem - correct answerwater and mineral solution move upward from the roots to the
leaves through inner tissues called
phloem - correct answermanufactured food from the leaves move out of the leaves
through outer stem tissues called
What 2 tissues form the vascular system of the plant? - correct answerxylem and
phloem
Cambium layer - correct answerThe tissue between the xylem and phloem is called the
____________. Plant function growth depends on uninterrupted conduction.

answers
Monocotyledonous Plants (single leaf monocots) - correct answerThe xylem and
phloem tissues are formed in bundles scattered in a discontinuous vascular system
through the stem.
Corn, grass, lilies, orchids
Dicotyledonous Plants (two seed leaves dicots)
Gymnosperms Plants (many seed leaves) - correct answerthe xylem is formed on the
inside next to the heartwood surrounded by a continuous layer of cambium with the
phloem on the outside.
Tree, shrubs, annuals, and perrennials
Girdle - correct answeris a complete circle of dead tissue around the stem which
interrupts the food supply pipeline.
Nodes and internodes - correct answerAreas of the stems where leaves emerge are
called ____________ and the space between are called __________.
axillary bud and axil - correct answerin the angle where each leaf joins the stem, there
is an _________________ which is compressed, dormant stem. The angle is called the
______ of the leaf.
Asexual reproductive structures - correct answerSome plants have modified stem and
roots structures that store exceptionally large amounts of food and function as
Corms, such as gladiolus - correct answersolid stem structures with remains of dried
scale leaves surrounding and protecting them. Cycle of changes are controlled by
temperature.
Rhizome, such as Louisiana - correct answerthe main axis or stem of the plant is in a
horizontal position underground
Stolons - correct answerCylindrical horizontal stems found above ground similar to a
rhizome
Tuberous roots (sweet potato) - correct answerroots that do not have nodes and buds
crown - correct answerthe area where the stem and root tissue meets
Biennial Root - correct answerRoots that are living through two growing seasons
Annual Top Root - correct answerRoot living through one growing season

answers
October until December - correct answerOutdoor planting of spring bulbs can be done
from
Dicot Leaf - correct answerLeaf that generally has netted venation, one or more
prominent veins with branches forming a conspicuous net
Mono Leaf - correct answerLeaf that generally has parallel veins with inconspicuous
branching between the veins as in corn
Photosynthesis and transpiration - correct answerLeaves have two main functions to
carry out: ______________ and _______________.
Photosynthesis - correct answerthe process whereby carbon dioxide and water are
eventually transformed into sugars (glucose) by the living cell using energy from visible
light absorbed by chlorophyll (green pigments)
Transpiration - correct answerthe process whereby the leaf gives off water into the
atmosphere and temperature of the leaf is regulated to reduce injury from excessive
heat build up
water deficit making the plant wilt - correct answerWhat occurs when transpiration is
more rapid than absorption?
Lower water pressure at the TOP of the plant - correct answerWater movement from the
roots through the stems to the leaves depends on
Angiosperms - correct answerPlants that bloom and develop fruit which encloses the
seed
gymnosperms - correct answerplants that have no true flowers or fruit, but bear their
seeds uncovered in cones or similar structures such as conifers
receptacle - correct answerflowers are borne on an enlarged portion of the stem called
the
sepals - correct answerouter set of green floral leaves called __________ enclose the
other parts of the flower until these are nearly mature.
Calyx - correct answercollectively , the sepals comprise the ______.
Corolla - correct answerAn entire set of petals is called the ________.
