4 major plant parts include - Answer✅✅roots
stems
leaves
reproductive parts
4 functions of the root system include - Answer✅✅absorption
anchorage
conduction
storage
2 kind of root systems found in plants are - Answer✅✅fibrous root systems
and
taproot systems
Fibrous root system - Answer✅✅root 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) - Answer✅✅root 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? -
Answer✅✅Spread the roots out or prune them to encourage the root system to
grow outward
3 primary functions of the stems are - Answer✅✅Support
conduction
storage
Conduction - Answer✅✅the movement of water, mineral solutions, and substances
manufactured in the plant.
xylem - Answer✅✅water and mineral solution move upward from the roots to the
leaves through inner tissues called
phloem - Answer✅✅manufactured food from the leaves move out of the leaves
through outer stem tissues called
What 2 tissues form the vascular system of the plant? - Answer✅✅xylem and
phloem
Cambium layer - Answer✅✅The tissue between the xylem and phloem is called the
____________. Plant function growth depends on uninterrupted conduction.
Monocotyledonous Plants (single leaf monocots) - Answer✅✅The 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) - Answer✅✅the 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 - Answer✅✅is a complete circle of dead tissue around the stem which
interrupts the food supply pipeline.
Nodes and internodes - Answer✅✅Areas of the stems where leaves emerge are
called ____________ and the space between are called __________.
axillary bud and axil - Answer✅✅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.
Asexual reproductive structures - Answer✅✅Some plants have modified stem and
roots structures that store exceptionally large amounts of food and function as
, Corms, such as gladiolus - Answer✅✅solid stem structures with remains of dried
scale leaves surrounding and protecting them. Cycle of changes are controlled by
temperature.
Rhizome, such as Louisiana - Answer✅✅the main axis or stem of the plant is in a
horizontal position underground
Stolons - Answer✅✅Cylindrical horizontal stems found above ground similar to a
rhizome
Tuberous roots (sweet potato) - Answer✅✅roots that do not have nodes and buds
crown - Answer✅✅the area where the stem and root tissue meets
Biennial Root - Answer✅✅Roots that are living through two growing seasons
Annual Top Root - Answer✅✅Root living through one growing season
October until December - Answer✅✅Outdoor planting of spring bulbs can be done
from
Dicot Leaf - Answer✅✅Leaf that generally has netted venation, one or more
prominent veins with branches forming a conspicuous net
Mono Leaf - Answer✅✅Leaf that generally has parallel veins with inconspicuous
branching between the veins as in corn
Photosynthesis and transpiration - Answer✅✅Leaves have two main functions to
carry out: ______________ and _______________.
Photosynthesis - Answer✅✅the 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 - Answer✅✅the 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 - Answer✅✅What occurs when transpiration is
more rapid than absorption?
Lower water pressure at the TOP of the plant - Answer✅✅Water movement from
the roots through the stems to the leaves depends on
Angiosperms - Answer✅✅Plants that bloom and develop fruit which encloses the
seed
