BIO 104 EXAM 2 || ALL QUESTIONS ANSWERED
CORRECTLY.
Three Vegetative plant Organs - or Organ systems correct answers roots, stems, leves
components of shoot system correct answers stem , reproductive shoot (flower), apical bud,
node, internode, apical bud, vegitative shoot, leaf (petiole, blade), axillary bud
Components of the root system correct answers taproot (or main vertical root) and lateral roots,
root hairs, root cap
purpose of roots correct answers plant anchoring
mineral and water uptake
storage
primary root correct answers the first root that emerges from a seed
taproot correct answers A main vertical root that develops from an embryonic root and gives rise
to lateral (branch) roots.
lateral branch roots correct answers a root that branches off of the primary root
root hairs correct answers extensions of root epidermal cells; increase surface area for absorbing
water and minerals
purpose of stems correct answers hold the leaves and bud of the plant
major function is elongation
some stems can perform photosynthesis
consists of alternating nodes where leaves attach
growth is concentrated at the apical bud
purpose of leaves correct answers major photosynthetic organ
exchange gases with the atmosphere
dissipate heat
plant defense
, plant support
plant storage
reproduction
tissue system correct answers dermal tissue, ground tissue, and vascular tissue
Dermal Tisse correct answers a plant's outer tissue covering
protective covering
epidermis
cuticle - waxy outside coating
the periderm
epidermis in roots take in water and minerals
epidermis in shoots is involved in gas exchange
hairlike extensions of the epidermis called trichomes reduce water loss and reflects excess light
in nonwoody plants correct answers the dermal tissue system consists of the epidermis
in wood plants correct answers the dermal tissue consists of the periderm
vascular tissue correct answers facilitates the transport of materials
xylem
phloem
stele
xylem correct answers vascular tissue that carries water upward from the roots to every part of a
plant
two types of cells - tracheids and vessel elements
dead at functional maturity
thickened walls form a vessel for water movement
water migrates laterally through pits of vessels
