Three basic plant organs - CORRECT ANSWER-roots, stems, leaves
roots - CORRECT ANSWER-Absorbs water and minerals from the
ground. Anchors plant in ground.
Stems - CORRECT ANSWER-Carry substances between roots and
leaves; provide support for plant; holds leaves up to sunlight
leaves - CORRECT ANSWER-The main photosynthetic organs of
vascular plants.
Nodes - CORRECT ANSWER-the points at which leaves are attached
,internodes - CORRECT ANSWER-the stem segments between nodes
axillary bud - CORRECT ANSWER-A structure that has the potential
to form a lateral shoot, or branch. The bud appears in the angle formed
between a leaf and a stem.
terminal bud - CORRECT ANSWER-bud at tip of a stem responsible
for terminal growth
petiole - CORRECT ANSWER-The stalk of a leaf, which joins the leaf
to a node of the stem.
Three plant tissues - CORRECT ANSWER-dermal, vascular, ground
dermal tissue - CORRECT ANSWER-tissue of the plant that makes up
the waxy outer layer of the plant
vascular tissue - CORRECT ANSWER-Plant tissue consisting of cells
joined into tubes that transport water and nutrients throughout the
plant body.
,ground tissue - CORRECT ANSWER-tissue between the dermal tissue
and vascular tissue of a non-woody plant that functions in
photosynthesis, storage, and support
Xylem - CORRECT ANSWER-vascular tissue that carries water upward
from the roots to every part of a plant
Phloem - CORRECT ANSWER-Living vascular tissue that carries sugar
and organic substances throughout a plant
parenchyma - CORRECT ANSWER-Fundamental tissue composed of
thin-walled living cells that function in photosynthesis and storage.
Collenchyma - CORRECT ANSWER-type of ground tissue cell with a
strong, flexible cell wall; helps support larger plants
Sclerenchyma - CORRECT ANSWER-type of ground-tissue cell with an
extremely thick, rigid cell wall that makes ground tissue tough and
strong
apical meristem - CORRECT ANSWER-Embryonic plant tissue in the
tips of roots and in the buds of shoots that supplies cells for the plant
to grow in length.
, lateral meristems - CORRECT ANSWER-A meristem that thickens the
roots and shoots of woody plants. The vascular cambium and cork
cambium are lateral meristems.
shoot apical meristem - CORRECT ANSWER-dome-shaped mass of
dividing cells at the shoot tip
Gymnosperms and eudicots - CORRECT ANSWER-vascular bundles are
arranged in a ring
Monocots - CORRECT ANSWER-vascular bundles are scattered
throughout the stem
secondary growth - CORRECT ANSWER-Growth produced by lateral
meristems, which thickens the roots and shoots of woody plants.
vascular cambium - CORRECT ANSWER-A cylinder of meristematic
tissue in woody plants that adds layers of secondary vascular tissue
called secondary xylem (wood) and secondary phloem.
cork cambium - CORRECT ANSWER-Lateral meristematic tissue that
produces the outer covering of stems
