WSU BIOLOGY 106 EXAM 1 ACTUAL EXAM 2 LATEST VERSIONS
(VERSION A & B) ACTUAL EXAM
Three basic plant organs - ANSWER: roots, stems, leaves
roots - ANSWER: Absorbs water and minerals from the ground. Anchors plant in
ground.
Stems - ANSWER: Carry substances between roots and leaves; provide support for
plant; holds leaves up to sunlight
leaves - ANSWER: The main photosynthetic organs of vascular plants.
Nodes - ANSWER: the points at which leaves are attached
internodes - ANSWER: the stem segments between nodes
axillary bud - 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 - ANSWER: bud at tip of a stem responsible for terminal growth
petiole - ANSWER: The stalk of a leaf, which joins the leaf to a node of the stem.
Three plant tissues - ANSWER: dermal, vascular, ground
dermal tissue - ANSWER: tissue of the plant that makes up the waxy outer layer of
the plant
vascular tissue - ANSWER: Plant tissue consisting of cells joined into tubes that
transport water and nutrients throughout the plant body.
ground tissue - ANSWER: tissue between the dermal tissue and vascular tissue of a
non-woody plant that functions in photosynthesis, storage, and support
Xylem - ANSWER: vascular tissue that carries water upward from the roots to every
part of a plant
Phloem - ANSWER: Living vascular tissue that carries sugar and organic substances
throughout a plant
parenchyma - ANSWER: Fundamental tissue composed of thin-walled living cells that
function in photosynthesis and storage.
, Collenchyma - ANSWER: type of ground tissue cell with a strong, flexible cell wall;
helps support larger plants
Sclerenchyma - ANSWER: type of ground-tissue cell with an extremely thick, rigid cell
wall that makes ground tissue tough and strong
apical meristem - 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 - ANSWER: A meristem that thickens the roots and shoots of
woody plants. The vascular cambium and cork cambium are lateral meristems.
shoot apical meristem - ANSWER: dome-shaped mass of dividing cells at the shoot
tip
Gymnosperms and eudicots - ANSWER: vascular bundles are arranged in a ring
Monocots - ANSWER: vascular bundles are scattered throughout the stem
secondary growth - ANSWER: Growth produced by lateral meristems, which thickens
the roots and shoots of woody plants.
vascular cambium - 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 - ANSWER: Lateral meristematic tissue that produces the outer
covering of stems
turgor pressure - ANSWER: The pressure that water molecules exert against the cell
wall
turgid - ANSWER: swollen, inflated
flaccid - ANSWER: deflated, limp
apoplastic route - ANSWER: water and solutes move along the continuum of cell
walls and extracellular spaces
Sympoplastic route - ANSWER: transport within the membrane
active transport - ANSWER: Energy-requiring process that moves material across a
cell membrane against a concentration difference
passive transport - ANSWER: the movement of substances across a cell membrane
without the use of energy by the cell
