what are the 3 main components of a seed? - CORRECT ANSWER seed coat; storage material; embryo
the _____ is a hard outer layer that covers and protects the seed from various external forces - CORRECT
ANSWER seed coat
the _____ stores nutrients for the embryo in a seed - CORRECT ANSWER endosperm
the _____ refers to the first leaves that appear on a seedling - CORRECT ANSWER cotyledon
what are the 4 main parts of the embryo of a seed? - CORRECT ANSWER radicle; hypocotyl; plumule;
epicotyl
the _____ is the part of the embryo that develops into the young root - CORRECT ANSWER radicle
the _____ is the first to emerge from the seed coat, and it anchors the plant into the soil - CORRECT
ANSWER radicle
what makes up the young shoot (things above the soil)? - CORRECT ANSWER hypocotyl, plumule, and
epicotyl
the _____ is the bottom region of the young shoot (above the roots but below the cotyledons) -
CORRECT ANSWER hypocotyl
the _____ develops into the very top region of the young shoot (shoot tip) - CORRECT ANSWER epicotyl
,the _____ is found in between the hypocotyl and epicotyl, and it develops into young leaves - CORRECT
ANSWER plumule
_____ is the sprouting of a seedling from a previously dormant seed - CORRECT ANSWER germination
seeds remain in a state of _____ until environmental conditions are suitable for growth - CORRECT
ANSWER dormancy
what is the most important environmental "cue" that kick starts germination? - CORRECT ANSWER
water
imbibition - CORRECT ANSWER the absorption of water by the seed
_____ is the growth of a seedling into a more mature plant - CORRECT ANSWER development
in plants, growth takes place via repeated cell division/mitosis at the _____ - CORRECT ANSWER
meristems
what are the 2 types of meristem? - CORRECT ANSWER apical and lateral
where are apical meristems located? - CORRECT ANSWER the very tips of roots and shoots
_____ cause the plant to grow vertically - CORRECT ANSWER apical meristems
what is the location and function of lateral meristems? - CORRECT ANSWER found where horizontal
growth can occur
(i.e., lateral meristems function to increase thickness)
lateral meristems include _____ & _____ - CORRECT ANSWER vascular cambium; cork cambium
, where does primary growth occur in a new hatchling? - CORRECT ANSWER apical meristems
_____ cover and protect the apical meristem, so the meristem can further penetrate soil - CORRECT
ANSWER root caps
what are the 3 zones created by apical meristem divisions? - CORRECT ANSWER zone of division; zone of
elongation; zone of maturation
_____ is the vertical growth of a plant at its apical meristems - CORRECT ANSWER primary growth
(zone of division = zone of maturation in this picture)
_____ is the horizontal growth of a plant at its lateral meristems - CORRECT ANSWER secondary growth
what is the vascular cambium? - CORRECT ANSWER a ring of meristematic tissue located between the
primary xylem and primary phloem
cells that are produced on the _____ of the vascular cambium ring become the secondary xylem -
CORRECT ANSWER inside
cells produced on the outside of the vascular cambium ring become the _____ - CORRECT ANSWER
secondary phloem
the _____ forms wood (along with pith) - CORRECT ANSWER secondary xylem
(cells inside the vascular cambium = secondary xylem)
secondary phloem makes _____, which is constantly being shed and replaced - CORRECT ANSWER bark
