if there are 4 nodes on a stem, how many internodes are there?
what is 3?
the structure that contains columella cells, which are gravitropic
what is the root cap?
the bundle that inclues both xylem and phloem
what are vascular bundles?
xylem and phloem are distributed evenly across the cross-section, and line the outer most part of the root/stem
the small openings on the stem that allow for gas exchange
what are lenticals?
what type of leaf arrangement has several leaflests surrounding one point on a stem?
the structure that contains waterproof Suberin and blocks water passage between endodermal cells
what is the casperian strip?
the ground tissue cells dead at maturity
what are scerenchyma?
the root/stem that has xylem at the center, bundling to form an "X"
What are herbaceous eudicot roots?
the extension on the leaf that attaches it to the stem
what is the petiole?
the meristematic tissue that gives rise to dermal tissue
what is the protoderm?
the circle of ground tissue found in the cross-section of roots
what is the pith?
what is the epidermis?
xylem and phloem bundles line the outer part of the cross-section, with no bundles in the centered pith
what are herbaceous eudicot stems?
the bud at the top of the plant that makes it grow longer, and has shoot apical meristem
what is the terminal bud?
what a very thin ring on a woody eudicot root can indicate
what is a drought?
The structures formed on the surface of the root when epidermal cells divide outward
what are root hairs?
the meristematic tissue that gives rise to vascular tissue
what is the procambium?
what are monocot roots?
the point of a stem at which a leaf emerged
what is a node?
the polysaccaride produced by the root cap to allow roots to grow with less resistance
what is mucigel?
clusters of meristematic tissue at tips of roots and shoots that allows for primary growth
what is the apical meristem?
small, centered pith is surrounded by concentric rings that age the plant
what are woody eudicot roots?
the angle between the petiole and the stem
what is the axil?
