(pg 3, FCHP)
Primary Growth - Answer -The type of growth occurring from Apical Meristems
(pg 3)
Primary Growth - Answer -The type of growth that results in the elongation of shoots and roots
(pg 3)
Apical Meristem - Answer -The meristem located at the tip of a shoot or a root.
a.k.a. Primary Meristem
(singular)
,(pg 4)
Secondary Growth - Answer -The type of growth occurring from secondary meristems.
(pg 4)
Secondary Growth - Answer -The type of growth that results in the widening / increase in diameter of
stems, branches, and roots.
(pg 4)
Secondary Growth - Answer -The type of growth that produces the wood of trees
(pg 3 & 4)
Secondary Meristem - Answer -The type of meristem that produces Secondary Growth
a.k.a Lateral Meristem
(singular)
(pg 3 & 4)
Buds - Answer -House primary meristems in the shoots of a plant.
Can be lateral or terminal. Can develop into a shoot or a flower
(plural)
(pg 4)
Stipules - Answer -Modified leaves (differing in function from true leaves) which serve to protect the
buds meristematic region and any developing shoot growth
(plural)
(FCHP)
, Root Cap - Answer -Overlapping scales which help protect the apical meristem of roots
(singular)
(pg 4)
Cambium - Answer -The first type of Secondary (lateral) Meristem
(pg 4)
Cambium - Answer -A thin sheath of dividing cells (region of mitosis) which produces cells that specialize
in making up the vascular system (vascular tissue) of the plant.
(pg 4)
Cork Cambium - Answer -The second type of Secondary (lateral) Meristem which produces the bark.
(pg 4)
Periderm - Answer -The bark of the tree.
Literally meaning "enclosing skin"
(pg 4)
Cellulose - Answer -The component of the cell wall that provides the cell with its structure. It plays a
large role in providing the framework of different types of cells.
(pg 4)
Lignin - Answer -Provides strength and rigidity to the cell walls of wood in a tree. It helps allow the tree
to grow so tall without collapsing in on itself from its own weight.
(pg 4)
Xylem - Answer -The following are the 4 primary functions of _____:
