Cards

Term
Shoots
Definition
Above ground plant parts such as stems, leaves, and flowers
Term
Roots
Definition
Structures that absorb water and dissolved minerals
Term
Ground Tissue System
Definition
Stores materials, functions in photosynthesis, and structurally supports the plant
Term
Monocots/Eudicots
Definition
Consist of the the same tissue organized in different ways
Term
Cotyledons
Definition
Leaf-like structures that contain food for a plant embryo (Eudicots have 2, Monocots have 1)
Term
Meristems
Definition
Regions of rapidly dividing cells
Term
Apical Meristem
Definition
Provides primary growth (lengthening)
Term
Lateral Meristem
Definition
Provides secondary growth (thickening)
Term
Parenchyma
Definition
Simple plant tissue that makes up most of the the primary growth
Term
Collenchyma
Definition
Simple plant tissue that supports growing plants parts
Term
Sclerenchyma
Definition
Simple plant tissue that contains lignin for support
Term
Mesophyll
Definition
Photosynthetic parenchyma
Term
Sieve-tube Members
Definition
Interconnect to form tubes that conduct sugar
Term
Companion Cells
Definition
Load sugars into the sieve tubes
Term
Epidermis
Definition
Covers and protects the outer surface of primary plant parts
Term
Periderm
Definition
Replaces epidermis on woody plants because they have extensive secondary growth
Term
Vascular Bundles
Definition
Vascular tissue threaded through ground tissue
Term
Terminal Buds
Definition
A shoot's main zone of primary growth
Term
Lateral Buds
Definition
Forms the side branches and leaves of a flower
Term
Veins
Definition
Vascular bundles in leaves that contain the xylem and phloem
Term
Vascular Cylinder
Definition
Sheathed, cylindrical array of primary xylem and phloem in a root
Term
Root Hairs
Definition
Increases the surface area of the leaf's epidermis to increase absorption
Term
Taproot System
Definition
In eudicots, a primary root and all of its lateral branchings
Term
Fibrous Root System
Definition
Root system composed of an extensive mass of similar-sized roots; typical of monocots
Term
Vascular Cambium
Definition
Produces secondary xylem on inner surface and secondary phloem on outer surface
Term
Cork Cambium
Definition
Inner xylem expansion that ruptures the outer secondary phloem
Term
Bark
Definition
Secondary phloem and periderm
Term
Heartwood
Definition
Old xylem clogged with metabolic waster
Term
Sapwood
Definition
New xylem between heartwood and vascular cambium that has a functional xylem
