|
Waxy Cuticle, Large and Numerous. Boundary between the plant and the world. On Stems Leaves and Roots. Single layer of tightly packed cells.
|
Epidermis
|
|
|
The two cells that flank the stomatal pore amd regulate the opening and closing of the pore.
|
Guard Cells
|
|
|
A relatively unspecialized plant cell type that carries out most of the metabolism, synthesizes and stores organic products, and develops into a more differentiated cell type.
|
Parenchyma Cell
|
|
|
A flexible plant cell type that occurs in strands or cylinders that support young prats of the plant without restraining growth.
|
Collenchyma Cell
|
|
|
A rigid, supportive plant cell type usually lacking a protoplast and possessing thick secondary walls strengthened by lignin at maturity.
|
Sclerenchyma Cells
|
|
|
A long, tapered water conducting cell found in the xylem if nearly all vascular plants. Functioning cells are no longer living.
|
Tracheid Cells
|
|
|
A continuous water-conducting micropipe found in most angiosperms and a few nonflowering vascular plants.
|
Vessels
|
|
|
A living cell that conducts sugars and other organic nutrients in the phloem of angiosperms; Connected end to end they form tubes
|
Sieve Tubes
|
|
|
The innermost layer of the cortex in plant roots; a cylinder one cell thick that forms the boundary between the cortex and the vascular cylinder.
|
Endodermis
|
|
|
Plant tissue that remains embryonic as long as the plant lives, allowing for indeterminate growth.
|
Meristem
|
|
|
A cylinder of meristematic tissue in woody plants that adds layers of secondary vascular tissue called secondary xylem (wood) and secondary phloem.
|
Vascular cambium
|
|
|
The outermost layer in the vascular cylinder from which lateral roots arise.
|
Pericycle
|
|
|
The protective coat that replaces the epidermis in woody plants during secondary growth, formed of the cork and cork cambium.
|
Periderm
|
|
|
Growth produced by lateral meristems, thickening the roots and shoots of woody plants.
|
Secondary Growth
|
|
|
Growth produced by apical meristems, lengthening stems and roots
|
Primary Growth
|
