Watery sac containing a high concentration of solutes accounting for up to 90% of a cell's volume.
Vacuolar membrane containing solute-transporting proteins responsible for maintaining osmotic potential
Produced by the procambium and consisting of the pericycle, xylem, and phloem
Organization of vascular tissue in the young stem. Form cylinders in eudicots and are scattered in monocots
Lateral meristem consisting of elongated cells that divide frequently, produces secondary xylem (wood) and secondary phloem
Lateral meristem that supplies the waxy-walled protective cells that go into making bark
Secondary vascular tissue consisting of the cork cambium, cork, and phelloderm (cork on the inside)
Structure composed of the periderm and secondary phloem (all tissues external to the vascular cambium
One or more layers of undifferentiated cells internal to the endodermis that can give rise to and thicken lateral roots and contains transport protiens
Primary meristem that gives rise to the Vascular Tissue System
Innermost region of a root, composed of parenchyma cells and surrounded by xylem and phloem
Form long tubes to transport carbohydrates and other materials. Cells have enlarged plasmodesmata that act as pores.
Water-conducting system composed of vessels laid end-to-end to produce a continuous pipe in angiosperm xylem
Interruptions in the secondary wall that help conduct water and minerals in gymnosperm xylem
Transport (from source to sink) and storage of carbohydrates
Distributes water and mineral ions taken up by roots to the rest of the plant, composed of dead cells
Vascular Tissue System
Transport system inside a plant consisting of xylem and phloem
A continuous meshwork of inter-cellular space and cell walls through which water and solutes can flow rapidly and unregulated
Connected plasmodesmata create a tightly regulated path for water and solutes to flow through
The living contents of a cell (the plasma membrane and everything it contains)
Primary meristem that gives rise to the Ground Tissue System
Primary meristem that gives rise to the Dermal Tissue System
Ground Tissue: Thick cell walls, but no secondary wall. Provide support and the flexibility necessary to bend without snapping.
Ground Tissue: Large vacuole and only a primary wall and a shared middle lamella.Function in photosynthesis and storage. Retain the capacity to divide
Ground Tissue: Thick secondary walls provide support even after death. Composed of Fibers (organized in bundles) and Sclereids ("stone cells"
Ground Tissue System
Virtually all the tissue between the dermal and vascular tissues. Functions in storage, support, and photosynthesis.
Dermal Tissue System
forms the outer covering of a plant, the epidermis
Cytoplasm-filled canals connecting the endoplasmic reticula of adjacent cells that allow direct communication between cells
Innermost layer of cortex, ground tissue
