Fibrous Root System
A root system common to monocots consisting of a mat of thin roots spreading out below the soil surface.
the woody part of plants: the supporting and water-conducting tissue, consisting primarily of tracheids and vessels
vascular tissue responsible for the transport of nutrients and the carbohydrates produced by photosynthesis
single layer of cells that form a waterproof seal around a root's vascular tissue; controls the flow of water and dissolved ions into the root
A water-impermeable ring of wax in the endodermal cells of plants that blocks the passive flow of water and solutes into the stele by way of cell walls.
Fatty material found in the cell walls of cork tissue and in the Casparian strip of the endodermis
A layer of cells just inside the endodermis of a root that may become meristematic and begin dividing again.
A waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants.
The ground tissue of a leaf, sandwiched between the upper and lower epidermis and specialized for photosynthesis.
the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move
