TERM 2 Food production DEFINITION 2 Roots are involved in all but which of the following activities? TERM 3 Roots DEFINITION 3 An organ that anchors the vascular plant Absorbs minerals and water - Absorption occurs near root tips - Root hairs increase the surface area of the root Stores organic nutrients TERM 4 Stems DEFINITION 4 Consists of: - Nodes - Internodes - Axillary buds - Terminal bud TERM 5 Nodes Internodes Axillary buds Terminal bud DEFINITION 5 - points at which leaves are attached - segment between nodes - potential to form lateral shoot (i.e., branch) - located at shoot tip, causes elongation of a young shoot TERM 6 Leaf DEFINITION 6 the main photosynthetic organ of most vascular plants Consist of : - A flattened blade - The petiole, which joins it to a node of the stem TERM 7 Simple vs. Compounds Leaves DEFINITION 7 Simple leaf : a single , undivided blade - Some may have deep lobes Compound leaf: blade consists of multiple leaflets Doubly compound leaf: each leaflet is divided into smaller leaflets TERM 8 The Three Tissue Systems: Dermal Vascular (xylem and phloem) Ground tissue DEFINITION 8 consists of the epidermis and periderm carries out transport of materials between roots and shoots - conveys water and minerals up from roots - transports organic nutrients form sources to sinks various functions including storage, photosynthesis, and support. TERM 9 Parenchyma DEFINITION 9 - Thin flexible 1 degree cell walls; alive at maturity; carry out most metabolism w/in plant TERM 10 Collenchyma DEFINITION 10 - Unevenly thickened, but flexible 1 degree cell walls; alive at maturity; supports young growing stems
