    6. Protective Epidermis Cork Cambium

    7. Support & Conductive Xylem (tracheid cells and trachea) Phloem (sieve tubes)

    8. Parts of the Vine These parts may be classified into two groups by the work they perform: Those that carry on vegetative activity Those that produce seed or fruit

    9. Root system 2-5 feet you will find the bulk of the roots. Lateral growth of roots is rarely restricted by natural conditions. Tens of thousands of rootlets are produced by a vine of moderate size. Absorption zone = is the region through which most of the water and mineral nutrients pass in entering the vine.

    10. Shoot system Shoot Growing tip Buds Leaf buds Axillary buds Leaf Blade or lamina Tendrils Lateral shoots Arms Trunk Spur Cane

    11. Shoot Current years growth that arises from the bud.

    12. Growing tip At the end of the shoot is the growing tip, 4-8 inches long, in which new cells are being formed by division and in which elongation is taking place.

    13. Buds Normally develops at each node just above the leaf, in the leaf axil. A bud of a vine usually consists of three partially developed shoots, with rudimentary leaves or both rudimentary leaves and flower clusters.

    14. Leaf buds Is a rudimentary sterile shoot. It will elongate into a shoot that bears only leaves and tendrils.

    15. Axillary buds Usually describes the bud joint between the leaf stem and the shoot.

    16. Leaf Is an expanded, lateral outgrowth of a shoot, arising at a node, and having a bud in its axil.

    17. Blade or lamina Is the expanded or broad, flat part of the leaf.

    18. Tendrils Give physical support to the primary shoots by coiling themselves around anything they come in contact with. **from the point of structure they are looked at as a cluster.**

    19. Lateral shoots Form the canes.

    20. Arms The permanent divisions of the vine, arising from or along the top of the trunk. They bear spurs or canes which are retained for next years production and shoots for this years production.

    21. Trunk The permanent upward stem. It connects the roots to the arms.

    22. Spur Short bearing unit retained during pruning.

    23. Cane Long bearing unit retained during pruning.
