Document Summary
35. 1: the plant body has a hierarchy of organs, tissues, and cells: the three basic plant organs (f35. 2, plants draw their nutrients from two very different environments: below ground and above ground, 3 basic organs, roots, stems. Internodes segment between nodes: nodes points at which leaves are attached, auxiliary buds potential to for lateral shoot (branch, terminal bud located at root tip, causes elongation of a young shoot. Leaves (f35. 2: the leaf is the main photosynthetic organ of most vascular plants, consists of, a flattened blade, the petiole, which joins the leaf to a node of the stem, simple vs. 35. 3: primary growth lengthens roots and shoots: primary growth of roots (f35. 13/14, produces the epidermis, ground tissue, and vascular tissue, root cap covers and protects the apical meristems. Includes secondary phloem and periderm: cork cambium, gives rise to the secondary plant body"s protective covering, or periderm, lenticles, areas in the periderm where gas exchange with the outside can occur.
