The scar left on a twig when a leaf falls. Indicates the amount growth in one year. Tissue in the vascular system of plants that move dissolved sugars and other products of photosynthesis from the leaves to other regions of the plant. Cells of the vascular system in plants that transport food from leaves to other areas of the plant. Flower bud The stem region of a plant where one or more leaves attach. Where leaves are attached to stems. Node Space between nodes 10/14/2018 Unit 3, Lesson 7, terms 1

Tissue in the vascular system of plants that moves water and dissolved nutrients from the roots to the leaves. Plant tissue type that conducts water and nutrients from the roots to the leaves. A corky spot on the bark which originally permitted air to enter the twig. Leaf scar Terminal bud Lenticels Xylem Phloem Pith Cambium 10/14/2018 Unit 3, Lesson 7, Terms 2

Leaves that cover the outside of the bud. A lateral meristem in plants. Types include vascular, cork, and intercalary. Leaves that cover the outside of the bud. Central area in plant stems, largely composed of parenchyma tissue modified for storage. Located at the end of the plant shoot. Axillary or lateral bud Born in the axil (where the leaf meets the stem) of a stem. Internode Growth Rings 10/14/2018 Unit 3, Lesson 7, Terms 3
