Can you please help me with a simple and short answers please. Also no meed for explanation i just need answers.Thank you o9 1 Wudy steMS Woody stems undergo both primary growth (increase in length) and secondary growth (ncrease in girth). When primary growth occurs, the apical meristem within a terminal the vascular cambium is active. Vascular cambium is meristem tissue, which produces new xylem and phloem called secondary xylem and phloem each year. The buildup of secondary xylem year after year is called wood. Complete Table 19.3 to distinguish between primary growth and secondary growth of a stem. bud is active. When secondary growth occurs, Table 19.3 Primary Growth Versus Secondary Growth Primary Growth Secondary Growth Active meristem Result Observation: Anatomy of a Winter Twig 1. A winter twig typically shows several years' past primary growth. Examine several examples of winter twigs (Fig. 19.12), and identify the terminal bud located at the tip of the twig. This is where new primary growth will originate. During the next growing season, the terminal bud produces new tissues including vascular bundles and leaves. 2. Locate a terminal bud scar. These scars encircle the twig and indicate where the terminal bud was located in previous years. The distance between two adjacent terminal bud scars equals one year's primary growth. 3. Find a leaf scar. This is where a leaf was attached to the stem. 4. Note the vascular bundle scars. Complete this sentence: Vascular bundle scars appear where the vascular tissue 5. Identify a node. This is the region where you find leaf scars and bundle scars. The region between nodes is called an 6. Locate an axillary bud. This is where new branch growth can occur 7.
