Can you please help me with a simple and short answers please. Also no meed for explanation i just need answers.Thank you 19.4 Stems Stems are usually found aboveground where they provide support for leaves and flowers. Vascular tissue extends from the roots, through the stem and its branches to the leaves. Therefore, what function do botanists assign to stems in addition to support for branches and leaves? Explain why a branch cannot live if severed from the rest of the plant. Stems that do not contain wood are called herbaceous, or nonwoody, stems. Usually, monocots remain herbaceous throughout their lives. Some eudicots, such as those that live a single season, are also herbaceous. Other eudicots, namely trees, become woody as they mature. Anatomy of Herbaceous Stems Herbaceous stems undergo primary growth. Primary growth results in an increase in length due to the activity of the apical meristem located in the terminal bud (see Fig. 19.2a) of the shoot system. Observation: Anatomy of Eudicot and Monocot Herbaceous Stems Eudicot Herbaceous Stem 1. Examine a prepared slide of a eudicot herbaceous stem (Fig. 19.9), and identify the epidermis (the outer protective layer). Label the epidermis in Figure 19.9. 2. Locate the cortex, which may photosynthesize or store nutrients 3. Find a vascular bundle, which transports water and organie nutrients. The vaso ular bundles in a cudicot herbaceous stem occur in a ring pattern. Label the vascular bundle in Figure 19.9a. Which vascular tissue (xylem or phloem) is closer to the surface? 4. Label the central pith in Figure 19.9a. Pith stores organic nutrients. Both cortex and pith are composed of what type of tissue? Figure 19.9 Eudicot herbaceous stem. The vascular bundles are in a definite ring in this photomicrograph of a eudicot herbaceous stem. Complete the labeling as directed by the Observation. xylom phioem sclerenchyma cells cortex 25x pith b. parenchyma
Explanation / Answer
Additional support to branch and leaves are given by Woody stem which is also a xylem tissue known as Heartwood. A branch can survive if it is grafted on other plant .due to dehydration it can not live.xylem is the tissue which transport water and organic solvent.Xylem is present closer to the surface.Both pith and cortex are made up of ground tissue.
