Question

What is the difference in the arrangement of the vascular bundles in a monocot herbaceous stem and a dicot herbaceous stem? Secondary Growth of Woody Stems Dicot stems contain vascular cambium, which gives rise to new xylem and phloem every year the plant lives. Vascular cambium is lateral mesoderm-when it divides it increases the girth of the plant. In woody plants this increase in girth is quite noticeable, as the diameter of the tree trunk gets larger. This increased size is due largely to the annual rings xylem that build up year after year. of A woody stem has three regions: bark, wood, and pith. The vascular cambium occurs between the bark and t wood. With the help of figure 7.8 and the listing that follows, identify the regions and tissues of a woody stem in a model and/or a slide. How old is the stem you are studying? How do you know? he

3.phloem parenchymas are absent

4.water containing cavity present

5.vascular bundles are scattered in ground tissue

#vascular bundle of diacot stem

1.they are of uniform size

2.each bundle is conjoint,collateral/bicollateral and open

3.phloem parenchyma are present

4.no water containing cavity is present
