Vascular bundles in leaves; Fig. Xylem and phloem compose vascular tissues, which transport water and dissolved minerals to the photosynthetic tissues through xylem. ADVERTISEMENTS: Vascular bundle is the isolated unit of the longitudinal strands of conducting tissues consisting essentially of xylem and phloem, frequently with a sheath of thick walled cells or other interspersed cells. Each Vascular bundle is conjoint, collateral and closed. The vascular bundle in which xylem and phloem are remain together in such a way that one encloses the other. The lately formed phloem is termed as metaphloem. Xylem vessels are tough and strong, so the vascular bundles are in the centre of the root to resist forces that could pull the plant out of the ground. 5.

Vascular bundles are present in all plant organs, mainly in stem (including rhizomes or underground stems), leaves and roots (including aerial). This is why aphids are typically found on the underside of a leaf rather than on the top, since the sugars manufactured by the plant are transported by the phloem, which is closer to the lower surface.

To maintain an approximately constant number of vascular bundles in such a vascular sys- tem the accessory bundles must either terminate {i.e., disappear from the system) or fuse with an adjacent vascular bundle as in some calamopityans the accessory bundle simply terminates at a higher level. [C] Vascular Bundle: The vascular bundles are irregularly distributed in the spongy parenchyma. Start studying Vascular bundle. ii) There is no cambium present in between xylem and phloem, so these vascular bundles are always closed. Ø It … B. Welcome to BiologyDiscussion!

The abaxial conducting systems consists of an arc of vascular bundles of different sizes that are circular in outline. The phloem transports the photosynthetic products from the leaf to the other parts of the plant. ADVERTISEMENTS: 4. The former two are the characteristic of root and stem respectively while mesarch arrangement is found in the stem bundles of Tmesipteris and ferns. only xylem and phloem. In monocots stem, the vascular bundles are scattered across the stem without any definite arrangement. Phloem parenchymas are absent. 3. In this type of conjoint vascular bundle, phloem is present in two groups, one outside the xylem and the other inside the xylem (i.e., xylem is located between two strands of phloem). The vascular bundles are arranged in three layers, developing unequally at different levels. The position of these bundles varies in different parts of the plant.
