Hey!!
Vascular bundles
Vascular bundles-. the distinct structural organization vascular tissues (xylem and phloem) and the formation of vascular bundles is one of the advanced characteristics of higher plants. In the stem of seed plants, the vascular tissue (xylem and phloem) occupy together as vascular bundles. However, in roots the xylem and phloem are not associated together and not form the vascular bundles.
Such an arrangement of vascular tissue in root is called radial arrangement. In the previous post we have discussed theStructure and Classification of Vascular Bundles.
Based on the relative position and number of phloem strands in vascular bundles, the conjoint vascular bundles are classified into two groups:
(1). Collateral vascular bundles and (2) Bicollateral vascular bundles.
(1). Collateral vascular bundle: A type of conjoint vascular bundle where the xylem occupies inner to a single strand of phloem. Example: dicot stem and monocot stem.
(2). Bicollateral vascular bundles:A type of conjoint vascular bundle where the xylem is situated in the middle of two phloem strands. Example: stem of Cucurbita, Cephalandra (members of Cucurbitaceae Family).
