Question

Differentiate between the open and close type of vascular bundle .​

Answer 1

${ \huge {\boxed {\boxed {\star\: \red{Answer}\: \star}}}}$

Open vascular bundles are the characteristic of dicotyledons (dicots). The cambium present between xylem and phloem is called FASCICULAR CAMBIUM. In closed vascular bundles, the cambium will be absent (fascicular cambium absent) and they do not show secondary growth (closed for secondary growth).

Answer 2

Explanation:

A vascular bundle which is not capable of secondary growth is called a closed vascular bundle. Cambium is absent in closed vascular bundle, example, monocot stem. A vascular bundle which is capable of secondary growth is called an open vascular bundle. Cambium is present in open vascular bundle, example, Dicot stem.
