In which particular location phloem occur in bicollateral vascular bundles?
In which particular location phloem occur in bicollateral vascular bundles?
The correct option is A On both sides of xylem
Collateral: in this type, xylem and phloem are arranged side by side on the same radius. This may be either open or closed. Usually xylem is seen towards the inner side and phloem towards outer side collateral open: Xylem towards the inner side and phloem towards the outer side. In between xylem and phloem, cambium is present. This type of vascular bundle is collateral Open. Example: Dicot stem.
Collateral closed xylem towards the inner side and phloem towards the outer side. In between this, there is no cambium. Therefore, the vascular bundle is called collateral closed example: Monocot stem.
Bicollateral: Here two patches of phloem is found on either side of xylem at the middle. This types o vascular bundles found in members of family Cucurbitaceae, Solanaceae, Convolvulaceae.
