Study Notes
Characteristics of Collateral Vascular Bundles
- The main characteristic of a collateral vascular bundle is the arrangement of phloem and xylem on the same radius of the stem.
Arrangement of Tissues
- In a collateral vascular bundle, the phloem is located on the outside and the xylem is located on the inside.
Function
- The function of a collateral vascular bundle is to facilitate the transport of water, minerals, and sugars throughout the plant.
Type of Plant
- Dicotyledonous plants are most likely to have collateral vascular bundles.
Comparison with Bicollateral Vascular Bundles
- A collateral vascular bundle differs from a bicollateral vascular bundle in that it has only one strip of phloem, whereas a bicollateral vascular bundle has two strips of phloem, one on either side of the xylem.
