Quick Summary

A bicollateral bundle is a type of vascular bundle found in plants, specifically within the stem. Unlike a collateral bundle where phloem is only on one side of the xylem, a bicollateral bundle has phloem positioned on both the outer and inner sides of the xylem. This arrangement is characteristic of certain plant families, such as the Solanaceae (potato family) and Cucurbitaceae (cucumber family). Vascular bundles are crucial components of a plant's vascular system, responsible for transporting water, minerals, and food throughout the plant body.12
