Protophloem vs Metaphloem
Similarities and Difference between Protophloem and Metaphloem

Vascular bundles (fascicles) are the component of the stelar system in higher plants and their main function is the conduction of water, minerals and food materials. Typically, a vascular bundle composed of xylem and phloem arranged together as bundles. In a young stem, both in dicots and monocots, Phloem, the food conducting tissue of vascular bundles, are differentiated into PROTOPHLOEM and METAPHLOEM based on the structural and functional modifications of their elements. The present post describes the similarities and difference between Protophloem and Metaphloem in a primary vascular bundle of a young stem.

Similarities between Protophloem and Metaphloem

Ø  Both protophloem and metaphloem can conduct food materials.

Ø  Both are complex tissues, composed of many types of cells.

Ø  Both components contain living and dead cells.

Ø  Both are developed from the primary meristem, the pro-cambium.

Ø  Protophloem and metaphloem develop only in primary vascular bundles.
