vascular bundle

Back 28

In plants, a group of longitudinal supporting and conducting tissues (xylem and phloem).

Front 29

phloem

Back 29

The portion of the vascular system in plants consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant.

Front 30

petiole
