The process whose specific outcome is the progression of phloem and/or xylem over time, from formation to the mature structure. An example of this process is found in Arabidopsis thaliana. The formation of the principal food-conducting tissue of a vascular plant. The process whose specific outcome is the progression of a tissue over time, from its formation to the mature structure. The process whereby a relatively unspecialized cell acquires specialized features of a sieve cell. A sieve cell is a type of sieve element that has relatively undifferentiated sieve areas (with narrow pores). The sieve areas are rather uniform in structure on all walls; that is, there are no sieve plates. Typical of gymnosperms and lower vascular plants. The sieve element is the cell in the phloem tissue concerned with mainly longitudinal conduction of food materials. The process whereby a relatively unspecialized cell acquires specialized features of a companion cell. The companion cell is the specialized parenchyma cell associated with a sieve-tube member in angiosperm phloem and arising from the same mother cell as the sieve-tube member.
