sieve tube's Usage Examples:

This system between the plasmodesmata, companion cells, and sieve tubes allow for the delivery of necessary metabolites.

Sieve tube members are associated with companion cells, which are cells that combine with sieve tubes to create the sieve element-companion cell complex.

The main functions of sieve tube members include maintaining cells and transporting necessary molecules with the help of companion cells.

restricted to the phloem tissue where they can move and multiply through the sieve tube elements.

The two types of sieve elements, sieve tube members and sieve cells, have different structures.

Plasmodesmata connect companion cells to sieve elements and parenchyma cells can connect the sieve tubes to various tissues within the plant.

Although the function of both of these kinds of sieve elements is the same, sieve cells are found in gymnosperms, non-flowering vascular plants, while sieve tube members are found in angiosperms, flowering vascular plants.

A longer-term solution to wounded sieve tube elements involves the production of callose at the sieve pores.

fluid transported in xylem cells (tracheids or vessel elements) or phloem sieve tube elements of a plant.

By having the assistance of these pores that constitute a majority of the structure of sieve plates, the diameter of the sieve tubes can be regulated.

The major difference between sieve cells and sieve tube members is the lack of sieve plates in sieve cells.

Hartig was the first to discover and name the sieve tube element cells (as Siebfasern - sieve fibres and Siebröhren - sieve tubes).

Structurally, the walls of sieve tubes tend to be dispersed with plasmodesmata grouped together and it is these areas of the tube walls and plasmodesmata that develop into sieve plates over time.
