Answer:No

Explanation:

A desmotubule is an endomembrane derived structure of the plasmodesmata that connects the endoplasmic reticulum of two adjacent plant cells.[1][2] The desmotubule is not actually a tubule, but a compact, cylindrical segment of ER that is found within the larger tubule structure of the plasmodesmata pore.[3] Some, but not all, transport of the plasmodesmata occurs through the desmotubule.[4]

A desmosome (/ˈdɛzməˌsoʊm/;[1][2] "binding body"), also known as a macula adherens (plural: maculae adherentes) (Latin for adhering spot), is a cell structure specialized for cell-to-cell adhesion. A type of junctional complex, they are localized spot-like adhesions randomly arranged on the lateral sides of plasma membranes. Desmosomes are one of the stronger cell-to-cell adhesion types and are found in tissue that experience intense mechanical stress, such as cardiac muscle tissue, bladder tissue, gastrointestinal mucosa, and epithelia.[3]

Answer:

Demosomes form links between cells, and provide a connection between intermediate filaments of the cell cytoskeletons of adjacent cells. This structure gives strength to tissues.

Finally, the need for signaling is a function of gap junctions that form pores connecting adjacent cells.
