Question

what is plasmodesmata and desmotuble...and what are its function.????​

Answer 1

Explanation:

Plasmodesmata (Pd) are co-axial membranous channels that cross walls of adjacent plant cells, linking the3 cytoplasm, plasma membranes and endoplasmic reticulum (ER) of cells and allowing direct cytoplasmic cell-to-cell communication of both small molecules and macromolecules (proteins and RNA).

The desmotubule is a tube of appressed (flattened) endoplasmic reticulum that runs between two adjacent cells. Some molecules are known to be transported through this channel, but it is not thought to be the main route for plasmodesmatal transport.

PLASMODESMATA

Plasmodesmata (singular: plasmodesma) are microscopic channels which traverse the cell walls of plant cells and some algal cells, enabling transport and communication between them.

Function of the Plasmodesmata

Between plant cells, we see the formation of plasmodesmata. A plasmodesma (plural plasmodesmata, singular plasmodesma) is a channel through the cell wall that allows molecules and substances to move back and forth as needed.

DESMOTUBLE

Desmosomes are intercellular junctions that provide strong adhesion between cells. Because they also link intracellularly to the intermediate filament cytoskeleton they form the adhesive bonds in a network that gives mechanical strength to tissues.
