Question

what is plasmodesmata ? what are its functions in plant cell?

Answer 1

Plant cells are eukaryotic, meaning that they have a membrane-bound nucleus as well as membrane-bound organelles, specialized sub-units inside of a cell. Besides chloroplasts, which are photosynthesis epicenters, another feature that stands out in plant cells is the cell wall. This rigid layer is made up of polysaccharides, or complex sugars, and in some, almost exclusively of the polysaccharide cellulose.

Answer 2

Answer:

Plasmodesmata are minuscule plasma corridors between plant cells which are of paramount importance for transport, communication and signalling between cells. These nano-channels are responsible for the integrated action of cells within tissues and for the subdivision of the plant body into working symplast units.
