In flowering plants, plasmodesmata are narrow channels through cell walls that connect the cytoplasms of adjacent cells. An explanation of how plant cells communicate across cell walls will most likely refer to the diffusion through plasmodesmata of which of the following?a) Membrane-bound organellesb) Condensed, duplicated chromosomesc) Branched polysaccharidesd) Small, water-soluble molecules

Option-D

Explanation:

Plasmodesmata are the plasma membrane lined pores present in the cells of the plants. Inside these pores runs a closed tubelike structure which is an extension of the endoplasmic reticulum.

The plasmodesmata allows cell to cell communication which involves symplast mode of transport that is through its cytoplasm.

The small water soluble molecules like amino acid and sugars can easily pass through these plasmodesmata via diffusion. The large molecules can be transported through these plamodesmata through selective diffusion.

Thus, Option-D is the correct answer.
