NEET BIOLOGY

Detailed explanation-1: -Plasmodesmata (Pd) are co-axial membranous channels that cross walls of adjacent plant cells, linking the 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).

Detailed explanation-2: -Plasmodesmata connect cytoplasms of adjacent cells by traversing the cell wall. Appressed endoplasmic reticulum, called the desmotubule, runs through the plasma membrane-lined pore. Molecules move via the cytoplasmic sleeve between the desmotubule and plasma membrane.

Detailed explanation-3: -Plasmodesmata (singular: plasmodesma) are microscopic channels which traverse the cell walls of plant cells and some algal cells, enabling transport and communication between them.

Detailed explanation-4: -Plasmodesmata are intracellular cytoplasmic connections that help in cell to cell communication. They are found as small pores or tunnels in the middle lamella, that extend up to the cell cytoplasm.

Detailed explanation-5: -Plasmodesmata are the microscopic channels that traverse the cell walls of plant cells and allow transport and communication between the adjacent cells. They connect the cytoplasm of neighboring cells causing an exchange of materials and communication between the cells. They are generally present in plant cells.
