Question

Which of the choices are correct comparisons between gap junctions and plasmodesmata? Select all that apply.

Gap junctions connect cells directly at the plasma membranes, but plasmodesmata must also bridge the cell wall separating the two cells.

Both allow exchange of material between cells, but gap junctions allow larger-sized molecules to transfer between cells.

Animal cells have gap junctions, and plant cells have plasmodesmata.

In plasmodesmata, the plasma membranes of the connected cells are continuous, whereas in gap junctions, the plasma membranes of the connected cells remain distinct.

Answer 1

ANSWER :

The correct choices are-

Gap junctions connect cells directly at the plasma membranes ,but plasmodesmata must also bridge the cell wall seperating the two cells (REASON- Since plasmodesmata are present in plant cells and gap junctions are possesed by the animal cells , animal cells do not have any cell membrane , but plants have and hence they need some kind of channels that would make connection or bridge the adjacent cells)

Animal cells have gap junctions and plant cells have plasmodesmata.
