For multicellularity to develop, there must be a mechanism of signaling among cells in the multicellular organism. Which of the following structures present in the cell membrane receives signals from the environment, or other cells?
A)plasmodesmata
B)receptors
C)gap junctions
D)cadherins

Question

Quizplus · Accepted Answer

Receptors on the cell membrane receive signals from the environment or other cells. Plasmodesmata are channels between plant cells, gap junctions are channels between animal cells, and cadherins are proteins that help connect cells to neighboring cells. While all of these structures are important for multicellularity, they do not serve the function of receiving signals from the environment or other cells.
