Question

For multicellularity to develop, there must be a mechanism of signaling among cells in the multicellular organism. Which of the structures in the cell membrane receives signals from the environment or from other cells?

Answer 1

Receptors

Step-by-step explanation:

The cell membrane has receptors integrated or embedded into to it known as Membrane receptors or trans-membrane receptors . Membrane receptors are specialized proteins and act in cell signalling by receiving extracellular molecules by binding to them.

In multi-cellular organisms cell signalling allows speciation o groups of cells and when the signal is released the membrane receptors are the ones that will receive it.
