The other three statements are false because
Plasma membrane is semipermeable i.e it allows the transport of materials inside and outside the cell.
The proteins in the plasma membrane are integral proteins

Receiving sensory information and carrying commands to the muscles.
Explanation:
The spinal cord serves as the transmission conduit for the passage of action potential as sensory information through the sensory/afferent neurons to the dorsal roots of the spinal cord.The information synapse with the inter neurons,branching off to the brain and emerged as the response through the motor/efferent neurons to the effectors(muscles).
This pathways is called reflex arc. Thus most of the involuntary action of the body is conducted through the spinal cord
