Answer 1

What passes through the plasma membrane- and what doesn't- depends on the chemical and physical properties it has. Some membranes allow certain materials to pass while others do not. The speed of which molecules pass the plasma membrane differ due to the size, temperature, pressure, and electrical currents. If the temperature of the water and other molecules were low, or the molecules were bigger, the rate at which they pass through the plasma membrane would be very slow.
Hope this helps!
