Yes, due to its very small molecular size - unless of course it is frozen.
No, solutes are not always able to diffuse through a cell's selectively permeable membrane. The ability for solutes to diffuse across a membrane depends on the size, charge, and concentration gradient of the solute. Larger or charged molecules may require the assistance of specialized transport proteins to cross the membrane.
A permeable membrane
Diffusion across a membrane in biology is referred to as 'osmosis' & osmosis is the process by which solvent molecules move from a region of high conc. to low concentration and this can therefore occur only in one direction at a time for a perticular solution. this is a really smart answer im surprised
No, the cell wall is not a permeable membrane. It acts as a rigid structure that provides support and protection to the cell, allowing certain substances to pass through pores, but it is not freely permeable like a membrane.
Yes, it is a partially permeable membrane. It allows certain substances like glucose and water molecules to diffuse through but not large molecules like starch and sucrose. Selectively permeable.

Selectively permeable means that only certain substances are able pass through the cell membrane.A selectively permeable membrane is a membrane that only can be permeated by selective things, in other words a surface that lets some molecules in but not others. Like a cell membrane will let water diffuse into it :)

semi-permeable.
Any molecule smaller than the holes in the membrane can pass through is the membrane is permeable. If the membrane is semi-permeable, then only molecules that the membrane selects can pass through. Electronegativity and existence of lipid layers are common selective traits for semi-permeable membranes.

means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell

very complicated question that is better addressed by a cell biology text but in general cell membrane itself is non-polar and allows small non-polar molecules through it also has protein that are built to selectively let in molecule based on commands from the body

The movement of water through a selectively permeable membrane is called diffusion. Water will always diffuse down a concentration gradient, from high solute concentration to low solute concentration.
