Yes, glucose can move into the cell through facilitated diffusion using glucose transport proteins on the cell membrane. The concentration gradient allows for passive transport of glucose molecules into the cell.
The statement seems incomplete. Please provide additional information or context so I can better understand the question and provide an appropriate response.
Glucose can move out of a sac via passive diffusion, facilitated diffusion, or active transport, depending on the concentration gradient and the presence of specific transport proteins.
Water does move in semipermeable from high to low because all of the molecules have the need to constantly move around and will move to were ever there is room. so if there is a space with high and a space with low, the molecules in the high will move to the low and even themselves out.

Semipermeable. This type of membrane permits the passage of certain substances while blocking others based on their size, charge, or other characteristics.

No
The sac is called the pericardial sac. The snake's heart can move 1 to 1 1/2 inches because of this sac.
No, osmosis can also occur across a semipermeable membrane between a liquid and a gas. For example, water vapor can move through a semipermeable membrane to equalize the concentration on either side.
Semipermeable means that somethings can pass through a barrier and some things can not. There are many examples: glass in windows allow light but not wind, our cell membranes allow water to move in and out but not proteins or glucose.
