A Virus does not have a semipermeable membrane around it , that is why, it does not use it.
A selectively permeable cell membrane allows certain molecules or ions to pass through it by means of active or passive transport. The most common example is the phospholipid bilayer cell membrane that surrounds all of our body cells. The inner membranes of an egg are also selectively permeable membranes.
Distilled implies boiling, Reverse osmosis implies the use of semi-permeable membranes. I say "implies" because there's a lot of cheating in the bottled water industry.
The porous texture of a sponge made it easier to absorb liquids. (it might work)
Thistle tubes are usually used in experiments involving semi-permeable membranes. Osmosis and diffusion can be illustrated well. Thistle tubes are also used in separation experiments as well as other chemical applications.
The similarity is that they both involve the movement of molecules between a membrane. In osmosis, water diffuses through a semi-permeable membrane without energy due to a difference in solute concentration between sides. In active transport, energy is used by the organism to "push" molecules through ports in the membrane, regardless of solute concentration.
There is no real difference other than the wording; both semi-permeable and partially-permeable mean the ability to allow some substances to pass.However, OCR examiners for AS Biology have said that you should "not use the term semi-permeable when referring to cell membranes that allow water and other solutes to cross them" but should "refer to them as partially permeable."
An impermeable membrane is that through which no substance can pass. Semipermeable membranes are those that let only solvents, like water, to pass through it. Permeable membranes are those that let solvent and solutes, like ions and molecules, to pass across it. There are also selectively permeable membranes, i.e., membranes that besides allowing the passage of solvent, let only some specific solutes to pass while blocking others. See link:

Something that is permeable has pores through which gas or liquid may pass or be absorbed through. An example would be, "A sponge is permeable because it can absorb water." or "Some cellular membranes are permeable."
Selective Media - Our cell membrane has a selective permeable property. This type of membranes are important when we want to allow certain sized particles to enter while restricting other sized particles to enter our cell. Selective permeable membrane is of great use in biological samples.

Osmosis is the diffusion of water molecules from an area of high concentration to an area of low concentration, usually through a semi-permeable membrane.
Evaporation is the most common way but you can also use a fine filter as in a reverse osmosis system. These system use very high pressure and long stacks of semi permeable membrane, like cellophane.
