water

If a solution outside of a cell has a lower concentration of solutes inside of a cell, it is referred to as what?

hypotonic

facilitated

hypertonic

isotonic

In an electron microscope, what type of cells are used?

dead, but fresh cells

live and fresh cells

dead, processed cells

live, processed cells

Which model best describes the observations and functions of the plasma membrane?

phospholipid bilayer

cell membrane

fluid mosaic model

nuclear envelope

Explanation / Answer

Water is the substance involved in osmosis. It is defined as the movement of liquid solvent through semi permeable membrane from high solute concentration to low solute concentration. While the liquid can be any solvent, term osmosis is closely associated with water.

Hypotonic solution has concentration of solute greater inside the cell than outside. This leads to turgidity and bursting of cells.

Electron microscope uses dead but fresh cells.

Fluid mosaic model is the most accepted model of plasma membrane. It describes the quasi fluid structure of plasma membrane.
