Cell Transport

The diffusion of water molecules through a selectively permeable membrane is:

• Homeostasis

• Osmosis

• Active Transport

• Equilibrium

All matter is composed of very small particles called:

• Molecules

• Ions

• Solutes

• Isotopes

The movement of molecules from a place where there is a greater/higher concentration to an area where there is lesser/lower concentration is:

• Homeostasis

• Diffusion

• Endocytosis

• Active Transport

A selectively permeable membrane

• allows all substances to enter and leave

• prevents all substances from entering or leaving

• allows certain size substances to enter and leave

• allows only waste materials to leave

A solution in which the concentration of solutes is the same inside and outside of a cell is a _____________________ solution.

• hypertonic

• hypotonic

• isotonic

• homeotonic

If a red blood cell is placed in a solution that has a concentration gradient higher than the red blood cell, this type of solution is called:

• Isotonic

• Hypotonic

• Hypertonic

• Homeotonic

If a red blood cell is placed in a hypotonic solution, it will eventually

• shrink up

• swell and burst

• no change will occur

• swell and not burst

When substances move in and out of cells using only their own kinetic energy this is called:

• Active Transport

• Passive Transport

• Activation Energy

• Selective Transport

Osmosis is a type of

• turgor pressure

• homeostasis

• active transport

• facilitated diffusion

An example of diffusion is

• water molecules moving into a plant cell after rain

• red food coloring moving through water until the water is pink

• water molecules leaving the cells of a freshwater fish, when placed in a saltwater tank

• none of the above
