During diffusion, when the concentration of molecules on both sides of a membrane is THE SAME, the molecules will

Which means of particle transport is shown in the picture?

Molecules tend to move from an area of high concentration to low concentration is called

The diffusion of water across a selectively membrane is called

Large molecules, such as glucose, that cannot cross the lipid bilayer can still move across the membrane through a type of PASSIVE transport called

The relatively constant internal physical conditions of an organism is called

Some materials can move across the cell membrane against a concentration gradient by

Cells within a a multicellular organism communicate by chemical signals. In order to receive and respond to a certain chemical signal, a cell must have a ___________ for that chemical

Molecules from inside the cell being expelled out of the cell is known as

What would happen to to an animal cell with an internal salt concentration of 9% if it were placed in a salt solution with a concentration of 3%?

The picture shows an example of what type of solution?

Once equilibrium is reached, equal numbers of molecules move in either directions across a semipermeable membrane.

Proteins called aquaporins are important to the movement of water through cell membranes. These proteins participate in active transport.

Moving materials from an are of LOW concentration to HIGH concentration requires active transport. (against the gradient)
