To determine the missing word, we need to understand the concept being described. The sentence states that "__________ substances can move into or out of cells by diffusion."

Based on this information, we can infer that the missing word should describe the type of substances that can undergo diffusion. Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration.

In the context of cells, substances that can move in or out of cells by diffusion are typically small, non-polar molecules. These molecules are able to pass through the cell membrane without the need for any specialized transport proteins.

Therefore, the missing word in the sentence could be "small," "non-polar," or any other word that describes the characteristics of substances that can undergo diffusion.
