Final answer:
Texture, catalyst, surface area to volume ratio
Step-by-step explanation:
Texture
Texture is used to describe how the surface of a colony appears. Common terms used to describe texture include smooth, glistening, mucoid, slimy, dry, powdery, and flaky.
Catalyst
A catalyst is a substance that speeds up the rate of a reaction without being consumed by the reaction itself.
Surface area to volume ratio
The surface area to volume ratio is the comparison of the volume inside a solid to the area exposed on the surface.
