Summary Introduction
To explain: The difference between a single-celled organism and a single cell of a multi-celled organism.
Concept introduction:
The smallest basic functional unit of life is a cell. Some organisms consist of single cells, which complete all body functioning within one cell. Some organisms consist of multiple cells. They have specific cells for specific functioning. Some cells live and reproduce independently. Others do so as part of a multi-celled organism.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results:
