Final answer:
When an agar plate is streaked correctly, the final result represents a pure culture of bacteria.
Step-by-step explanation:
When an agar plate is streaked correctly, the final result represents a pure culture of bacteria. The streak plate method dilutes individual cells by spreading them over the surface of an agar plate, resulting in colonies. Each colony represents the descendants of a single bacterial cell, thus achieving a pure culture with only one type of bacteria.
