Which tool is used to culture microorganisms in a laboratory setting?

• A. Petri Plate
• B. Microscope
• C. Pipette
• D. Centrifuge

Answer: (A)

To culture microorganisms, you need a surface with nutrients and a controlled environment where they can multiply and form colonies. A Petri plate provides that: a shallow dish with a growth medium like agar, which gives microbes the food and space they need to grow in visible colonies when incubated under the right conditions. The microscope is for observing microorganisms, not growing them. A pipette helps transfer liquids, but it doesn’t supply a growth medium. A centrifuge spins samples to separate components, not to promote growth. So the tool designed to grow and isolate microbial colonies in a lab setting is the Petri plate.
