• A. Petri Plate
• B. Petri Dish
• C. Culture Vessel
• D. Culture Plate

Answer: (A)

The item is called a Petri dish. It’s a small, shallow, circular container with a lid that holds a nutrient medium (often agar) so microorganisms can grow in a controlled, visible way. The dish’s flat shape makes it easy to observe colonies, and the lid helps protect the culture from contamination while still allowing air exchange. While you might hear people say “Petri plate” in casual speech, the standard term used in microbiology is Petri dish. A culture vessel is any container used for growing organisms, and “culture plate” isn’t the conventional name for this specific dish.
