Exploring the World of Cell Culture in Petri Dishes

What is a common container used for growing a culture of living cells?

A. agar block

B. petri dish

C. graduated cylinder

D. glass slide

Answer:

Petri dish

Explanation:

It is used to culture cells.

Cell culture is a fundamental technique in biological research, allowing scientists to study the behavior of living cells in a controlled environment. One of the most common tools used for cell culture is the petri dish. A petri dish is a shallow, flat, cylindrical container made of glass or plastic that is used to culture cells.

The petri dish provides a sterile environment for cells to grow and allows researchers to observe their growth and behavior under a microscope. It is essential for tasks such as studying cell morphology, growth rates, and interactions between different cell types.

To culture cells in a petri dish, a nutrient-rich agar medium is typically poured into the dish, creating a solid surface for the cells to adhere to and grow. The cells are then introduced to the agar medium and incubated at an appropriate temperature and humidity to promote their growth.

Overall, petri dishes play a crucial role in cell culture techniques and are a staple tool in biological laboratories worldwide. Their versatility and convenience make them an indispensable asset for studying the intricate world of living cells.
