Introduction:
Bacteria are prokaryotic and unicellular organisms that either present in a cluster of cells or in isolated forms. The cell wall of bacteria is made up of peptidoglycan layer and they lack membrane-bound organelles. Bacteria can grow either in presence of oxygen (aerobes) or in the absence of oxygen (anaerobes).

Answer to Problem 1MC
Correct answer:
An aerobic bacterium can be grown in a Petri plate in laboratory conditions.
Therefore, option (b) is correct.
Option (b) is given as “an aerobic bacteria”.
Explanation of Solution
Justify the reason for the correct statement:
Bacterial cells can be cultured in the laboratory by giving them a growth media consisting required amount of nutrients and oxygen by the bacterial cell. A bacterial colony can be grown on agar medium or Petri plate. An aerobic bacterium can grow in presence of oxygen on a Petri plate containing growth medium.
Hence, option (b) is correct.
Justify the reasons for the incorrect statements:
Option (a) is given as “an anaerobic bacterium”.
Anaerobic bacterium needs maintained conditions to grow. The anaerobic bacteria grow only in the absence of oxygen and in an inoculated Petri dish that contains a seal to prevent entry of oxygen. They cannot grow in presence of oxygen in a Petri plate. Hence, it is a wrong answer.
Option (c) is given as “viruses on an agar surface”.
Viruses can grow on special growth media like bacterial cells or on tissues. They cannot be grown on agar in Petri plate. Hence, it is a wrong answer.
Option (d) is given as “all of the above”.
The aerobic bacterium can be grown on Petri plate but other options: anaerobic bacterium and viruses are incorrect as they cannot be grown on Petri plate. Hence, it is a wrong answer.
Hence, options (a), (c), and (d) are incorrect.
The aerobic bacterium which needs oxygen to grow can be cultured on growth medium in Petri plate.
