When bacterial cells are placed in a nutrient rich medium containing all the nutrients required for the growth of the bacteria, the bacteria exhibit a typical growth curve. Initially on transferring into the medium, the population of bacteria remain the same for a short period called the lag phase. They increase in size and prepare the cells for cell division exhibiting active metabolism. The bacteria then enters the log phase, showing an increase in the number of bacteria in a logarithmic fashion by binary fission. Thus, the lab technician can observe the process of cell division by binary fission under the microscope. The bacterial cells then tend to remain constant in the stationary phase and finally decline in number due to the death of the cells.
A lab technician places a colony of bacterial cells in a nutrient-rich growth medium. the most likely event the technician will observe with a microscope is bacterial movement and bipartition reproduction.
What is the bipartition process?
This type of reproduction, also called bipartition, cissiparity or fission, occurs in different organisms and is common in protozoa and bacteria. The process of binary division is based on dividing the organism in half, giving rise to another identical organism, except when mutations arise.
With this information, we can conclude that a laboratory technician places a colony of bacterial cells in a nutrient-rich growth medium. the most likely event the technician will observe with a microscope is bacterial movement and bipartition reproduction.
