View the following short animation from the MyMicrobiologyPlace website accessible through the link on your student website: Microbiology Animations With Quizzes: Bacterial Growth: Overview. Which of the following is true about how bacterial cells divide? They divide into 2 daughter cells. They divide by binary division.
They divide sexually.
They divide by mitosis.
They divide by meiosis.
They divide asexually.
They divide into two daughter cells.
View the following short animation from the MyMicrobiologyPlace website: Microbiology Animations With Quizzes: Bacterial Growth Curve. Which of the following is true about bacterial growth? Growth is an increase in the number of cells over time. Growth is an increase in the size of cells over time.
Growth is an increase in the number of cells over time.
Growth consists of lag, log, stationary, and death phases.
Growth only occurs during the log phase.
Describe what happens to cells in each phase of bacterial growth: lag phase, log phase, stationary phase, and . phase.
LAG phase: bacterial cells are busy replicating various proteins and DNA in preparation for the next phase. LOG phase: The bacterial colony increases dramatically, It happens quickly. STATIONARY phase: This part is the slow growth,the rate of cell death begins to match the rate of cell division. DEATH phase: When conditions become bad of course the fourth part of the phase they eventually die.
View the following short animation from the MyMicrobiologyPlace website: Microbiology Animations With Quizzes: Binary Fission. What are the stages of binary fission? The parent cell maximizes, cell duplicates its chromosome, exact copies are made of genetic material inside parent cell, wo molecules of DNA are attached to the cell’s plasma membrane, the cell then grows, it then increses the distance between the two duplicating chromosomes that are attached to the plasma...
