Regarding microbiology, analyze the following statements: I- The bacterial cell wall is responsible for the shape and protection of the cell, and its composition varies between different bacterial species. II- The bacterial cell membrane is responsible for the transport of substances into and out of the cell, and its composition is similar to that of eukaryotic cells. III- The bacterial chromosome is circular and is not associated with histones, and the genetic material can also be found in plasmids. IV- The bacterial cell can reproduce by binary fission, which is a simple and less complex process than mitosis. V- The bacterial growth kinetics in the culture medium presents a uniform growth curve, and during the logarithmic phase, cellular growth begins.
A) I, II, III, IV and V are correct. B) I, II, III and IV are correct. C) V is correct only.
A alternativa correta é a letra B) I, II, III e IV estão corretas. A afirmação V está incorreta, pois a curva de crescimento bacteriano não é uniforme, mas sim dividida em quatro fases: fase de latência, fase logarítmica, fase estacionária e fase de morte.
