Summary Introduction
Introduction:
Cyanobacteria acquire their energy by means of photosynthesis. It is the only photosynthetic prokaryote that have the capability to yield oxygen. The name “cyanobacteria” was derived from the color (cyan) of the bacteria. It is commonly present in fresh water lakes, oceans, damp soil, streams, and so on.

Which of the following is NOT true about bacterial endospores?
A. They are produced by bacteria of the genus Bacillus and Clostridium
B. They are “resting cells” for survival during adverse environmental conditions
C. Resistant to desiccation (drying), heat, and chemicals
D. Formed by walling off one end of the bacterial cell and surrounding it with a thick spore coat
E. They represent a type of reproduction because their formation results in an increase in the number of bacterial cells
