Microbiology Study Guide
Explanation / Answer
37. b) Bergey's Manual.
Bergey's Manual of systemic bacteriology is a reference text that serves as a mode to classify prokaryotes on the ground of their structural and functional forms by organizing them into specific familial orders.
38. c) Halophiles.
The dead sea is a hypersaline terminal desert lake, therefore, it is normal for the halophilic microorganism such as algae, fungi, archaea, and bacteria to flourish there in such extreme condition of salinity because their cellular machinery conform to the high salt condition by possessing charged amino acid on its surface thereby supporting the retention of water molecules around these components.
39. e) Hyperthermophiles.
Hyperthermophiles are microbes that can thrive in extreme temperature ranges that is above 800 C and that's the reason they might be found in hot springs. In addition, hyperthermophiles are also found to withstand extreme acidity and radiation levels. A large amount of saturated fatty acids present in their cell membrane prevents their shape from distorting into other forms.
40. c) Bacterial cells that are arranged in a group of 8 cells as a cube is referred sarcinae. Sarcinae result when spherical shaped bacteria that is coccus are organized as a cube like pattern from 8 cells or more. Example- Sarcina ureae.
41. d) When bacterial cells are arranged in a parallel arrangement, side by side they are referred as a palisade. Bacilli that is rod-shaped bacteria inclines following cell division leading to such pattern of the palisade. Example- Corynebacterium diphtheria.
42. a) Bacterial cells arranged in chains are strepto. Example- Streptobacillus moniliformis.
43. e) Endospores are tough, dormant, non reproductive structure that contribute in protection in unfavourable conditions.
