Question

describe how environmental pressures might have contributed to differences in bacteria and archaea

Answer 1

Both archaea and bacteria are single celled microbs and they are found in different environment.Archaea are commonly found in salt brine,hot spring and ocean depth.But in the case of bacteria that are found in everywhere like soil,water,food items,detritous matter, organisms etc.Every organism including micro organisms will exhibit several adapatations according to their habitat for survival.So both archaea and bacteria have different adpations according to their living environmental conditions.Both have similarity in their morphology but have difference in anatomy,reproduction, and behaviour etc.They are living in different environment and hence are catagorized as different groups.so we can conclude that environmental pressure might have contributed difference in bacteria and archaea.
