EVERYDAY SCIENCE

Detailed explanation-1: -Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes. The prokaryotic cell membrane is made up of phospholipids and constitutes the cell’s primary osmotic barrier.

Detailed explanation-2: -Prokaryotic cells are believed to be the oldest cells on Earth. Thus, all bacteria are prokaryotic, but not all prokaryotes are bacteria. The other major group of prokaryotes is the blue green algae (also known as cyanobacteria).

Detailed explanation-3: -Bacteria are the most common prokaryote organisms that we encounter every day, ranging from harmful to beneficial ones. Archaea are prokaryotes that inhabit extreme environments, such as inside of volcanoes; Their ancestor is believed to have given rise to Eukarya, the third domain of life.

Detailed explanation-4: -Bacteria are classified as prokaryotes, along with another group of single-celled organisms, the archaea. Prokaryotes are tiny, but in a very real sense, they dominate the Earth. They live nearly everywhere – on every surface, on land and in water, and even inside of our bodies.

Detailed explanation-5: -The bacteria are the oldest and simplest living organisms, and all of the bacteria are “prokaryotes, ” meaning that they do not have a true membrane-bound nucleus as eukaryotes do.
