LIFE SCIENCE

Detailed explanation-1: -Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm.

Detailed explanation-2: -Bacteria are prokaryotic and unicellular organisms. The cell wall of bacteria is made up of peptidoglycan layer, and they lack membrane-bound organelles. The bacterial cell has a simpler organisation of structure. Hence, the given statement is false as bacteria are not eukaryotic organisms.

Detailed explanation-3: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-4: -Bacteria do not have a well-defined nucleus. It lacks cell organelles. It has single circular genetic material in which only one chromosome is present. Thus bacterial cell is considered as a prokaryotic cell.
