NEET BIOLOGY

Detailed explanation-1: -A bacterial colony is what you call a group of bacteria derived from the same mother cell. This means that a single mother cell reproduces to make a group of genetically identical cells, and this group of cells form a mass, which is known as a bacterial colony.

Detailed explanation-2: -A single bacterial cell is invisible to the naked eye. As that single cell grows and divides into new cells, however, it forms a visible pile of bacteria. In microbiology, we call this pile of bacteria a colony.

Detailed explanation-3: -Although a population of bacteria may be genetically identical, individual bacteria within that population can act in radically different ways. As these bacterial cells divide, chemotaxis machinery (bright blue and red) localize in one daughter cell. This phenomenon is crucial in the bacteria’s struggle for survival.

Detailed explanation-4: -Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall.

Detailed explanation-5: -A colony is defined as a visible mass of microorganisms all originating from a single mother cell, therefore a colony constitutes a clone of bacteria all genetically alike.
