EVERYDAY SCIENCE

Detailed explanation-1: -False. Hint: Bacteria are microscopic single-celled organisms. They are everywhere in the environment.

Detailed explanation-2: -Bacteria are single celled microbes that lack a nucleus. Archaea are like bacteria, but they have different structures and properties. This gives them the ability to live in extreme environmental conditions. Protozoa are unicellular microorganisms that have nuclei.

Detailed explanation-3: -Bacteria are not multicellular. They are unicellular organisms, possessing only one cell. All functions required to sustain life like growth, metabolism, reproduction, etc are carried out by a single cell in bacteria.

Detailed explanation-4: -Bacteria are small single-celled organisms. Bacteria are found almost everywhere on Earth and are vital to the planet’s ecosystems. Some species can live under extreme conditions of temperature and pressure. The human body is full of bacteria, and in fact is estimated to contain more bacterial cells than human cells.

Detailed explanation-5: -Bacteria are unicellular microorganisms and thus are generally not organized into tissues. Each bacterium grows and divides independently of any other bacterium, although aggregates of bacteria, sometimes containing members of different species, are frequently found.
