Microorganisms can be seen clearly without a microscope.

Bacteria can reproduce through binary fission and conjugation.

Fungi are always unicellular organisms.

Protozoa reproduce only through binary fission.

Algae are autotrophic organisms that perform photosynthesis.

Viruses can reproduce on their own without a host.

Normal flora in the human body help in digestion and vitamin production.

All microorganisms are harmful and cause diseases.

Bacteria exist in different shapes like cocci, bacilli, spirals, and commas.

Fungi reproduce only through spores.

Protozoa are always multicellular organisms.

Algae can be found in both unicellular and multicellular forms.

Viruses do not require food because they are not living organisms outside a host.

Normal flora can prevent harmful pathogens from colonizing the body.

Moisture is not required for microbial growth.

The pH level of the environment affects microbial growth.

Algae do not require light for photosynthesis.

Microorganisms grow best at temperatures around 5°C to 10°C.

Some bacteria can perform photosynthesis and produce their own food.

Antibiotics can disrupt the balance of normal flora in the body.
