Virus, Bacteria, Fungi - Practice Flashcard

Front

What is a virus?

Back

A virus is a tiny infectious agent that can only multiply inside the living cells of a host organism. They are not considered living organisms because they cannot reproduce on their own.

Front

What is bacteria?

Back

Bacteria are single-celled organisms that can live in various environments. They can reproduce quickly by dividing and do not require a host to multiply.

Front

What is fungi?

Back

Fungi are a group of organisms that include yeasts and molds. They can be single-celled or multicellular and play important roles in decomposition and nutrient cycling.

Viruses can only reproduce by infecting a host cell and using the host's cellular machinery to make copies of themselves.

Front

What is the main difference between bacteria and viruses?

Back

Bacteria are living organisms that can reproduce on their own, while viruses are not living and can only replicate inside a host.

Front

What are some examples of fungi?

Back

Examples of fungi include yeasts, molds, and mushrooms.

Front

How do bacteria reproduce?

Back

Bacteria reproduce asexually by a process called binary fission, where one cell divides into two identical cells.

Front

Can fungi be harmful?

Back

Yes, some fungi can cause infections in humans, animals, and plants, while others are beneficial.

Front

What role do bacteria play in the environment?

Back

Bacteria play essential roles in nutrient cycling, decomposition, and can also be involved in processes like nitrogen fixation.
