What is the main difference between prokaryotes and eukaryotes?
Prokaryotes have a nucleus, while eukaryotes do not.
Prokaryotes do not have a nucleus or membrane-bound organelles, while eukaryotes do.
Prokaryotes are larger than eukaryotes.
Eukaryotes reproduce asexually, while prokaryotes reproduce sexually.
What are archaea?
A group of single-celled microorganisms that are prokaryotes, meaning they do not have a nucleus or other membrane-bound organelles.
A type of multicellular organism that has a complex cellular structure with a nucleus.
A category of viruses that infect bacteria and other microorganisms.
A group of eukaryotic organisms that are primarily found in extreme environments.
What is the role of bacteria in the environment?
Bacteria are primarily responsible for photosynthesis.
Bacteria play essential roles in nutrient cycling, decomposition, and some are involved in nitrogen fixation.
Bacteria are harmful organisms that cause diseases only.
Bacteria are only found in soil and have no significant role in the environment.
What is the primary method of reproduction in bacteria?
A) Budding
B) Binary fission
C) Fragmentation
D) Sexual reproduction
Do archaea belong to the prokaryotic or eukaryotic group?
Prokaryotes
Eukaryotes
Multicellular organisms
Viruses
What is a shared trait between archaea and bacteria?
Both are unicellular and prokaryotic organisms.
Both are multicellular and eukaryotic organisms.
Both can perform photosynthesis.
Both have a nucleus in their cells.
What is a pathogen?
A microorganism that can cause disease
A type of virus that always causes illness
A harmless bacteria found in the human body
A type of medication used to treat infections
What are bacteria?
Single-celled microorganisms that are also prokaryotes, found in various environments.
Multicellular organisms that can photosynthesize.
Complex eukaryotic cells that form tissues.
Viruses that can only reproduce inside a host cell.
Why is the domain Archaea significant?
They are known for their ability to survive in extreme environments, such as hot springs and salt lakes.
They are the only organisms that can perform photosynthesis.
They are the primary producers in most ecosystems.
They are the most abundant organisms on Earth.

What is a typical method for classifying bacteria?
By their color
By their shape, such as cocci (spherical), bacilli (rod-shaped), and spirilla (spiral-shaped)
By their size
By their habitat
Can you name another domain of life apart from Archaea? It is also unicellular.
Bacteria
Fungi
Plants
Animals
What components make up the structure of a bacterial cell?
Cell wall, cell membrane, cytoplasm, and genetic material (DNA) that is free-floating
Nucleus, mitochondria, ribosomes, and chloroplasts
Cell membrane, cytoplasm, endoplasmic reticulum, and lysosomes
Cell wall, cytoplasm, vacuoles, and RNA
Where is the DNA (genetic material) located in a prokaryotic cell?
Nucleus
