Cell Basics
What are the two main types of cells?
Prokaryotic cells and Eukaryotic cells.
What two domains contain prokaryotic cells?
Bacteria and Archaea.
What organisms have eukaryotic cells?
Animals, plants, fungi, and protists.
What organelle is known as the powerhouse of the cell?
Mitochondria.
What is the basic unit of life?
Cell.
Are prokaryotic cells single-celled or multicellular?
Single-celled organisms.
Give three examples of organisms with eukaryotic cells.
Animals, plants, and fungi.
What organelle is responsible for protein synthesis?
Ribosomes.
What is the main difference between prokaryotic and eukaryotic cells?
Prokaryotic cells do not have a true nucleus, while eukaryotic cells have a true nucleus.
Where is the DNA found in a prokaryotic cell?
In the nucleoid region.
What domain includes eukaryotic organisms?
Eukarya.
What organelle controls the activities of the cell and contains DNA?
Nucleus.
Why are cells important to living organisms?
Because cells perform different functions needed for an organism to survive.
Why do prokaryotic cells not have a true nucleus?
Because their DNA is not enclosed by a nuclear membrane.
Why are eukaryotic cells considered more complex?
Because they have membrane-bound organelles and a true nucleus.
What organelle is known as the "suicidal bag" because it contains digestive enzymes?
Lysosome.
What is the main difference between prokaryotic and eukaryotic cells?
Prokaryotic cells do not have a true nucleus, while eukaryotic cells have a true nucleus and membrane-bound organelles.
What process do prokaryotic cells use to reproduce?
Binary fission.
What important structure is present in eukaryotic cells but absent in prokaryotic cells?
True nucleus.
What organelle modifies, packages, and transports proteins and other materials inside the cell?
Golgi apparatus.
