Términos en este set(24)
Prokaryote definition
Simple, unicellular organisms without a nucleus.
Eukaryote definition
Complex, multicellular organisms with a nucleus.
True or false: Prokaryotes have membrane-bound organelles.
False, because prokaryotes lack membrane-bound organelles.
Difference between prokaryote and eukaryote
Prokaryotes are simpler, no nucleus; eukaryotes are complex, have a nucleus.
Fill in the blank: Prokaryotes often have __________ DNA.
circular
What is an example of a prokaryote?
Bacteria are common prokaryotes.
What is an example of a eukaryote?
Humans, plants, and fungi are eukaryotes.
True or false: Eukaryotic cells are always larger than prokaryotic cells.
True, because eukaryotic cells typically have more complex structures.
Prokaryotic cell wall composition
Made of peptidoglycan in bacteria.
Eukaryotic cell examples
Plants, animals, fungi, and protists.
What is the main function of the nucleus?
Contains genetic material and controls cell activities.
Difference in reproduction: prokaryotes vs eukaryotes
Prokaryotes reproduce asexually (binary fission); eukaryotes can reproduce sexually or asexually.
Fill in the blank: Prokaryotic cells lack a __________.
true nucleus
Which organelle is found in eukaryotes but not prokaryotes?
Mitochondria
Function of ribosomes in both cell types
Protein synthesis.
True or false: Prokaryotes can have plasmids.
True, plasmids are extra-chromosomal DNA.
Comparison: Size of prokaryotic vs eukaryotic cells
Prokaryotic cells are typically 0.1 to 5.0 µm; eukaryotic cells are 10 to 100 µm.
What structure is common to both prokaryotes and eukaryotes?
Cell membrane
Fill in the blank: Eukaryotic cells can have __________ organelles.
membrane-bound
True or false: All eukaryotic cells have a cell wall.
False, animal cells do not have a cell wall.
Prokaryote reproduction method
Binary fission, a simple division process.
Eukaryotic cell division process
Mitosis or meiosis for cell division.
Prokaryotes typically lack which structure?
Nucleus and membrane-bound organelles.
Function of the cytoplasm
Site for cellular processes in both prokaryotes and eukaryotes.
