Cytokinesis
What cell division do plant cells undergo?
Cytokinesis
What cell division do yeast cells undergo?
Budding
What cell division do bacterium cells undergo?
Binary fission
Which organisms have a nucleus present in there cells?
Animal, plant and yeast cells
Which organism lacks a nucleus in its cells?
Bacterium
What material is present in an animal cell wall?
None, animal cells lack a cell wall
What material is present in a plant cell wall?
Cellulose
What material is present in a yeast cell wall?
Chitin
What material is present in a bacterium cell wall?
disaccharides and amino acids form a bacterium cell wall (peptidoglycan/murein is its more common name)
Are ribosomes present in animal cells?
Yes
Are ribosomes present in plant cells?
Yes
Are ribosomes present in yeast cells?
No
Are ribosomes present in bacterium cells?
No
Do eukaryotic cells have a nucleus?
Yes
Do prokaryotic cells have a nucleus?
No
Do eukaryotic cells have DNA?
Linear in nucleus when de-condensed for replication (multiple layer chromosomes)
Do prokaryotic cells have DNA?
Circular and loose in cytoplasm (or an area called the nucleoid), (a single chromosome)
Do eukaryotic cells have a cell wall?
Some have made of cellulose (in plants) or chitin (in yeast)
Do prokaryotic cells have a cell wall?
Mainly a peptidoglycan cell wall (made of murein)
Do eukaryotic cells have membrane-bound organelles?
Yes many
Do prokaryotic cells have membrane organelles?
No, they lack them (no nucleus)
Do eukaryotic cells have ribosomes?
Yes, large (80s ribosomes)
Do prokaryotic cells have ribosomes?
Yes, smaller (70s ribosomes)
