Q

Most prokaryotic cells divide by the process of _____

A

binary fission

17
Q

Binary fission undergo 4 phases: ____, ____, ____, ____

A

Lag phase, Log phase, Stationary phase, death phase

18
Q

List three differences of characteristic of prokaryotic cells and eukaryotic cells.

A

Prokaryotes lack a true nucleus, but eukaryotes has a nucleus. Prokaryotes has no membrane-bound organelles while eukaryotes has membrane-bound organelles like ER, lysosome. Prokaryotes undergo binary fission when eukaryotes undergo mitosis.
