B
Prokaryotes are typically larger than eukaryotic cells.
C
Prokaryotes have multiple linear chromosomes.
D
Prokaryotes lack a membrane-bound nucleus.
Verified step by step guidance1
Understand the basic structure of prokaryotic cells: Prokaryotes are unicellular organisms that lack a membrane-bound nucleus and other membrane-bound organelles.
Compare prokaryotic and eukaryotic cells: Eukaryotic cells have a defined nucleus and various organelles enclosed by membranes, whereas prokaryotic cells do not.
Examine the size difference: Prokaryotic cells are generally smaller than eukaryotic cells, which allows them to have a higher surface area to volume ratio.
Analyze the chromosome structure: Prokaryotes typically have a single circular chromosome, unlike eukaryotes which have multiple linear chromosomes.
Identify the correct statement: Based on the characteristics of prokaryotes, the true statement is that prokaryotes lack a membrane-bound nucleus.
