Question

some students used information they gathered from lab investigations to prepare a table. they entered the table in their lab notes. which of these correctly identifies the two cells described in the table? a cell 1 is eukaryotic and cell 2 is prokaryotic. b cell 1 is prokaryotic and cell 2 is eukaryotic. c both cell 1 and cell 2 are prokaryotic. d both cell 1 and cell 2 are eukaryotic.

Explanation:

• Eukaryotic cells are generally larger (often larger than 10 micrometers), have membrane - bound organelles (including a membrane - bound nucleus), and linear DNA.
• Prokaryotic cells are smaller (usually smaller than 5 micrometers), lack membrane - bound organelles (no true nucleus), and have circular DNA.
• Cell 1: Larger than 10 micrometers, has membrane - bound organelles, has a membrane - bound nucleus, has linear DNA → matches eukaryotic cell characteristics.
• Cell 2: Smaller than 5 micrometers, does not have a nucleus, does not have membrane - bound organelles, has circular DNA → matches prokaryotic cell characteristics.

Answer:

A. Cell 1 is eukaryotic and Cell 2 is prokaryotic.
