Question

complete the following analogy. blood cell:___________ bacteria:____________ A.eukaryotic cells ,prokaryotic cells B.prokaryotic cells,eukaryotic cells C.rod cell,oval cell D. none of the above

Answer 1

The correct answer A.eukaryotic cells ,prokaryotic cells. This means the blood cells are eukaryotic and the bacteria are prokaryotic cells.

The red blood cell although lacks nucleus still is considered to be eukaryotic in nature. The stem cell from where the red blood cell originates has a nucleus which disappears on maturity to make space available for carrying oxygen and carbon dioxide .

The bacterial cells are prokaryotic in nature. The bacterial cell is also enclosed by a cell membrane and the cellular contents are present in the cytoplasm. The bacteria lack the membrane bound structures as opposed by the eukaryotes. nucleus, mitochondria and chloroplast are some of the organelles lacking in the prokaryotic bacteria.  

Answer 2

The analogy is as follows blood cell: Eukaryotic cell, bacteria: prokaryotic cell

Answer: Option A

Explanation:

The eukaryotic cells are cells that have a well-defined membrane bound organelles and well defined ''nucleus'', a prokaryotic cell does not have any of these characteristics.

Moreover a prokaryotic cell mostly is present in microorganisms whereas a eukaryotic cell is mostly present in macro and multicellular organisms. But there are exceptions to it which contain a single celled ''eukaryote''. Blood cell is a eukaryotic cell whereas a bacteria is a single celled ''prokaryote''.
