Question

5 which characteristic is shared by all prokaryotic and eukaryotic organisms? a contain genetic material b contain membrane - bound organelles c use the same method of reproduction d use the same method of obtaining nutrition

Explanation:

• Option A: All prokaryotic (e.g., bacteria) and eukaryotic (e.g., animals, plants) organisms contain genetic material. Prokaryotes have their genetic material (usually a circular DNA molecule) in the cytoplasm (nucleoid region), while eukaryotes have their genetic material (linear DNA) enclosed in a nucleus.
• Option B: Prokaryotes lack membrane - bound organelles. Eukaryotes have various membrane - bound organelles like mitochondria, endoplasmic reticulum, etc.
• Option C: Prokaryotes mainly reproduce asexually (e.g., binary fission), while eukaryotes can reproduce asexually (e.g., mitosis in some single - celled eukaryotes) or sexually (in most multicellular eukaryotes).
• Option D: Prokaryotes can be autotrophic (e.g., cyanobacteria) or heterotrophic (e.g., E. coli). Eukaryotes also have autotrophs (plants - photosynthetic) and heterotrophs (animals - ingestive, fungi - absorptive). The methods of obtaining nutrition are diverse.

Answer:

A. contain genetic material
