Explanation:

To determine the answer, we analyze each option:

• Option A: Plants do have chloroplasts for photosynthesis, so this is a defining characteristic.
• Option B: Prokaryotic cells lack a nucleus and membrane - bound organelles. Plant cells have a nucleus and membrane - bound organelles (like chloroplasts, mitochondria), so plants are eukaryotic, not prokaryotic. Thus, this is not a defining characteristic of plants.
• Option C: Plants are eukaryotic (have a true nucleus and membrane - bound organelles), so this is a defining characteristic.
• Option D: Plant cells have cell walls (composed mainly of cellulose), so this is a defining characteristic.

Answer:

B. Plants are prokaryotic
