Chemosynthetic bacteria

Vedclass · Answer

(B, C, D) Chromatophores are specialized membrane-bound vesicles found in some photosynthetic prokaryotes (like cyanobacteria) that contain pigments for photosynthesis.They are absent in eukaryotic organisms such as $Pteridophyta$,$Gymnosperms$,and $Angiosperms$ because these organisms possess specialized membrane-bound organelles called chloroplasts for photosynthesis.Since the question asks where they are absent,and options $B$,$C$,and $D$ are all eukaryotes,this question is technically flawed as it has multiple correct answers. However,in the context of typical biology curriculum,chromatophores are specifically associated with prokaryotic cells. If the question implies which of these groups lacks them entirely,all three $(B, C, D)$ are correct.
