Archaea are single-celled microorganisms that are distinct from bacteria and eukaryotes. They are known for their resilience in extreme environments, but unlike plants and some protists, archaea do not have chloroplasts.
Chloroplasts are organelles found primarily in the cells of green plants and some algae, which are responsible for photosynthesis. These organelles have their own DNA and are thought to have originated from a symbiotic relationship with ancient bacteria.
Most archaea do not perform photosynthesis, and those that obtain energy through light usually do so with different structures, such as bacteriorhodopsin, rather than chloroplasts. In summary, while archaea are fascinating microorganisms with unique adaptations, they do not possess chloroplasts.
