Bacteria do not have chloroplast but some bacteria are photoautotrophic in nature and perform photosynthesis. Which part of the bacterial cell performs this?

Bacterial cell do not have chloroplast but yet some photoautotrophic bacteria perform photosynthesis due to the presence of chlorophyll in cooperated in the membrane. Embedded in the cell membrane are reaction centers which specifically absorb light energy. This reaction centre exist in forms of sacs-tubes or sheets depending on the amount of surface area needed.

  • The Cyanobacteria are the largest and most diverse group of photosynthetic bacteria previously known as blue-green algae.
  • These are true prokaryotes having no chloroplast but still perform photosynthesis.
  • The reason for this is that they have chlorophylls which are dispersed in cytoplasm(not packed in chloroplast like photosynthetic eukaryotes)
