In photosynthetic prokaryotic bacteria, such as cyanobacteria, chlorophyll is associated with membranous vesicles. These membranous vesicles, also known as thylakoids, are where the process of photosynthesis takes place.

Option 1: Plastids are organelles found in eukaryotic cells, such as plant cells, that are involved in processes like photosynthesis. They are not found in prokaryotic bacteria, so chlorophyll is not associated with plastids in these bacteria.

Option 2: This is the correct answer. Chlorophyll in photosynthetic prokaryotic bacteria is indeed associated with membranous vesicles called thylakoids. Thylakoids contain the pigments needed for capturing light energy during photosynthesis.

Option 3: Nudeoids do not exist. There is a typo in this option.

Option 4: Chromosomes carry genetic information and are involved in cell division and reproduction. They do not play a direct role in photosynthesis, so chlorophyll is not associated with chromosomes in photosynthetic prokaryotic bacteria.

Overall, option 2 is the correct answer as chlorophyll in photosynthetic prokaryotic bacteria is indeed
