Solution:

Cyanobacteria are autotrophic in nature. Photosynthetic pigments include chlorophyll a, carotenoids and phycobilins. Photosynthetic thylakoids occur freely in the outer part of protoplast called chromoplasm. Cyanobacteria are prokaryotic due to lack of membrane bound cell organelles (chloroplast, etc.) and distinct nucleus.
