Question

Feature of the cyanobacteria which resembles green plant is

• A. Presence of chlorophyll a
• B. Absence of carotenoids
• C. Oxygenic photosynthesis
• D. Presence of phycobilins

Answer 1

The correct option is A Presence of chlorophyll a

Cyanobacteria, although they are truly prokaryotic, cyanobacteria have an elaborate and highly organized system of internal membranes which functions in photosynthesis. Chlorophyll a and several other pigments are embedded in this photosynthetic lamellae. Cyanobacteria were likely part of a process of endosymbiosis by eukaryotic cells, resulting in the chloroplast found in the plants and algae.

So the correct answer is ' Oxygenic photosynthesis".
