258246 The main difference in Gram (+)ve and Gram $(-)$ ve bacteria resides in their:

258248 Identify combination of incorrect statements related to cyanobacteria
I. Cyanobacteria are referred to as bluegreen algae
II. They perform oxygenic photosynthesis in chloroplasts
III. The red- colour of red-sea is due to the presence of a cyanobacterial species Trichodesmium erythraeum.
IV. All the cyanobacterial species can fix atmospheric $\mathrm{N}_{2}$ in specialised cells called heterocysts.

258250 The following are true about culture media for microbes

258251 Examples of photoautotrophic bacteria which capture light energy and transform it into chemical energy to obtain carbon from atmospheric carbon dioxide are
i. Anabaena
ii. Nitrosomonas
