- Cyanobacterial Classification (Rippka et al., 1979 / Bergey's Manual):
- Sectional Characteristics and Representative Genera:
- Baeocytes $\rightarrow$ (IV) Pleurocapsa: Section II (Pleurocapsalean cyanobacteria) reproduce by multiple fission of mother cells into small spherical disseminules called baeocytes.
- Filamentous, binary fission in single plane $\rightarrow$ (V) Lyngbya: Section III (Oscillatoriales) form unbranched, non-heterocystous filaments dividing in one plane.
- Filamentous, produce heterocysts $\rightarrow$ (I) Nodularia: Section IV (Nostocales) produce specialized dinitrogen-fixing heterocysts and unbranched filaments.
- Cells divide in multiple planes, form branching filaments $\rightarrow$ (III) Fischerella: Section V (Stigonematales) divide in multiple planes to form true-branching, multiseriate filaments.
- Unicellular or cellular aggregates $\rightarrow$ (II) Gloeothece: Section I (Chroococcales) are unicellular or colonial aggregates enclosed in mucilaginous sheaths.
- Correct Choice: Option 2 maps (A)-(IV), (B)-(V), (C)-(I), (D)-(III), (E)-(II).
Correct option: (2) (A) - (IV), (B) - (V), (C) - (), (B) - (HI, (E) - )
