Hints

Consider the given two statements:

I: Gas vacuoles, found in cyanobacteria, are membrane-bound, spindle-shaped vesicles that provides buoyancy to these cells.
II: Positive buoyancy is needed to keep the cells in the upper reaches of the water column, so that they can continue to perform photosynthesis.

1. Both I and II are correct and II explains I
2. Both I and are correct but II does not explain I
3. I is correct and II is incorrect
4. Both I and II are incorrect

Hints

A genophore is the DNA of a prokaryote. Though it is commonly referred to as a prokaryotic chromosome, the term “chromosome” is misleading, because:

1. the genophore lacks chromatin
2. the genophore is circular rather than linear
3. the genophore replicates without telomeres
4. the genophore is not enclosed in a nuclear membrane
