The given diagram represents Nostoc, a filamentous cyanobacterium. What are the primary functions of the structures labeled as 'Heterocyst' and 'Mucilaginous sheath'?

Heterocyst fixes atmospheric nitrogen; Mucilaginous sheath surrounds and protects the bacterial colony
Heterocyst is for vegetative propagation; Mucilaginous sheath is for light absorption
Heterocyst stores excess carbohydrates; Mucilaginous sheath aids in active movement
Heterocyst functions in sporulation; Mucilaginous sheath absorbs inorganic salts

Correct answer · Option 1

Heterocyst fixes atmospheric nitrogen; Mucilaginous sheath surrounds and protects the bacterial colony

Explanation

In *Nostoc* (Figure 2.2), heterocysts are specialized cells for atmospheric nitrogen fixation, and the mucilaginous sheath surrounds the colonial filaments providing protection.
