Question

Auxospores are formed in the life cycle of diatoms these structure are ________________.

• A. Vegetuative cells with ploidy level N
• B. Asexual spores with ploidy level N
• C. Statosspores with 2N ploidy Level
• D. Sexual spores with ploidy level $2N$

Answer 1

The correct option is A Vegetuative cells with ploidy level N

Auxospores are formed by diatoms at an important stage of their life cycle. They are specialized cells which help the diatoms in regaining their normal size. After cell division in diatoms, each daughter cell inherits one of the two valves and hence results in reduction of size of the diatom, to retain the size diatoms produce auxospores and hence they are vegetative.

So, the correct option is, 'Vegetuative cells with ploidy level N'.
