Question

Find odd one w.r.t. ploidy level in bryophytes

• A. NCC
• B. VCC
• C. Spore
• D. Foot

Answer 1

The correct option is C Spore

NCC or neck canal cells and VCC or ventral canal cells of bryophytes are present in the archegonium of the gametophytic plant body (n). Thus, the ploidy level of NCC and VCC is haploid (n). The foot is found in the mature sporophyte (2n); hence, the ploidy level of the foot is diploid (2n).

The spores (n) are developed by the meiotic division of the spore mother cells (2n); thus, the ploidy level of spore is haploid (n).

So, the correct answer is option C, spore.
