A) diploid spores
B) protonema
C) oospores
D) antherozoids
Correct Answer: B
Solution :
The plant body is gametophyte in moss, which develops from the germination of the meiospores. The moss spores (meiospores) on germination give rise to a branched filamentous structure called protonema. It is heterotrichous, ie, it is differentiated into prostrate creeping branched system, which is multicellular and has obliquely oriented septa. The prostrate branched system gives two types of branches. Those growing upward are green, have numerous chloroplasts in their cells and possess transverse septa, and those growing downwards and penetrating into the substratum function as organs of absorption and anchorage.
