B) A-1 B-4 C-2 D-5
C) A-5 B-1 C-2 D-3
D) A-2 B-4 C-1 D-3
Correct Answer: D
Solution :
The ovule of Cycas contains a three layered unitegmic integument. The outer most, fleshy layer of this integument is call sarcotesta. Because integument is a diploid structure, so, the sarcotesta is also a diploid structure. Aposporous gametophores of Funaria is developed directly from gametophytic tissue (without union of gametes). So, it is a haploid structure. Azygospore in Rhizopus is formed when a gametangium somehow becomes unable to fuse with their respective gametangium. This gametangium now forms two-three layers around us and called a zygospore. Hypostomium of Pteris is a diploid structure.You need to login to perform this action.
