Question 8

It is possible to take the mature frond of many ferns and rub the brown growths on the lower surface over a wet plug of peat moss.Soon small heart-shaped green structures grow on the nutritious peat moss plugs.What has happened?

Accepted Answer

A) You have broken off male and female structures from the bottom of the fern frond,and they united on the wet plug to form the sporophyte generation called a prothallus. 
B) You have broken the sori on the bottom of the fern frond,and spores fell on the plug to germinate and form the gametophyte called a prothallus. 
C) You have broken the sori on the bottom of the fern frond,and spores fell on the plug to germinate and form rhizomes that develop an indusium. 
D) You have broken the indusium on the bottom of the fern frond,and zygotes germinated on the plug to form the sporophyte made of an archegonium and an antheridium. 
E) You have broken the sori on the bottom of the fern frond,and zygotes germinated on the plug to form the fiddleheads that will develop into more fronds.
