A) ventral canal cell
B) foot
C) calyptra
D) protonema
Correct Answer: D
Solution :
Under favourable condition of light, water and temperature the spores of Funaria germinates One or more germ tube are formed during Germination. A cross wall forms at the point of emergence of each germ tube. The germ tube grows in length and divides by septa to form a filament of green cells. The branched green alga like filament is called primary protonema. The sporogonium in both Funaria and Marchantia is differentiated into foot, seta and capsule. The venter wall in bryophytes enlarges with the developing embryo to form a protective multicellular envelope the calyptra. The venter canal cell is formed in the archegonia ofMarc/ianda and Funaria both.
