In Funaria (moss) spore germinates to produce
Open in App
Solution
The correct option is A Protonema
The spores of Funaria are 12 - 20 microns in diameter, and represent the first cell of the gametophytic generation. The spore wall consists of two layers, the outer smooth and brown coloured exosporium, and the inner colourless endosporium. The cytoplasm of spore is rich in oil globules and chloroplasts. The spore germinates under favourble conditions. The exospore is ruptured and the endospore produces a papilla. It soon forms a long filamentous protonema. The protonema shows apical growth and forms two types of branches, the chloronemal branches and the rhizoidal branches.
