Question

Theory ofprogressive sterilization sporogenous tissue for bryophytes was given by

Answer 1

According to this theory, the most primitive and simplest sporophyte is found in the genus Riccia which has evolved from an ancestral sporophyte that consisted of a mass of sporogenous tissue with all cells being fertile.

Answer 2

The sterilization of sporogenous tissue is very complex and this is a bryophytes process.

According to Bower, sporophytes have been evolved from the simpler ones and sporogenous tissues can be formed by the progressive sterilization.

The evolution may be traced from the simplest sporophyte found in Riccia (Hepaticopsida) to the more complex sporophyte found in Funaria (Bryosida).
