Question

In ______, the sporophyte is dependent on the larger gametophyte, whereas in ______, the gametophyte generation is dependent on the larger sporophyte generation.

Answer 1

In Bryophytes, the sporophyte is dependent on the larger gametophyte, whereas, in Angiosperm and Gymnosperms, the gametophyte generation is dependent on the larger sporophyte generation.

Difference between gametophyte and sporophyte.

• The gametophyte is the haploid(n) state in the life cycle whereas the sporophyte is the diploid(2n) state in the life cycle.
• Gametophyte leads to gamete formation whereas sporophyte leads to the formation of spores.
• Spore formation takes place post meiosis whereas gamete formation either occurs directly or through mitosis.
• The meiospore grows to develop into the gametophyte. The zygote grows to produce sporophytes
• The cells in sporophytes have two genomes or possess two sets of chromosomes. The cells of the gametophyte have a single genome or produce one set of chromosomes.
