WebDec 28, 2024 · sirichai_raksue/Getty Images. The fern "life cycle" refers to sexual reproduction. However, ferns use asexual methods to reproduce, too. In apogamy, a sporophyte grows into a gametophyte without fertilization occurring. Ferns use this method of reproduction when conditions are too dry to permit fertilization. WebHairy cap moss is a photosynthetic autotroph, it makes food (carbohydrate) through the process of photosynthesis and then uses this carbohydrate both as a material to make biomolecules and also to provide energy for metabolic activities. For the gametophyte, this is true throughout its existence.

WebEventually, gametophytes create gametes that combine to produce a diploid zygote and grows into the sporophyte. Diploid sporophytes consist of two copies of every chromosome, hence it is able to support meiosis to produce haploid spores that grow into gametophytes, and brings the alternation of generations. WebOne generation is known as the gametophyte and the second is the sporophyte. The gametophyte produces haploid spores with only have the genetic material of gametophyte cells. The sporophyte is grown when released spores germinate in a new environment and begin dividing. For bryophytes, the gametophyte is the most obvious generation.
