Life cycle of a fern diagram

Ferns are seedless vascular plants.Most of them are terrestrial where as some are epiphytes, xerophytes or hydrophytes. Some of the members are Salvinia, Azolla, Adiantum etc..

Sporophytic phase may produce spores on ... Nostoc is a genus of cyanobacteria (blue-green algae). They are found mainly in freshwater as free-living colonies or attached to rocks, tree trunks or at the bottom of lakes. They are also found in symbiotic association with plants such as water fern and Anthoceros. The life cycle of a plant describes the different stages of the plant from the beginning of its life until the end, which is from seed to mature plant. However, not all plants produce seed.

The arrow above shows a leaf segment or pinna with spore clusters or sori underneath. The next arrow points to a single The life cycle of a typical fern proceeds as follows: A diploid sporophyte phase produces haploid spores by meiosis (a process of cell division which reduces the number of chromosomes by a half). A spore grows into a free-living haploid gametophyte by mitosis (a process of cell division which maintains the number of chromosomes).
