Nephrolepis Sporophyte Diagram. Habit and Habitat of Nephrolepis. Habit and Habitat of Equisetum 2.
Then a prepared slide of a fern prothalli with sporophyte attached was obtained and examined under the microscope. Nephrolepis is a genus of about 30 species of fernsIt is the only genus in the family Nephrolepidaceae placed in the suborder Aspleniineae eupolypods I of the order Polypodiales in the Pteridophyte Phylogeny Group classification of 2016 PPG I. The mature fern plant is the sporophyte structure that produces spores which are released from sporangia.
Alternation of generations also known as metagenesis is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages.
These species are distributed in the tropics of the entire. Draw a diagram to show the basic morphology of this sporophyte ii Mount some sporangia from this fern in water on a microscope slide. Since the sword fern originates from tropical regions it is not used to the cold and will die at temperatures below 10 degrees celsius. Having looked at these under the microscope irrigate the slide with 90 ethanol watching the sporangia all the while.
