What is the fern Sporophyte?
Spores, rather than gametes, are the unicellular, haploid products of meiosis in fern plants. Spores in turn undergo mitotic cell divisions to produce the multicellular, haploid gametophyte. Relative to the familiar sporophytes, the fern gametophytes are small and inconspicuous.
What are the three parts of Sporophyte?
The nucleus of the megaspore undergoes mitosis to produce the egg cells that will start the sporophytic generation: two synergid cells, a large central cell, and three antipodal cells. In vascular seed-bearing plants, the sporophyte is made of the entire body of the plant except for the embryo sac and pollen.
Where is the Sporophyte in Ferns?
The first tiny leaf of the sporophyte emerges from the bottom of the gametophyte (which disintegrates) and grows upward and soon becomes a plant we see as a fern or horsetail. This mature fragile fern gametophyte is about ½ inch across and is growing on soil that is almost continually damp.
What are the different parts of ferns?
Ferns have 3 major parts – the rhizome, the fronds and the reproductive structures called sporangia. The characteristics of each of these 3 parts of the fern plant are used for classification and identification.
What part of the fern helps them to reproduce?
rhizomes
What generation in the life cycle of a fern lacks vascular tissue?
The life cycle of a fern includes a free-living gametophyte stage. It is small and inconspicuous, and lacks vascular tissue. The zygote begins life attached to the gametophyte, but soon develops into a large and independent sporophyte. The sporophyte has vascular tissue and may attain a very large size.
What is the most suitable environment for a fern?
Ferns do best in warm, but not overly hot, weather conditions. They grow best in temperatures between 73 and 86 degrees Fahrenheit. While ferns can survive and even thrive in temperatures as low as 50 degrees Fahrenheit, fungi that harm ferns can breed in colder temperatures.
