Seedless vascular plants are classified into three phyla namely the club mosses, horsetails and ferns. Ferns form the numerous seedless plants with true vascular tissue, creeping underground stems called the rhizomes and large leaves called the fronds. They reproduce via spores.
Ferns crowd on the forest floors even after cutting them down. They invade the cleared zone of forest which has been cut for timber via numerous spores. The spores are in clusters called sori on the underside of the leaves. The spores develop into haploid gametophytes by mitosis. They also grow by spreading their rhizomes or from the tips of their fronds.
Cutting the clusters would prevent ferns from invading a forest cut to produce wood if the clusters were cut before ripening.
Explanation:
Fern is a spore-forming plant. These spores can be spread by wind, water and animals allowing for other areas, allowing them to germinate and give rise to other ferns.
In the fern leaves, the spores appear in the reproductive season, they stay inside closed clusters, which open when they reach a certain maturity allowing the spores to invade other areas.
If you want the ferns not to invade a certain area, you must cut the clusters before they mature.
To increase the chance of finding this species, what is suggested is to increase the number of samples evaluated in the person's microbiome. On the one hand we can increase the sample size or the number of samples of the experiment. Another possibility is to take samples from different parts of the body.
Neurospora is an ideal organism to study the effects of genetic mutations because it is easier to growth and are simple. Neurospora crassa is used as a model organism because it has a haploid life cycle and easier to grow that makes genetic analysis simple. Analysis of genetic recombination is facilitated by the ordered arrangement of the products of meiosis in Neurospora ascospores so due to simple growth and haploid life cycle we can considered Neurospora is an ideal organism.
