In both mosses and ferns, moisture is required for sperm to reach the egg. In mosses, the gametophyte is the dominant stage of the life cycle; in ferns, the sporophyte is the dominant stage of the life cycle. ... mature sporophytes produce haploid spores, dispersed by the wind.
What feature is common to both a moss and a fern?
What are the Similarities Between Mosses and Ferns? Both mosses and ferns are plants with primitive origins. They produce spores instead of seeds. They grow well in moist, shady locations .
What do the moss life cycle and the fern life cycle have in common quizlet?
They both have to do with spores, and the alteration of spotophyte and gametophyte . Why is water necessary for the sexual reproduction of bryophytes and ferns? Because when water touches the top of the antheridium the sperm is released in an bryophytes.
How are ferns and moss plants similar and different?
The key difference between mosses and ferns is that mosses are small spore-producing non-vascular plants , while ferns are spore-producing vascular plants. ... Bryophytes are non-vascular small plants growing in moist and shady places. Mosses and liverworts are bryophytes. Pteridophytes are the first vascular plants.
What are two ways in which the fern life cycle differs from the moss life cycle?
The fern life cycle differs from that of a moss: – Much greater development, independence and dominance of the fern’s sporophyte .
Which generation is dominant in the moss life cycle quizlet?
The gametophyte is the dominant stage of the life cycle in both mosses and ferns.
What do all plant life cycles have in common?
All life cycles have a few things in common: they start with seeds, eggs, or live birth , then involve multiple steps including reproduction, and then they end in death. The cycle repeats for millions of years.
What are three characteristics 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 do gymnosperms have that ferns do not?
Gymnosperms require wind to pollinate but ferns need water for the sperm to swim through. Gymnosperms have wood lignin and cork cambium, are more structurally rigid and thick because of layers of dead secondary vascular tissue. Ferns do not have wood or bark .
Why do ferns and mosses need to live in wet areas?
The vascular tissues in the more advanced ferns and “fern allies” are made up of xylem and phloem, which conduct water, nutrients, and food throughout the plant body. ... Their flagellated sperm must swim through water to reach the egg . So mosses and liverworts are restricted to moist habitats.
Which life cycle is dominant in ferns?
The dominant part of the life cycle, i.e., the plant that is recognized as a fern, represents the sporophyte generation . The gametophyte generation includes the phase of the life cycle between the formation of spores by meiosis and fertilization and formation of the zygote.
What do ferns have that apple trees dont?
Ferns have spores while apple trees do not have spores. Spores are part of the reproductive process of ferns and grow into temporary plants that...
Why are ferns found in moist places?
Mosses and ferns are found in moist and shady places because both require the presence of water for sexual reproduction . As fertilization takes place only in the presence of water, through motile antherozoids that swim to reach the archegonium.
What is the difference between moss and fern?
Ferns have large compound leaves divided into many leaflets. Mosses have no true leaves , just tiny green shoots. Some ferns can grow higher than 15 feet. Mosses are limited to about an inch.
What is the major evolutionary step that separates mosses from ferns group of answer choices?
The main difference between mosses and ferns is that mosses are non-vascular plants whereas ferns are vascular plants . Furthermore, the plant body of ferns is differentiated into true leaves, stem, and roots. In contrast, the plant body of mosses consists of less differentiated leaflets.
What is the moss life cycle?
The life cycle of a moss, like all plants, is characterized by an alternation of generations . A diploid generation, called the sporophyte, follows a haploid generation, called the gametophyte, which is in turn followed by the next sporophyte generation.
