Describe the dominant stage in the life cycle of a fern?

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 are the stages in the life cycle of a fern?

bioweb. The life cycle of the fern has two different stages; sporophyte, which releases spores, and gametophyte, which releases gametes. Gametophyte plants are haploid, sporophyte plants diploid. This type of life cycle is called alternation of generations.

What is the dominant life cycle stage of a moss of a fern?

Unlike more advanced plants, mosses have a dominant haploid life stage. That is, the moss that you see is the gametophyte and only contains one set - rather than the normal two sets - of chromosomes. The haploid stage starts with a spore.

Do ferns have a dominant stage?

In higher plants like ferns and fern allies, the sporophyte stage is dominant. Gametophytes produce gametes (sperm and eggs) in a special structure called a gametangium (-ia), while sporophytes produce spores in a special structure called a sporangium (-ia).

What is the dominant life history generation of the fern?

The dominant generation in ferns is the sporophyte generation.

How ferns reproduce step by step?

Ferns do not flower but reproduce sexually from spores. There are two distinct stages of the fern life cycle. Mature plants produce spores on the underside of the leaves. When these germinate they grow into small heart-shaped plants known as prothalli.

Which generation is dominant in ferns and why?

In vascular plants, the sporophyte generation is dominant. In seedless vascular plants such as ferns, the sporophyte releases spores from the undersides of leaves. The spores develop into tiny, separate gametophytes, from which the next generation of sporophyte plants grows.

What is the dominant generation of a moss?

The sporophyte is the dominant generation, but multicellular male and female gametophytes are produced within the flowers of the sporophyte. Cells of the microsporangium within (more...) The “leafy” moss you walk on in the woods is the gametophyte generation of that plant (Figure 20.2).

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 are the stage of life cycle of a moss?

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.

What is the dominant stage of the fern life cycle What is the relationship of the fern gametophyte and sporophyte?

dominant phase during life cycle is gameteophyte in mosses, and sporophyte in ferns. Ferns are vascular while mosses are non vascular.

Why are ferns sporophyte dominant?

In vascular plants, the sporophyte generation is dominant. In seedless vascular plants such as ferns, the sporophyte releases spores from the undersides of leaves. The spores develop into tiny, separate gametophytes, from which the next generation of sporophyte plants grows.

What is the dominant generation?

In many plants, the sporophyte generation is the dominant generation. This means that the sporophyte is larger and lives longer than the gametophyte generation.

How does a fern begin the first stage of the life cycle?

Starting with the "fern" as we recognize it (the sporophyte), the life cycle follows these steps: The diploid sporophyte produces haploid spores by meiosis, the same process that produces eggs and sperm in animals and flowering plants. Each spore grows into a photosynthetic prothallus (gametophyte) via mitosis.

Which phase in the plant life cycle is dominant in the bryophytes?

The haploid stage, in which a multicellular haploid gametophyte develops from a spore and produces haploid gametes, is the dominant stage in the bryophyte life cycle. The mature gametophyte produces both male and female gametes, which join to form a diploid zygote.

Which generation is dominant in ferns and how does this compare to mosses?

Summary – Mosses vs Ferns

Also, the gametophyte is the dominant generation in mosses, while sporophyte is the dominant generation in ferns.
