Which generation in ferns is the dominant generation and why?

The diploid sporophyte generation is dominant in ferns. The haploid gametophyte is a small and inconspicuous prothallus. But it is multicellular and photosynthetic.

What is the major difference between the alternation of generations in the life cycles of bryophytes?

Vascular plants have true xylem and phloem. Alternation of generations of sporophytic and gametophytic generation occurs in both. In Bryophytes, main plant is gametophyte and sporophyte is reduced and parasitic on gametophyte, whether complete or partial.

What are the two generations in the fern life cycle?

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 does the alternation of generations in ferns show?

The alternation of generations allows for both the dynamic and volatile act of sexual reproduction and the steady and consistent act of asexual reproduction. When the sporophyte creates spores, the cells undergo meiosis, which allows the gametophyte generation to recombine the genetics present.

How is alternation of generations different in ferns and pines?

How is alternation of generations different in ferns and pines? Alternation of generations is different in ferns and pines in many ways. Ferns have two generations (haploid gametophyte and diploid sporophyte) that exist independently while in pines the sporophyte is the dominant generation.

What is the major difference between fern and moss life cycles?

Also, both mosses and ferns show alternation of generation. But, the dominant phase of the life cycle of mosses is the haploid gametophyte generation, while the dominant phase of the life cycle of ferns is the diploid sporophyte generation. Therefore, this is another important difference between mosses and ferns.

How does alternation of generation differ from Metagenesis?

alternation of generations, also called metagenesis or heterogenesis, in biology, the alternation of a sexual phase and an asexual phase in the life cycle of an organism. The two phases, or generations, are often morphologically, and sometimes chromosomally, distinct. ... Life cycle of moss.

What is the difference between Homosporous alternation of generations and Heterosporous alternation of generations?

Plants that produce only one type of spore are called homosporous and the resultant gametophyte produces both male and female gametes, usually on the same individual. ... Plants that produce two types of spores are called heterosporous.

What is the difference between the alternation of generations in the life cycles of bryophytes and seedless vascular plants?

Both bryophytes and seedless vascular plants are primitive plants. Both show alternation of generations. But, in bryophytes, the gametophyte is dominant while in seedless vascular plants, the sporophyte is dominant. ... Thus, this summarizes the difference between bryophytes and seedless vascular plants.

Why does fern reproduction require two generations?

The fern life cycle requires two generations of plants to complete itself. This is called alternation of generations. One generation is diploid, meaning it carries two identical sets of chromosomes in each cell or the full genetic complement (like a human cell). ... A fern's spores don't grow into leafy sporophyte.

Do ferns have sperm?

The sex organs of ferns are of two types. The sperm-producing organ, the antheridium, consists of a jacket of sterile cells with sperm-producing cells inside. ... Fertilization is attained by the ejection of sperm from antheridia.

How do ferns differ from other seedless vascular plants quizlet?

Ferns and mosses are alike in one way: both reproduce by spores instead of seeds. However, ferns are different from mosses because they have vascular tissue that distributes water and nutrition to all plant cells. ... Explain what fossil records tell about seedless plants that lived on Earth long ago.

How do a fern sporophyte and a moss sporophyte differ?

The sporophyte of ferns is differentiated into true leaves, stem, and roots. In contrast, mosses lack true leaves, stem or roots. Ferns are vascular plants, but mosses are not.

Why is it called alternation of generations?

The multicellular haploid plant structure is called the gametophyte, which is formed from the spore and give rise to the haploid gametes. The fluctuation between these diploid and haploid stages that occurs in plants is called the alternation of generations.

What is the difference in the alternation of generations of vascular plants from non vascular plants?

The life cycle of both the plants are same, that means both types of plants go through the alternation of generations, but in vascular plants dominating phase is sporophyte, which is diploid and in non-vascular plants dominating generation is gametophyte, and second is sporophyte.

How does the sporophyte generation of a plant differ from the gametophyte generation?

What is the difference between a Sporophyte and a Gametophyte? Sporophyte phase produces spores, while gametophyte phase produces gametes (egg and sperms). Therefore, sporophyte phase is asexual, while gametophyte phase is sexual.

How does the alternation of generations life cycle of seed plants differ from that in seedless plants?

The difference between seed plants and seedless plants is that seedless plants do not bear seeds for propagation, whereas seed plants bear seeds for multiplication. ... Seed plants mainly multiply by seeds. Seedless plants multiply by spores that may produced asexually or as a consequence of asexual reproduction.
