Does the sporophyte of a plant looks the same as the gametophyte?
No,they usually look quite different
What is a plant's lifecycle?
Depends on the plant: If it is a bryophyte, most of the time is spent in the gametophyte stage, until a sperm and egg fertilize. Once that happens the plant goes to the sporophyte stage, where spores are released to create more gametophytes. In seedless vascular plants, such as ferns, the plant still starts in the gametophyte (until fertilization) but the majority of the cycle is spent in the sporophyte stage (release spores to create new gametophytes). Seed bearing vascular plants have both stages at the same time but the sporophyte stage is not seen, all takes place in the flower.
Is the gametophyte of the fern monoecious or dioecious?
The gametophyte of the fern is monoecious since both the male and female sexual parts (termed antheridia and archegonia) are both on the same plant. I don't think there are any extant dioecious ferns.
Which structures represents the sporophyte stage of the bryophytes?
The sporophyte stage of bryophytes is the stalk that arises from the main plant body of a moss plant. The other sporophytes represent the same thing in other plants.
The life cycle of fern?
Ferns are vascular plants differing from the more primitive lycophytes by having true leaves (megaphylls). They differ from seed plants (gymnosperms and angiosperms) in their mode of reproduction - lacking flowers and seeds. Like all other vascular plants, they have a life cycle referred to as alternation of generations, characterized by a diploid sporophytic and a haploid gametophytic phase. Unlike the gymnosperms and angiosperms, the ferns' gametophyte is a free-living organism. Life cycle of a typical fern: # A sporophyte (diploid) phase produces haploid spores by meiosis; # A spore grows by mitosis into a gametophyte, which typically consists of a photosynthetic prothallus # The gametophyte produces gametes (often both sperm and eggs on the same prothallus) by mitosis # A mobile, flagellate sperm fertilizes an egg that remains attached to the prothallus # The fertilized egg is now a diploid zygote and grows by mitosis into a sporophyte (the typical "fern" plant).
Do vascular plants produce antheridia and archegonia on the same gametophyte?
Only in those cases where spores are not differentiated into micro- & megaspores for developing the gametophytes. Thus homosporous vascular plants produce archegonia and antheridia on same gametophyte.
Meiosis in plants?
start with a diploid sporophyte and meiosis starts with DNA replication and reduction division. You then have 4 haploid spores, meiospores. The haploid spores develop into haploid gametopytes, which produces egg and sperm by mitosis. ..In conclusion meiosis with plants is the same as in animals, the names are just a little different, ie. sporophyte, spores gametophyte. Also the process of meiosis in is a process called Alternation of generation's. It is the life cycle for plants. You cannot talk about meiosis in plant without explaining the whole life cycle of plants.

What are examples of fractals in everyday life?
Examples of fractals in everyday life would be for example a fern. A fern is a type of leaf with a certain pattern. This pattern is the fractal because as you zoom in on the fern the pattern remains the same. It is the same thing over and over again no matter how far you look into it. This happens because of the fractal dimension.
What are some types of evidence that show Earth's crust has moved?

What do moss fern and liverwort have in common?
1. They are both reproduced by spores, they have no flowers and both need the same condition stogerminate;2. Both are cryptograms that is there sexual organs are hidden;3. Both have alternations of generations with multi-cellular haploid and diploid stages;4. Grow in rain forests in tropical areas and along the western coast of the US;5. Need water to reproduce;6. Spores carry by wind/waterzsemicolumzAdditionallyIn both species, the gametophyte generation is the dominant generation (haploid stage). Also, both species lack true roots, stems, or leaves and do not have vascular tissue (xylem and phloem).
