Compare and contrast the nutritional needs of the gametophyte and the sporophyte of mosses and spore-bearing vascular plants and seed-bearing vascular plants?
The gametophyte of moss is the dominant structure
In which group of plants are both the sporophyte and gametophyte free- living?
Both the sporophyte and gametophyte are free-living and homomorphic, and belong to Cladophora.
In which group of plants are both the sporophyte and gametophyte free-living?
ferns
Can flowering plants reproduce by spores?
Yes the spores are like seeds. They drop off of a fern and onto the ground and sooner or later they sprout and makes a new fern. Spores are not like seeds. They lack a seed coat, endosperm and preformed embryonic parts. In addition spores give rise to the gametophyte generation and seeds give rise to the sporophyte generation. Ferns and mosses do both reproduce by using spores BUT mosses have a reduced almost parasitic sporophyte generation which produces the spores. These spores will produces the gametophyte generation (the green leafy thing we see). The gametophyte produces the sex cells that fuse to make a zygote. This zygote then forms a new sporophyte. With ferns the sporophyte generation is more dominant than the gametophyte. The leafy structure we see is the sporophyte.
What are the two stages of plant life?
Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle. The plants which we call mosses and ferns are the gametophyte generations. However conifers and flowering plants are the sporophyte generation of their life cycle. This is much easier to understand if you see a diagram.
Does the gametophyte of ferns depends on sporophyte generation?
The sporophyte of a fern, destined to grow to be magnitudes larger than the prothallium, destroys the prothallium as it grows.
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.

The gametophyte of moss is the dominant structure

ferns
In which group of plants are both the sporophyte and gametophyte free-living?
ferns
Which generation is dispersed in ferns?
the sporophyte generation
Is the sporophyte stage of a moss much larger than the gametophyte stage?
Ferns have a dominant sporophyte and a reduced gametophyte. As for moss, it depends on the type. If referring to mosses under the phylum Bryophyta (these are the nonvascular mosses) they have a dominant gametophyte. If referring to mosses under seedless vascular category, such as club mosses in the phylum Lycophyta, these plants have a dominant sporophyte and a reduced gametophyte.
What is tha name given to the gametophyte generation in ferns?
Prothallium is the name given to the gametophyte generation in ferns. Another term given to these species of ferns is prothallus.
What stage is dominant in ferns?
the Sporophyte generation
Which feature do ferns share with all other land plants?
Sporophyte and Gametophyte life cycles.
