What is the dominant stage of the fern life cycle what is the relationship of the fern gametophyte and sporophyte?
in the life cycle of a fern, the dominant and recognizable stage is the diploid sporophyte. the the younger sporophyte grows from the gametophyte.
How are the fern sporophyte and gametophyte stage the same?
In reference to the sporophyte and gametophyte, are the stages of the plant's life cycle thus being the same.
Is a snapdragon 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.
The gametophyte of a fern is?
The gametophyte of a fern is a small, independent plant that produces gametes (eggs and sperm). This stage in the fern life cycle is usually heart-shaped and photosynthetic, and it is typically found on the underside of leaves in damp environments. The gametophyte is responsible for producing the sperm and egg that will fuse to form a new sporophyte plant.
Are the cells of fern that you see haploid or diploid?
The cells of a fern plant that you see are diploid. Ferns have a lifecycle which alternates between a diploid sporophyte generation and a haploid gametophyte generation. The visible fern plant is the diploid sporophyte generation.
What is the dominant stage of the fern life cycle what is the relationship of the fern gametophyte and sporophyte?
in the life cycle of a fern, the dominant and recognizable stage is the diploid sporophyte. the the younger sporophyte grows from the gametophyte.
What is the name to the gametophype generation in fern?
Gametophyte generation of fern is called prothallus.
What cell did the sporophyte develop?
On the gametophyte, cells in the archegonium and antheridium form the eggs and sperm. The sperm swim to the egg and fertilize it, forming the zygote. The embryo develops into the sporophyte, still attached to the gametophyte.
Where are the antheridia and archegonia found in ferns?
Antheridia, the male reproductive structures, are typically found on the underside of fern leaves. Archegonia, the female reproductive structures, are usually found near the tips of young fern leaves.
Does sorus have gametophyte or sporophyte?
Sorus is a structure found on the underside of fern leaves that contains the sporangia, which produce spores. The spores give rise to the gametophyte generation in ferns.
How are the fern sporophyte and gametophyte stage the same?
In reference to the sporophyte and gametophyte, are the stages of the plant's life cycle thus being the same.
In a fern's life cycle when does fertilization occur?
Fertilization in a fern's life cycle occurs when sperm from the male gametophyte fertilizes an egg in the female gametophyte, usually happening after the sperm swims to the egg in a film of water.
How does the sporophyte generation of a plant differ from a gametophyte generation?
In most plants, the sporophyte generation is dominant. In fern, for example, the fern itself is the sporophyte. This organism produces spores that fall to the substrate below and grow into a separate organism called a gametophyte. The gametophyte produces sperm and eggs in order to produce a new sporophyte which grows out of the gametophyte's body, destroying it. It is important to note that the gametophyte is haploid and the sporophyte is dploid.
In the fern life cycle a spore germinates to form an?
In the fern life cycle, a spore germinates to form a gametophyte. This gametophyte produces male and female gametes through mitosis, which then fuse to form a zygote. The zygote develops into a new sporophyte plant.
Is a snapdragon 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.
What stage of the fern life cycle is dominant?
The sporophyte stage is dominant in the fern life cycle. It is the visible, leafy plant that produces spores through meiosis. The gametophyte stage is much smaller and less conspicuous, developing from the spores and producing the reproductive gametes.
Are the cells of fern that you see haploid or diploid?
The cells of a fern plant that you see are diploid. Ferns have a lifecycle which alternates between a diploid sporophyte generation and a haploid gametophyte generation. The visible fern plant is the diploid sporophyte generation.
