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 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.
Which stage in the alternation of generations life cycle would fern represent?
The Sporophyte life cycle is the dominant stage in Ferns (vascular non-seed plants)
What is a land plant that produces flagellated sperm and has a sporophyte dominated life cycle?
A land plant that fits this description is a fern. Ferns have flagellated sperm that require water for fertilization, and their life cycle is characterized by a dominant sporophyte stage. During fertilization, the sperm swim through water to reach the eggs on the archegonia of the female gametophyte.
Explain the stages in the life cycle of a fern?
A fern's life cycle alternates between two distinct stages: the sporophyte and gametophyte. The sporophyte stage is the dominant phase, where it produces spores through meiosis. These spores germinate into tiny gametophytes, which produce eggs and sperm. Fertilization of the egg by the sperm results in a new sporophyte plant.
What stage of a ferns life cycle do you see fiddleheads?
You will see fiddleheads in the first stage known as transition in the life cycle of a fern. The fiddleheads are delicately divided when they expand into fronds.
What does the gametophyte stage of a moss or fern life cycle produce?
The gametophyte stage of a moss or fern life cycle produces gametes (eggs and sperm) through mitosis. These gametes combine during fertilization to form a diploid zygote, which develops into the sporophyte stage.
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.
What is the shape of prothallium?
The prothallium of ferns is typically flat and heart-shaped, with a thin and delicate structure. It is the gametophyte stage in the life cycle of a fern that produces the reproductive structures.
What is shape of prothallus of fern?
flat.heart-shaped membranous structure with numerous rhizoids on its central lower surfaces.
Are sperm protected from drying out in the fern cycle?
no
What role does the dominant generation play in the life cycle of ferns?
The dominant generation in the life cycle of ferns is the sporophyte, which is the plant that produces spores. The sporophyte is the visible, leafy plant that we typically think of as a fern. It plays a crucial role in reproduction by producing spores that develop into the gametophyte, which is a smaller, less visible plant that produces eggs and sperm. The gametophyte then fertilizes and develops into a new sporophyte, completing the life cycle of ferns.
