What does it mean to say that a life cycle is dominated by the gametophyte versus the sporophyte stage?
When a life cycle is dominated by the gametophyte stage, it means that the plant spends most of its life as a haploid gametophyte producing gametes. Conversely, when a life cycle is dominated by the sporophyte stage, the plant spends most of its life as a diploid sporophyte producing spores.
Do the spores belong to the gametophyte or the sporophyte generation?
Spores belong to the sporophyte generation in the plant life cycle. They are reproductive structures that develop from sporangia on the sporophyte and give rise to the gametophyte generation through germination.
What are the two alternating phases of a plants life cycle?
The two alternating phases of a plant's life cycle are the reproductive phase (gametophyte) where plants produce gametes, and the vegetative phase (sporophyte) where plants grow and develop. The gametophyte phase produces gametes through meiosis, which then fuse during fertilization to form a new sporophyte plant.
What do gametophyte produce during a plant life cycle?
Gametophytes produce gametes (eggs and sperm) during the plant life cycle. These gametes will fuse during fertilization to form a zygote, which will develop into a new sporophyte plant.
In which group of plants are both the sporophyte and gametophyte free-living?
In ferns, both the sporophyte (diploid) and gametophyte (haploid) are independent and free-living stages in the life cycle. The sporophyte is the leafy plant we typically see, while the gametophyte is a small, independent structure that produces gametes.
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 are the two major stages of a plant life-cycle?
The Sporophyte stage and the gametophyte stage

What is a gametophyte and sporophyte?
gametophyte: The gamete-bearing individual or phase in the life cycle of a plant having alternation of generations sporophyte: The spore-producing individual or phase in the life cycle of a plant having alternation of generations
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.
The green leafy moss plant is part of what moss cycle?
The green leafy moss plant is part of the gametophyte phase of the moss life cycle. Mosses alternate between a gametophyte stage (producing male and female gametes) and a sporophyte stage (producing spores).
What is the main function of a mature sporophyte?
The main function of a mature sporophyte is to produce spores through meiosis, which will develop into gametophytes. The sporophyte is the diploid, spore-producing phase of the plant life cycle, while the gametophyte is the haploid, gamete-producing phase.
What are sporophyte and gametophyte?
Two different forms a plant can have.
