Are archegonia haploid or diploid?
Archegonia are haploid structures found in plants. They are part of the female reproductive structure and are responsible for producing the egg cells.
What is the name given to the life cycle of plants which includes a sporophyte generation and a gametophyte generation?
Plants exhibit alternation of generations that includes both diploid and haploid multicellular stages.The multicellular diploid stage is called the sporophyte and haploid stage is called gametophyte.
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.
What is the function of meiosis in the life cycle of a fern?
Meiosis in ferns is responsible for producing spores, which are haploid reproductive cells. These spores develop into gametophytes, which produce gametes through mitosis. When the gametes fuse, they form a zygote that grows into a new diploid fern plant, completing the fern life cycle.
What generation is dominant in ferns and how does it contribute to their reproductive cycle?
The dominant generation in ferns is the sporophyte generation. This generation produces spores through meiosis, which then develop into gametophytes. The gametophytes produce gametes that fuse to form a new sporophyte, completing the reproductive cycle of ferns.

What is alternation of generation?
It is a type of life cycle found in some algae, fungi, and all plants where an organism alternates between a haploid (n) gametophyte generation and a diploid (2n) sporophyte generation. A diploid plant (sporophyte) produces, by meiosis, a spore that gives rise to a multicellular, haploid pollen grain (gametophyte). It once was called hydrogen power. In more simple terms, it is a life cycle in which there is both a multicellular diploid form, and a multicellular haploid form.
What structure in ferns is diploid?
In ferns, the diploid structure is the sporophyte, which is the dominant phase of their life cycle. The sporophyte consists of the leafy fronds and the underground rhizome. It produces spores through meiosis in specialized structures called sporangia, which are typically located on the undersides of the fronds. These spores are haploid and develop into the gametophyte stage, completing the life cycle.
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.

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 the difference between the life cycle of ferns and the life cycle of humans?
The life cycle of a fern includes both a gametophyte and sporophyte generation. A diploid zygote formed on the gametophyte develops into a sporophyte, a fern. The sporophyte releases haploid spores that germinate into gametophytes. The life cycle of a conifer consists of male and female cones produced on an adult plant, the sporophyte. The male produces pollen grains that fertilize eggs retained within the female cone. The fertilized egg develops into a seed. When released and conditions are favorable, the seed germinates into a young sporophyte.
Why do ferns have a dominant gametophyte?
Ferns have a dominant gametophyte stage because their life cycle alternates between a haploid gametophyte and a diploid sporophyte. In ferns, the gametophyte is often photosynthetic and independent, allowing it to thrive in various environments, while the sporophyte is typically larger and more complex. This dominance of the gametophyte allows for effective reproduction and dispersal, as it can produce gametes that will develop into new sporophytes. Additionally, the gametophyte's ability to survive in a range of conditions enhances the overall adaptability of ferns.
What is the dominant generation in ferns and how does it contribute to the reproductive cycle of these plants?
The dominant generation in ferns is the sporophyte, which is the larger and more visible stage of the plant. The sporophyte produces spores through meiosis, which then develop into the gametophyte stage. The gametophyte produces gametes (eggs and sperm) through mitosis, which then fuse to form a new sporophyte, completing the reproductive cycle of ferns.
