Which generation is dominant in ferns: the sporophyte or the gametophyte?
In ferns, the dominant generation is the sporophyte.
What plants have vascular bundles and are dispersed by spores?
Ferns
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 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.
Which generation are The green leafy plants recognized as ferns?
Ferns belong to the plant generation known as Pteridophytes. They are non-flowering vascular plants that reproduce via spores. Ferns are characterized by their feathery leaves called fronds and are commonly found in moist, shady environments.
Does gametophyte generation depends on sporophyte generation in ferns?
Yes, in ferns, the sporophyte generation is dominant and produces spores that give rise to the gametophyte generation. The gametophyte generation is a smaller, independent stage that produces gametes (sperm and egg) which fuse during fertilization to form the sporophyte generation.
What is the function of spores in ferns?
The function of spores in ferns is reproduction. Spores are produced in sporangia on the underside of fern fronds, and once dispersed, they can develop into new fern plants under suitable conditions, forming a new generation.
What plants have a dominant gametophyte?
The sporophyte generation is dominant in ferns.
What life cycle components appear only in mosses and ferns?
The gametophyte generation is more prominent and independent in mosses and ferns compared to seed plants. Also, the sporophyte generation in mosses and ferns is not as prominent or long-lived as in seed plants. Finally, mosses and ferns rely on water for fertilization, a characteristic not seen in seed plants.
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.
How do tree ferns reproduce?
Ferns have sexual mode of reproduction. Also ferns can only reproduce where there is sufficient moisture to transfer their motile male gametes to the archegonia for fertilization. Mainly ferns are reproduced by spores and at a time in the year they grow small spots under their leaves, known as sori. Each sorus has several sporangia where spores (micro & megaspores) are produced. Sexual reproduction in ferns takes place by spores in sporophytic phase and by reproductive organs i. e. anthredia and archegonia in gametophytic phase. Thus, the reproduction in ferns is achieved by alternation of generation.
What plants have a prothallus that forms archegonia and antheridia and has a dominant sporophyte?
Ferns are plants that have a prothallus with archegonia and antheridia. In ferns, the sporophyte generation is dominant, meaning it is the more visible and long-lived stage of the plant's life cycle compared to the gametophyte stage.
