What is the function of a gametophyte?
A major function of the gametophyte generation is to produce haploid gametes. Fusion of the egg cell with the sperm cell gives rise to the sporophyte, thereby completing the life cycle (Raven et al., 1992). In many lower plants, gametophytes are the dominant and free-living generation.
What is the function of a sporophyte?
The sporophyte's primary purpose is to produce spores. The spores, in turn, form gametophytes, which give birth to male and female gametes via the meiotic process. Following this step, the reproductive cells are ready to be fertilised in order to generate the sporophyte, completing the cycle.

What is a sporophyte in simple terms?
sporophyte, in plants and certain algae, the nonsexual phase (or an individual representing the phase) in the alternation of generations—a phenomenon in which two distinct phases occur in the life history of the organism, each phase producing the other.
What is a sporophyte kid definition?
Kids Definition
sporophyte. noun. spo·ro·phyte ˈspōr-ə-ˌfīt. ˈspȯr- : the individual or generation of a plant having alternating sexual and asexual generations that produces asexual spores compare gametophyte.
How do you identify a sporophyte?
The sporophyte is diploid and has a multicellular structure, which means it contains two sets of chromosomes, one from each parent. They will undergo meiotic division (asexual mode of reproduction) and give rise to meiospores. These meiospores are haploid structures that will eventually grow into haploid gametophytes.Mar 2, 2022
What role does the sporophyte play in the plant life cycle?
The sporophyte produces spores by meiosis. The spores grow into gametophytes. The gametophytes produce gametes (eggs and sperm). Fusion of gametes (fertilization) produces a zygote.Jun 13, 2020
What is the purpose of the sporophyte in plants?
The sporophyte's primary purpose is to produce spores. The spores, in turn, form gametophytes, which give birth to male and female gametes via the meiotic process. Following this step, the reproductive cells are ready to be fertilised in order to generate the sporophyte, completing the cycle.
What is the role of the sporophyte in the fern life cycle?
Plants we see as ferns or horsetails are the sporophyte generation. The sporophyte generally releases spores in the summer. Spores must land on a suitable surface, such as a moist protected area to germinate and grow into gametophytes.
Which one is the sporophyte generation in the life cycle of this plant?
The sporophyte is the dominant generation, but multicellular male and female gametophytes are produced within the flowers of the sporophyte.
How does the role of the sporophyte and gametophyte change in the life cycles of the land plants?
During their life cycles, both brown algae and land plants alternate between two multicellular forms: the gametophyte and the sporophyte. The gametophyte develops sexually active reproductive cells, which, when they merge, create the sporophyte. In turn, spores produced by the sporophyte give rise to the gametophyte.Jan 15, 2019
