A sporophyte (/ ˈ s p ɔːr. ə ˌ f aɪ t /) is the diploid multicellular stage in the life cycle of a plant or alga which produces asexual spores. This stage alternates with a multicellular haploid gametophyte phase.

2019年3月26日 · In a plant’s life cycle, the spore-producing phase is called sporophyte. There are two stages of reproduction in plants: sexual and asexual. Through the process of meiosis and fertilization, the alternation of generation segregates these two …

2019年7月11日 · The sporophyte forms from a fertilized egg inside the flask-like archegonium and attaches to the gametophyte via a penetrating foot. The sporophyte receives nourishment from the gametophyte. The sporophyte forms a very small stalk called a seta and a single sporangium.

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.

2024年6月8日 · Sporophyte Generation. The diploid zygote remains within the archegonium and grows into the sporophyte, which is nutritionally dependent on the gametophyte. The sporophyte consists of three main parts: Foot: Anchors the sporophyte to the gametophyte. Seta: A stalk that elevates the sporangium.

2021年2月27日 · In plants, the sporophyte generation is that phase in their life cycle that begins with the union of two single-celled haploid gametes. This union of haploid (n) gametes results in the formation of a single-celled diploid (2n) zygote. The zygote germinates and grows by going through a series of mitotic divisions.

2023年8月3日 · While the sporophyte generation predominates in angiosperms and gymnosperms, the gametophyte generation is the primary life phase in bryophytes like mosses and liverworts. In fungi, the haploid phase predominates as well. Many species of algae also alternate between the sexual and asexual phases.

2022年4月15日 · What is a sporophyte? Accordingly, the sporophyte is the plant generation that produces spores. To preserve their plant species and reproduce, the plant life cycle alternate between the haploid stage (i.e., a single set of the chromosome) and the diploid stage (i.e., two sets of the chromosome).

2023年11月21日 · In many plants, the sporophyte generation is the dominant generation. This means that the sporophyte is larger and lives longer than the gametophyte generation.

2018年4月28日 · The sporophyte structure is dependent upon the gametophyte of nourishment because only the gametophyte is capable of photosynthesis. The gametophyte generation in these organisms consists of the green, leafy or moss-like vegetation located at …
