Sporophyte - Wikipedia
A sporophyte (/ ˈspɔːr.əˌfaɪt /) 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.

孢子体 （sporophyte， / spɔːroʊˌfaɪt /）是 陆生植物 与多细胞 藻类 世代交替 过程中的多细胞 二倍体 阶段。 起始于两个 单倍体 的 配子 融合（受精）形成单细胞的二倍体的 合子。 合子再经过有丝分裂後形成多细胞的孢子体。 孢子体會通过 减数分裂 产生单倍体的 孢子。 孢子再有丝分裂形成单倍体的配子体。 成熟的配子体再产生配子。 形成世代交替的一个循环。 蕨类 与 种子植物 的孢子体远远比 配子体 更为显著与功能完善，其孢子体有 根 、 茎 、 叶 的分化。 开花植物 的配子 …

产生孢子进行 无性生殖 的世代称为孢子体世代（sporophytic generation），这个世代的生物体称为孢子体。 在 孢子 形成中，一般伴有 减数分裂 。 与此相反，形成 配子 进行 有性生殖 的，则分别称为配子世代和配子体。
Sporophyte - Definition, Function and Examples - Biology Dictionary
Mar 26, 2019 · The spores are diploid cells containing genetic information about the plant itself, thus making it capable of asexual reproduction. However, plants are also capable of sexual reproduction by means of the union of a sperm and an egg. The basic function of the sporophyte is to create spores – that much is known already.

a SPOROPHYTE I. This phase of the trigenetic cycle, often reduced and appearing absent, is intercalated between the ascogonial cell, fertilized or apogamous, and the dikaryotic ascogenous filaments described by Claussen (1912). Unsuspected for a long time (Martens, 1946), it was first defined and interpreted by Chadefaud (1953, 1960).

A sporophyte is the simple reproductive structure of bryophytes that is born on the gametophyte and produces a single terminal sporangium. It is distinguishable from other land plants by its unbranched nature and its role in the life cycle of bryophytes. AI generated definition based on: The Jehol Fossils, 2008. About this page.
