Plant reproductive morphology be identical isospores or come in different sizes (microspores and megaspores), but strictly speaking, spores and sporophytes are neither male nor female because they do not produce gametes. The alternate generation, the gametophyte, produces gametes, eggs and/or sperm. A gametophyte can be monoicous (bisexual), producing both eggs and sperm or dioicous (unisexual), either female (producing eggs) or male (producing sperm). In the bryophytes (liverworts, mosses and hornworts), the sexual gametophyte is the dominant generation. In ferns and seed plants (including cycads, conifers, flowering plants, etc.) the sporophyte is the dominant generation. The obvious visible plant, whether a small herb or
Second-generation immigrants in the United States conflict between that of their parents and that of mainstream U.S. society. The process by which these second-generation immigrants assimilate into society is increasingly being researched, and multiple theories on the cultural assimilation of second-generation immigrants have been proposed. The theory of segmented assimilation for second-generation immigrants is highly researched in the sociological arena. Segmented assimilation focuses on the notion that people take different paths in how they adapt to life in the United States. This theory states that there are three main different paths of assimilation for second-generation immigrants. Some immigrants assimilate smoothly into the white middle class of
