Pheophytin or phaeophytin (abbreviated Pheo) is a chemical compound that serves as the first electron carrier intermediate in the electron transfer pathway of Photosystem II (PS II) in plants, and the photosynthetic reaction center (RC P870) found in purple bacteria.
Usually, the sporophyte gives rise to haploid spores which germinate to produce a haploid generation (the gametophyte stage) that will produce the gametes. In ferns, horsetails, conifers and angiosperms, the diploid sporophyte is the dominant phase of the life cycle, the plant body we usually see. In mosses and liverworts, the main plant body is the gametophyte. Pick a style below, and copy the text for your bibliography.
