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.
The sporophyte is the multicellular diploid stage of the plant life cycle. This structure will eventually create the haploid spores by the process of meiosis. Meiosis-also called sexual reproduction-creates four cells that are genetically different and haploid.
