This indicates how strong in your memory this concept is. Carrageenin is an agarlike compound obtained from red algae that is widely used as a stabilizer in paints, pharmaceuticals, and ice cream. Plant-like protists are collectively called: protozoans algae diatoms pseudopodia. Spores produced by meiotic division in the sporophyte give rise to new gametophytes, completing the cycle, in plants that have alternation of generations, the haploid (n) , gamete producing generation or phase, the spore producing, diploid (2n) phase in a life cycle characterized by alteration of generations, the diploid (2n) cell resulting from the fusion of male and female gametes, a haploid reproductive cell; gametes fuse in pairs to form zygotes, which are diploid, a reproductive cell, usually unicellular, capable of developing into an adult without fusion with another cell, the two successive nuclear divisions in which the chromosome number is reduced from the diploid (2n) to haploid (n) and segregation of the gene occurs; as a result, gametes or spores are produced, a process during which the duplicated chromosomes divide longitudinally and the daughter chromosome then separate to form two genetically identical daughter nuclei; usually accompanied by cytokinesis, the fusion of two gamete nuclei to form a diploid zygote, a group of water-soluble accessory pigments, including phycocyankns and phycoerythrins, found in red algae and cyanobacteria, close relatives of land plants; all extant charophytes are aquatic (non-marine); sporopollein protects the zygotes, mostly freshwater (some marine and terrestrial); some are unicellular (Clamydomonas); some are colonial (Volvox); and some are unicellular (Ulva).
