Ø The life cycle of Polysiphonia is triphasic consists of three phases. Ø These three phases are: (1). Haploid gametophytic phase (2). Diploid carposporophytic phase (3). Diploid tetrasporophytic phase. Ø Thus the life cycle is with two diploid and one haploid phase and thus the life cycle of Polysiphonia is haplodiplobiontic.
