tetrasporophyte
Quick Summary
The term "tetrasporophyte" refers to a plant that bears tetraspores. In the life cycle of certain red algae, such as Polysiphonia, a tetrasporophyte is a diploid stage that develops from a carposporophyte. This tetrasporophyte undergoes meiosis to produce haploid tetraspores. These tetraspores then germinate to form either male or female gametophytes, thus continuing the reproductive cycle. This is part of a complex alternation of generations found in some algae, where sporophyte and gametophyte phases alternate.123

algaeReproduction and life histories…diploid carpospores that develop into tetrasporophytes. Certain cells of the tetrasporophyte undergo meiosis to produce tetraspores, and the cycle is repeated. In the life cycle of Polysiphonia, and many other red algae, there are separate male and female gametophytes, carposporophytes that develop on the female gametophytes, and separate tetrasporophytes.
