What is triphasic life cycle in red algae ?

Explanation

### Step-by-Step Solution for the Triphasic Life Cycle in Red Algae

1. **Definition of Triphasic Life Cycle**: The triphasic life cycle in red algae refers to a life cycle that includes three distinct phases: two diploid sporophytic phases and one haploid gametophytic phase.

2. **Phases of the Triphasic Life Cycle**:
- **Haploid Gametophyte Phase**: This is the first phase where the organism exists in a haploid state. It is responsible for producing gametes (sperms and eggs).
- **Diploid Carposporophyte Phase**: This is the second phase that develops from the fertilization of the gametes. The zygote forms the carposporophyte, which is diploid and produces carpospores.
- **Diploid Tetrasporophyte Phase**: This is the third phase that develops from the carpospores produced by the carposporophyte. The tetrasporophyte is also diploid and forms tetrasporangia, which produce haploid tetraspores.
