What is alternation of generations in plants?

Explanation

**Step-by-Step Solution:**

1. **Definition of Alternation of Generations**: Alternation of generations is a biological term that describes the life cycle of plants, involving two distinct multicellular stages: the gametophyte and the sporophyte.

2. **Understanding the Two Generations**:
- **Gametophyte**: This stage is haploid (n), meaning it has one set of chromosomes. The gametophyte is responsible for producing gametes (sperm and eggs).
- **Sporophyte**: This stage is diploid (2n), meaning it has two sets of chromosomes. The sporophyte develops from the fertilization of gametes and is responsible for producing spores through meiosis.
