Which generation-gametophytic or sporophytic is well developed in bryophytes ?

Explanation

### Step-by-Step Solution:

1. **Understanding Bryophytes**:
- Bryophytes are non-vascular plants that include mosses, liverworts, and hornworts. They exhibit a life cycle that alternates between two generations: the gametophyte and the sporophyte.

2. **Identifying Generations**:
- The **gametophyte** generation is haploid (n) and produces gametes (sperm and eggs).
- The **sporophyte** generation is diploid (2n) and produces spores through meiosis.
