Bryophytes, the group of non-vascular plants that includes mosses, liverworts, and hornworts, are essential for understanding plant evolution. These plants are unique in their life cycles, displaying distinct gametophyte and sporophyte generations.
Bryophytes are among the simplest and oldest land plants. They are primarily found in moist, shaded environments and are characterized by their lack of true vascular tissues, roots, stems, and leaves. Instead, they have structures that serve similar functions: rhizoids (for anchorage), thalli or leafy shoots (for photosynthesis), and simple conducting tissues.
Gametophyte Evolution
Dominant Phase
In bryophytes, the gametophyte is the dominant phase of the life cycle, which contrasts with most other land plants where the sporophyte is dominant. The gametophyte is haploid, meaning it contains a single set of chromosomes.
Structural Adaptations
- Moss Gametophytes: Typically form dense, green mats or cushions. They possess simple leaves arranged spirally around a central stem-like structure.
