Which process occurs in the life cycle of a moss but not in the life cycle of a gymnosperm?

• A. Dominant gametophyte stage
• B. Seed production
• C. Alternation of generations
• D. Pollination

Answer: (A)

Verified step by step guidance

1. Understand the life cycle of mosses: Mosses are non-vascular plants that have a dominant gametophyte stage, meaning the gametophyte is the most conspicuous and long-lived phase of their life cycle.
2. Understand the life cycle of gymnosperms: Gymnosperms are vascular plants that have a dominant sporophyte stage, where the sporophyte is the most visible and long-lived phase.
3. Identify the unique feature of mosses: In mosses, the gametophyte stage is dominant, which is not the case in gymnosperms where the sporophyte stage is dominant.
4. Compare the processes: Seed production and pollination are processes associated with gymnosperms, while alternation of generations occurs in both mosses and gymnosperms.
5. Conclude the unique process: The dominant gametophyte stage is a process that occurs in the life cycle of a moss but not in the life cycle of a gymnosperm.
