Select the correct statement describing the life cycle of angiosperms.

• A. The dominant generation in angiosperms is the diploid sporophyte.
• B. Angiosperms have a dominant haploid gametophyte generation.
• C. Angiosperms do not undergo alternation of generations.
• D. The gametophyte generation in angiosperms is larger and longer-lived than the sporophyte.

Answer: (A)

Verified step by step guidance

1. Understand the concept of alternation of generations: Angiosperms, like all plants, undergo alternation of generations, which means they alternate between a haploid gametophyte generation and a diploid sporophyte generation during their life cycle.
2. Identify the dominant generation in angiosperms: In angiosperms, the diploid sporophyte generation is dominant, meaning it is larger, more complex, and longer-lived compared to the haploid gametophyte generation.
3. Clarify the role of the gametophyte generation: The haploid gametophyte generation in angiosperms is reduced in size and duration. It exists as a small structure within the flower (e.g., pollen grains and embryo sac) and is dependent on the sporophyte for nutrients and support.
4. Evaluate the incorrect statements: Angiosperms do undergo alternation of generations, so the statement claiming they do not is incorrect. Additionally, the gametophyte generation is not larger or longer-lived than the sporophyte generation, making that statement incorrect as well.
5. Select the correct statement: Based on the above analysis, the correct statement is that the dominant generation in angiosperms is the diploid sporophyte.
