Question

The dominant generation in the life cycle of an angiosperm is:

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Alternation of generations in plants
 **Related Topics**: Angiosperm life cycle, sporophyte, gametophyte, meiosis, mitosis
 **Prerequisites**: Basic understanding of plant reproduction and life cycles.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the dominant generation in the angiosperm life cycle.
  The options are: Gametophyte, Sporophyte, Both equally dominant, None of the above.
**Method & Steps**:
 1. Understand the concept of alternation of generations.
  Reasoning: Plants exhibit alternation of generations, switching between a haploid gametophyte (gamete-producing) and a diploid sporophyte (spore-producing) generation.
  Formula/Rule: None directly applicable, but understanding the relative sizes and lifespans of the generations is key.
 2. Consider the angiosperm life cycle.
  Working: In angiosperms (flowering plants), the sporophyte generation is the dominant, large, and long-lived phase. The gametophyte generation is significantly reduced and dependent on the sporophyte. The sporophyte is what we typically recognize as the plant itself (roots, stems, leaves, flowers).
  Key Point: The gametophyte is microscopic in angiosperms and is contained within the flower's structures (pollen grains and embryo sac).
 3. Determine the dominant generation.
  Result: The sporophyte is the dominant generation in the angiosperm life cycle.
  Verification:  Observe a flowering plant; the visible plant body is the sporophyte. The gametophytes are the pollen and ovules, which are much smaller and shorter-lived.
 ## OPTION ANALYSIS
A :x: Gametophyte is the reduced generation in angiosperms.
B ✓: Sporophyte is the dominant, visible generation in angiosperms.
C :x: Gametophyte and sporophyte are not equally dominant in angiosperms; the sporophyte is dominant.
D :x: One of the options is correct.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing the sporophyte and gametophyte: Remembering that the sporophyte is diploid (2n) and produces spores through meiosis, while the gametophyte is haploid (n) and produces gametes through mitosis can help.
  2.Overlooking the reduced nature of the angiosperm gametophyte:  The microscopic size and dependence on the sporophyte are crucial distinguishing features.
 **Quick Tips**:
  1.Remember that the dominant generation is the one that is larger and longer-lived.
  2.Visualize the flowering plant – the large plant body is the sporophyte.
