Question

In most angiosperms, what is the dominant life cycle stage?

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B. Sporophyte
## CONCEPT FRAMEWORK
 **Primary Concept**: Alternation of generations in plants
 **Related Topics**: Angiosperm life cycle, sporophyte, gametophyte, spores, gametes
 **Prerequisites**: Basic understanding of plant reproduction and life cycles.
## SOLUTION PATHWAY
**Given Information**: The question asks about the dominant life cycle stage in most angiosperms.
**Method & Steps**:
 1. Recall the alternation of generations in plants.  Angiosperms, like other plants, exhibit an alternation of generations between a haploid gametophyte stage and a diploid sporophyte stage.
  Reasoning: The dominant stage is the one that is larger, more conspicuous, and longer-lived.
  Formula/Rule: None directly applicable.
 2. Consider the characteristics of the sporophyte and gametophyte stages in angiosperms.
  Working: The sporophyte is the diploid, multicellular stage that produces spores through meiosis. The gametophyte is the haploid, multicellular stage that produces gametes through mitosis. In angiosperms, the sporophyte is the dominant stage, while the gametophyte is reduced and dependent on the sporophyte.
  Key Point:  The sporophyte is the plant we typically see (the leaves, stem, roots, and flowers).
 3. Identify the dominant stage.
  Result: The sporophyte is the dominant stage in the angiosperm life cycle.
  Verification: This is a well-established fact in botany.
 ## OPTION ANALYSIS
A :x: Gametophyte is the reduced, less conspicuous stage in angiosperms.
B ✓: Sporophyte is the dominant, multicellular, diploid stage.
C :x: Spores are haploid reproductive cells, not a life cycle stage.
D :x: Zygote is the diploid cell formed after fertilization, not a dominant life cycle stage.
 ## LEARNING AIDS
 **Common Mistakes**: Confusing sporophyte and gametophyte stages.
  1. [Error 1]: Mistaking the gametophyte as the dominant stage due to its role in producing gametes.
   [How to avoid]: Remember that dominance refers to size, longevity, and visual prominence, not just reproductive function.
  2. [Error 2]: Forgetting the diploid nature of the sporophyte and haploid nature of the gametophyte.
   [How to avoid]: Use mnemonics or diagrams to remember the ploidy levels and their relation to meiosis and mitosis.
 **Quick Tips**: The sporophyte is the larger, more visible plant; the gametophyte is reduced and often microscopic.
