Question

The process of formation of haploid spores from a diploid sporophyte is called:

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Meiosis
 **Related Topics**: Sporophyte, Gametophyte, Alternation of Generations, Spore Formation
 **Prerequisites**: Understanding of diploid and haploid cells, the cell cycle, and meiosis.
## SOLUTION PATHWAY
**Given Information**:
The question describes the formation of haploid spores from a diploid sporophyte.
**Method & Steps**:
1. Identify the type of cell division involved.
  Reasoning:  The process involves reducing the chromosome number from diploid (2n) to haploid (n).
  Formula/Rule: Meiosis is the type of cell division that reduces the chromosome number by half.
2. Determine the correct term for this process.
  Working: Meiosis is the process that produces haploid spores from a diploid sporophyte in plants.
  Key Point: Mitosis produces genetically identical diploid cells, while fertilization combines haploid gametes to form a diploid zygote. Pollination is the transfer of pollen, not the formation of spores.
3. Select the correct option.
  Result: Meiosis is the correct answer.
  Verification: The definition of meiosis aligns perfectly with the question's description.
## OPTION ANALYSIS
A :x: Mitosis is a type of cell division that produces two identical daughter cells, both diploid. It does not reduce the chromosome number.
B ✓: Meiosis is a type of cell division that reduces the chromosome number by half, producing haploid cells (spores in this case) from a diploid parent cell (sporophyte).
C :x: Fertilization is the fusion of gametes (haploid cells) to form a zygote (diploid cell). It is the opposite of spore formation.
D :x: Pollination is the transfer of pollen grains from the anther to the stigma in flowering plants. It's a prerequisite for fertilization but not directly involved in spore formation.
## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing mitosis and meiosis: Remember that mitosis maintains the chromosome number, while meiosis reduces it.
  2.Misunderstanding the roles of fertilization and pollination: These processes are involved in sexual reproduction but not directly in spore formation.
 **Quick Tips**:
  1.  Remember that meiosis is a reductional division.
  2. Relate the terms diploid (2n) and haploid (n) to the process.
