K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Polyembryony
 **Related Topics**: Plant embryology, reproduction in plants
 **Prerequisites**: Basic understanding of plant reproduction and development.
## SOLUTION PATHWAY
**Given Information**:
The question asks to identify the plant species exhibiting polyembryony.
**Method & Steps**:
 1. Understanding Polyembryony:
  Reasoning: Polyembryony is the development of more than one embryo from a single fertilized ovule. This can occur through different mechanisms, including the fertilization of multiple egg cells, the development of nucellar cells (apomixis), or the splitting of a single zygote.
  Formula/Rule: None
 2. Analyzing Options:
  Working: Let's examine each option:
  Mango: Typically develops a single embryo.
  Banana:  Usually develops a single embryo, although variations exist.
  Citrus fruits: Frequently exhibit polyembryony, often due to nucellar embryony (development of embryos from nucellus tissue).
  Papaya: Typically develops a single embryo.
  Key Point:  Citrus fruits are well-known for their high incidence of polyembryony.
 3. Final Step:
  Result: Citrus fruits are the correct answer.
  Verification: The characteristic of polyembryony in citrus fruits is well-documented in botanical literature.
## OPTION ANALYSIS
A :x: Mango does not typically exhibit polyembryony.
B :x: Banana does not typically exhibit polyembryony.
C ✓: Citrus fruits are known for their frequent occurrence of polyembryony.
D :x: Papaya does not typically exhibit polyembryony.
## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing polyembryony with other reproductive phenomena: Students might confuse polyembryony with other plant reproductive mechanisms like apomixis (asexual reproduction) or parthenocarpy (fruit development without fertilization).
  2.Generalizing from limited observations: Students may incorrectly assume that all fruits within a category (e.g., all tropical fruits) exhibit polyembryony.
 **Quick Tips**:
  1.Remember the example of citrus fruits as a classic case of polyembryony.
  2.Focus on the definition of polyembryony – more than one embryo from a single fertilized ovule.
