Question

Identify the INCORRECT statement regarding adventive embryony:

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Adventive embryony
 **Related Topics**: Apomixis, Embryogenesis, Plant reproduction
 **Prerequisites**: Basic understanding of plant reproductive structures (ovule, nucellus, integuments)
## SOLUTION PATHWAY
**Given Information**:
  The question asks to identify the incorrect statement about adventive embryony.
  Options describe different aspects of adventive embryony.
**Method & Steps**:
 1. Analyze each statement regarding adventive embryony.
  Reasoning: Adventive embryony is a form of apomixis where embryos develop from diploid cells of the nucellus or integuments, bypassing the usual sexual reproduction process.  This results in multiple embryos in a single seed.
 2. Evaluate the correctness of each option.
  Working: Option A is correct; embryos do arise from nucellus or integuments. Option B is correct; it's a type of sporophytic apomixis. Option D is correct; it results in multiple embryos. Option C is incorrect because while the embryos are diploid, they are not necessarily genetically identical to the parent plant due to somatic mutations that might have accumulated in the nucellus or integument cells.
 3. Identify the incorrect statement.
  Result: Option C is the incorrect statement.
  Verification: The other options accurately describe aspects of adventive embryony.
 ## OPTION ANALYSIS
A ✓: Correct.  Adventive embryony involves the development of embryos from the nucellus (the nutritive tissue of the ovule) or integuments (the protective layers of the ovule).
B :x: Correct. It's a form of apomixis, specifically sporophytic apomixis, because it involves the development of embryos from diploid sporophytic tissue.
C :x: Incorrect. While the embryos are diploid, they are not always genetically identical to the parent plant. Somatic mutations can occur in the nucellus or integument cells, leading to genetic variation among the embryos.
D :x: Correct.  The development of multiple embryos from the nucellus or integuments is a characteristic feature of adventive embryony.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing adventive embryony with other types of apomixis (e.g., gametophytic apomixis): Understanding the origin of the embryo is crucial in differentiating these types. 
  2.Assuming genetic identity without considering somatic mutations:  Somatic mutations can lead to genetic variation even in asexually produced embryos. 
 **Quick Tips**:
  1.Remember that adventive embryony involves diploid cells, differentiating it from gametophytic apomixis which involves haploid cells.
  2.Focus on the origin of the embryo (nucellus or integuments) to easily identify adventive embryony.
