Question

The suspensor in a developing dicot embryo plays a critical role in:

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
 **Primary Concept**: Plant Embryology, specifically dicot embryo development.
 **Related Topics**:  Endosperm, nutrient uptake in plants, embryo sac.
 **Prerequisites**: Basic understanding of plant reproduction and embryo development.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the function of the suspensor in a developing dicot embryo.
  We need to identify the critical role it plays.
**Method & Steps**:
 1. Understanding the suspensor's structure and location.
  Reasoning: The suspensor is a stalk-like structure that connects the embryo to the suspensor region of the embryo sac.
 2. Analyzing the options and their relation to the suspensor.
  Working: Option A is incorrect as the suspensor doesn't directly protect against pathogens. Option B is incorrect; hormone synthesis is primarily performed by the embryo itself. Option C is incorrect; the root apical meristem develops from the embryo proper. Option D correctly describes the suspensor's primary function: pushing the embryo into the endosperm for nutrient absorption. 
 3. Concluding the role of the suspensor.
  Result: The suspensor's primary function is to push the embryo into the endosperm and facilitate nutrient absorption. 
  Verification: This aligns with established knowledge of dicot embryo development and the role of the suspensor.
 ## OPTION ANALYSIS
A :x: Protecting the embryo from pathogens and environmental stress is not the primary function of the suspensor. While it might indirectly contribute, it's not the critical role.
B :x:  Synthesizing growth hormones is the role of the embryo itself, not the suspensor.
C :x:  The root apical meristem develops from the embryo, not the suspensor.
D ✓: Pushing the embryo into the endosperm and facilitating nutrient absorption is the primary and critical function of the suspensor in dicot embryo development.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing the suspensor's role with that of the endosperm: The endosperm provides nutrients, but the suspensor facilitates the embryo's access to those nutrients.
  2.Attributing other developmental processes to the suspensor:  The suspensor's role is primarily focused on nutrient transfer.
 **Quick Tips**:
  1.Remember that the suspensor acts as a bridge between the embryo and its nutrient source (endosperm).
  2.Visualize the suspensor as a 'feeding tube' for the developing embryo.
