Question

Which of the following features is NOT characteristic of slime molds during their plasmodial stage?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Slime mold life cycle and characteristics of the plasmodial stage.
 **Related Topics**: Protists, eukaryotic organisms, nutrition in protists.
 **Prerequisites**: Basic understanding of cell biology, including cell walls, nuclei, and nutrition.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the characteristics of slime molds in their plasmodial stage.
  Options describe different features: multinucleate cytoplasm, presence of cell walls, phagotrophic nutrition, and formation of a network of veins.
**Method & Steps**:
 1. Understand the plasmodial stage of slime molds.
  Reasoning: The plasmodial stage is characterized by a multinucleate mass of cytoplasm called a plasmodium. This plasmodium lacks cell walls and moves as a large, amoeboid mass.
 2. Analyze each option.
  Working: 
       * **Multinucleate cytoplasm:** The plasmodium is multinucleate, so this is a characteristic.
       * **Presence of cell walls:** Plasmodia lack cell walls. This is the key difference.
       * **Phagotrophic nutrition:** Slime molds in the plasmodial stage engulf food particles, so this is characteristic.
       * **Formation of a network of veins:** The plasmodium often forms a network of veins for efficient nutrient transport.
 3. Identify the feature NOT characteristic of the plasmodial stage.
  Result: The presence of cell walls is not a characteristic of the plasmodial stage.
  Verification:  The plasmodium is a large, multinucleate mass of cytoplasm without individual cell walls.
 ## OPTION ANALYSIS
A ✓: Multinucleate cytoplasm – This is a characteristic of the plasmodial stage. The plasmodium is a single mass of cytoplasm with many nuclei.
B :x: Presence of cell walls – Plasmodia lack cell walls. This is the correct answer.
C :x: Phagotrophic nutrition – Slime molds in the plasmodial stage engulf food particles, so this is characteristic.
D :x: Formation of a network of veins – The plasmodium often forms a network of veins for efficient nutrient transport.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing the plasmodial stage with other stages of the slime mold life cycle:  Remember the key characteristics of the plasmodial stage, especially the lack of cell walls.
  2. Misunderstanding phagotrophic nutrition:  Phagotrophic means engulfing food particles, a common method of nutrition for slime molds in the plasmodial stage.
 **Quick Tips**:
  1.Focus on the defining features of the plasmodial stage: multinucleate, amoeboid, lacks cell walls.
  2. Visualize the plasmodium as a large, flowing mass of cytoplasm.
