Question

Which of the following features is NOT characteristic of Chlorophyceae?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Characteristics of Chlorophyceae (Green Algae)
 **Related Topics**: Algae classification, Photosynthetic pigments, Cell wall composition
 **Prerequisites**: Basic understanding of algal taxonomy and cell biology
## SOLUTION PATHWAY
**Given Information**:
  The question asks to identify a feature NOT found in Chlorophyceae.
  Options: Presence of chlorophyll a and b, storage of starch, presence of phycobilins, cell wall composed of cellulose.
**Method & Steps**:
 1. Analyze each option's relevance to Chlorophyceae characteristics.
  Reasoning: Chlorophyceae, or green algae, are known for specific features.
 2. Identify the option that does NOT align with these characteristics.
  Working: Let's examine each option:
   a. Presence of chlorophyll a and b: This is a defining characteristic of Chlorophyceae. 
   b. Storage of starch: Chlorophyceae store their food reserves as starch.
   c. Presence of phycobilins: Phycobilins are accessory pigments found in red algae (Rhodophyceae) and cyanobacteria, not typically in Chlorophyceae.
   d. Cell wall composed of cellulose:  The cell walls of Chlorophyceae are primarily composed of cellulose.
 3. Conclude which option is the outlier.
  Result: The presence of phycobilins is NOT a characteristic of Chlorophyceae.
  Verification:  Referencing standard biology textbooks or reliable online resources confirms that phycobilins are absent in green algae.
 ## OPTION ANALYSIS
A ✓: Presence of chlorophyll a and b is a key characteristic of Chlorophyceae.
B :x: Storage of starch is a common feature of Chlorophyceae.
C :x: Presence of phycobilins is incorrect; they are found in red algae and cyanobacteria.
D :x: Cell walls composed of cellulose is a defining feature of Chlorophyceae.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing Chlorophyceae with other algal groups (e.g., Rhodophyceae): Understanding the unique characteristics of each algal group is crucial.
   How to avoid: Use comparative charts or diagrams highlighting the key differences between various algae.
  2.Overlooking the negative phrasing of the question: Carefully read the question to identify what is being asked for (a feature NOT present).
   How to avoid: Underline key words like 'NOT' or 'EXCEPT' to ensure accurate comprehension.
 **Quick Tips**:
  1.Remember the key characteristics of Chlorophyceae: Chlorophyll a and b, starch storage, cellulose cell walls.
  2.Create a mnemonic device to remember the distinguishing features of different algal groups.
