Question

What is the main function of gemmae in some Bryopsida?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
 **Primary Concept**: Bryophyte Reproduction
 **Related Topics**: Bryopsida, asexual reproduction, vegetative propagation
 **Prerequisites**: Basic understanding of plant reproduction and bryophyte life cycle.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the main function of gemmae in Bryopsida (a class of mosses).
  Options are provided: sexual reproduction, water absorption, photosynthesis, and vegetative reproduction.
**Method & Steps**:
 1. Understand Gemmae:
  Reasoning: Gemmae are small, multicellular structures found in some liverworts and mosses (Bryopsida). They are involved in asexual reproduction.
  Formula/Rule: N/A
 2. Analyze the function:
  Working: Gemmae are detached from the parent plant and can develop into new individuals. This is a form of asexual reproduction called vegetative reproduction.
  Key Point: Gemmae are not directly involved in sexual reproduction, water absorption, or photosynthesis.  Their primary role is to produce new plants asexually.
 3. Identify the correct option:
  Result: Vegetative reproduction is the main function of gemmae.
  Verification:  The definition of gemmae aligns with vegetative reproduction.
 ## OPTION ANALYSIS
A :x: Sexual reproduction is a process that involves the fusion of gametes, which gemmae are not directly involved in.
B :x: Water absorption is the primary function of rhizoids in bryophytes, not gemmae.
C :x: Photosynthesis is the process by which plants produce food, but gemmae's primary role isn't dedicated to photosynthesis. They can perform photosynthesis, but their main function is reproduction.
D ✓: Vegetative reproduction is the correct answer as gemmae are involved in the asexual propagation of the plant.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing gemmae with spores: Spores are involved in sexual reproduction, while gemmae are involved in asexual reproduction.
  How to avoid: Understand the difference between sexual and asexual reproduction in plants and the role of different structures involved.
  2.Confusing the function of gemmae with that of rhizoids: Rhizoids are structures for water absorption.
  How to avoid: Clearly understand the function of each structure in bryophytes.
 **Quick Tips**:
  1.Remember that gemmae are involved in asexual reproduction.
  2.Associate gemmae with vegetative propagation in bryophytes.
