Question

Which of the following set of organisms reproduce by fragmentation (asexual mode of reproduction)?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
	**Primary Concept**: Asexual Reproduction by Fragmentation
	**Related Topics**: Types of Asexual Reproduction, Classification of Organisms
	**Prerequisites**: Basic knowledge of different modes of asexual reproduction and common examples of organisms.
## SOLUTION PATHWAY
**Given Information**:
	* Question asks for organisms that reproduce by fragmentation.
	* Fragmentation is a type of asexual reproduction.

**Method & Steps**:
	1. **Define Fragmentation:** Recall that fragmentation involves the breaking of an organism into fragments, each of which can develop into a new individual.
		Reasoning: This is the core concept to differentiate the correct option.
	2. **Evaluate each option:** Examine each option to see if the organisms listed are known to reproduce by fragmentation.
		Working: 
		 A. Amoeba reproduces by binary fission, earthworms by sexual reproduction. Fungi can sometimes fragment but not all. 
		 B. Fungi (some), filamentous algae, and protonema of mosses all reproduce by fragmentation.
		 C. Hydra reproduces by budding, Amoeba by binary fission, bacteria by binary fission
		 D. Earthworm reproduce sexually, bacteria reproduce by binary fission, fungi can sometimes fragment but not all.
	3. **Select the Correct Answer:** Based on the evaluation, option B is the correct answer.
		Result: Option B
		Verification: Double check the reproduction method of each organism listed in the correct option.
 ## OPTION ANALYSIS
[A] :x: Amoeba reproduces by binary fission and earthworms reproduce sexually.
[B] ✓: Fungi (some), filamentous algae, and protonema of mosses all reproduce by fragmentation.
[C] :x: Hydra reproduces by budding, Amoeba by binary fission, bacteria by binary fission.
[D] :x: Earthworm reproduce sexually, bacteria reproduce by binary fission.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. **Confusing Fragmentation with other forms of asexual reproduction:** Remember, fragmentation requires that the parent organism physically breaks into pieces.
		2. **Not knowing how different organisms reproduce:** Memorize the different methods of reproduction for common organisms.
	**Quick Tips**:
		1. Create a table of organisms and their method of reproduction.
		2. Focus on the key characteristics of fragmentation (breaking into pieces) to differentiate it from budding or fission.
