Question

In some organisms, karyokinesis is not followed by cytokinesis as a result of which, multinucleate condition arises leading to the formation of syncytium. The perfect example for this is

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
	**Primary Concept**: Cell division and its variations
	**Related Topics**: Karyokinesis, Cytokinesis, Syncytium formation, Endosperm development
	**Prerequisites**: Basic understanding of cell division (mitosis), plant embryology
## SOLUTION PATHWAY
**Given Information**:
	* Karyokinesis not followed by cytokinesis leads to multinucleate condition (syncytium).
	* Need to identify an example of syncytium formation.
**Method & Steps**:
	1. Understand the terms: Karyokinesis is nuclear division, cytokinesis is cytoplasmic division, and syncytium is a multinucleated cell.
		Reasoning: Definition of terms
	2. Analyze the options:
		A. Appearance of a furrow in cell membrane: This is a process of cytokinesis, which is the opposite of what the question asks.
		B. Liquid endosperm in coconut: This is a classic example of syncytium formation due to repeated karyokinesis without cytokinesis.
		C. Sexual reproduction: This involves fusion of gametes, not syncytium formation directly.
		D. Fertilization: This is the process of gamete fusion, not related to syncytium.
	3. Identify the correct option:
		Result: Option B is the correct answer as liquid endosperm in coconut is a syncytium.
 ## OPTION ANALYSIS
[A] :x: Furrow formation is part of cytokinesis, not syncytium formation.
[B] ✓: Liquid endosperm in coconut is formed by repeated karyokinesis without cytokinesis, resulting in a syncytium.
[C] :x: Sexual reproduction is a broader process and not directly related to syncytium formation.
[D] :x: Fertilization is a separate process, not syncytium formation.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing karyokinesis and cytokinesis: Understanding that karyokinesis is nuclear division, and cytokinesis is cytoplasmic division is important.
		2. Not recognizing syncytium examples: Remembering that liquid endosperm is a syncytium will help to answer the question easily
	**Quick Tips**:
		1. Think of examples you have encountered in biology
		2. Focus on the key word - syncytium
