Question

During double fertilization in angiosperms, one sperm fuses with the egg cell, and the other sperm fuses with:

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [C]
## CONCEPT FRAMEWORK
	**Primary Concept**: Double fertilization in angiosperms
	**Related Topics**: Sperm cell function, Angiosperm reproduction, Plant fertilization
	**Prerequisites**: Understanding of plant reproductive structures and processes
## SOLUTION PATHWAY
**Given Information**:
		- In angiosperms, double fertilization involves two sperm cells.
		- One sperm fuses with the egg cell.
		- The question asks about the fate of the second sperm.
**Method & Steps**:
	1.	Identify the role of the first sperm cell.
		Reasoning: The first sperm cell fertilizes the egg cell to form the zygote.
	2.	Determine the target of the second sperm cell.
		Working: The second sperm cell fuses with the central cell (which contains two polar nuclei) to form the triploid endosperm, which nourishes the developing embryo.
		Key Point: Double fertilization results in the formation of both the zygote and the endosperm.
	3.	Conclude the identity of the second fusion.
		Result: The second sperm fuses with the central cell.
		Verification: The central cell is specifically involved in forming the endosperm, confirming the process of double fertilization.
 ## OPTION ANALYSIS
[A] :x: Synergids are not involved in fertilization; they help guide the pollen tube.
[B] :x: Antipodal cells are not involved in fertilization; they have a role in the embryo sac.
[C] ✓: The central cell is indeed the correct answer, as it forms the endosperm.
[D] :x: Integuments develop into seed coats and do not participate in fertilization.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the roles of different cells in the embryo sac: Remember that only the egg and central cell participate in fertilization.
		2. Misunderstanding double fertilization: It involves the fusion of one sperm with the egg and another with the central cell.
	**Quick Tips**:
		1. Recall that double fertilization is unique to angiosperms, making it a key feature to remember.
		2. Use mnemonic devices to remember the roles of synergids, antipodals, and central cell in fertilization.
