Question

Which one of the following statements regarding post-fertilization development in flowering plants is incorrect?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Post-fertilization development in flowering plants
	**Related Topics**: Double fertilization, embryogenesis, endosperm development, fruit development
	**Prerequisites**: Basic understanding of plant reproduction and floral anatomy.
## SOLUTION PATHWAY
**Given Information**:
	Four statements regarding post-fertilization development in flowering plants.
	We need to identify the incorrect statement.
**Method & Steps**:
	1. Analyze each statement individually in the context of post-fertilization development.
		Reasoning: Post-fertilization events include the development of the embryo, endosperm, and fruit from the fertilized structures.
		Formula/Rule:  No specific formulas are needed. This is a conceptual question.
	2. Evaluate the correctness of each statement based on botanical knowledge.
		Working:
			Statement A: Ovary develops into fruit - This is correct. The ovary wall develops into the pericarp (fruit wall).
			Statement B: Zygote develops into embryo - This is correct. The zygote undergoes mitosis to form the embryo.
			Statement C: Central cell develops into endosperm - This is correct. Double fertilization results in the formation of the endosperm from the central cell.
			Statement D: Ovules develop into embryo sac - This is incorrect. The ovule contains the embryo sac (megagametophyte), but the ovule itself develops into the seed after fertilization.
	3. Identify the incorrect statement.
		Result: Statement D is incorrect.
		Verification: The ovule is a structure within the ovary that contains the female gametophyte (embryo sac).  After fertilization, the ovule develops into the seed, not the embryo sac.
## OPTION ANALYSIS
A ✓: Ovary develops into fruit - Correct. The ovary wall matures to form the fruit wall (pericarp).
B :x: Zygote develops into embryo - Correct. The zygote is the fertilized egg that divides to form the embryo.
C :x: Central cell develops into endosperm - Correct. The central cell of the embryo sac is fertilized to form the endosperm.
D :x: Ovules develop into embryo sac - Incorrect. The ovule contains the embryo sac; the ovule develops into the seed.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the ovule with the embryo sac: Remember the ovule is the structure containing the embryo sac.
		2. Misunderstanding the products of double fertilization:  Understand that double fertilization results in both a zygote (2n) and a primary endosperm nucleus (3n).
	**Quick Tips**:
		1. Visualize the process using diagrams of flower anatomy and post-fertilization development.
		2. Remember the key terms: zygote, embryo, endosperm, ovule, seed, ovary, fruit.
