Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Plant Reproduction in Angiosperms - Ovule Structure
	**Related Topics**: Megasporogenesis, Embryo Sac Development, Pollination, Fertilization
	**Prerequisites**: Basic understanding of flower structure and plant reproduction.
## SOLUTION PATHWAY
**Given Information**:
	The question asks for the alternative name of the megasporangium within the ovule.
**Method & Steps**:
	1. **Understanding the ovule structure**: The ovule is the structure in the ovary of a flower that develops into a seed after fertilization. It consists of several key parts, including the integuments, funiculus, micropyle, and nucellus.
	2. **Identifying the megasporangium**: The megasporangium is the structure within the ovule that produces the megaspore mother cell (megasporocyte), which undergoes meiosis to produce megaspores. One of these megaspores typically develops into the female gametophyte (embryo sac).
	3. **Nucellus as the megasporangium**: The nucellus is the central part of the ovule and functions as the megasporangium in angiosperms.
	Result: The megasporangium is also known as the nucellus.
## OPTION ANALYSIS
[A] :x: Integument: The integuments are the protective layers that surround the nucellus. They eventually develop into the seed coat.
[B] :x: Funiculus: The funiculus is the stalk that attaches the ovule to the placenta within the ovary.
[C] ✓: Nucellus: The nucellus is the central part of the ovule that houses the megasporangium.
[D] :x: Micropyle: The micropyle is a small opening in the integuments through which the pollen tube enters the ovule during fertilization.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the different parts of the ovule: It's important to clearly understand the distinct roles of the integuments, funiculus, micropyle, and nucellus.
		2. Not recognizing the nucellus as the megasporangium: Remember that the megasporangium is located within the nucellus.
	**Quick Tips**:
		1. Visualize the ovule structure: Draw a diagram of the ovule and label its different parts to reinforce your understanding.
		2. Remember the function of the nucellus:  Associate the nucellus with megaspore formation.
