D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: Angiosperm Reproduction
	**Related Topics**: Embryo sac, Fertilization, Double fertilization
	**Prerequisites**: Plant reproductive structures
## SOLUTION PATHWAY
**Given Information**:
	The question asks about the 'filiform apparatus'.
**Method & Steps**:
	1. **Understanding Filiform Apparatus**: The filiform apparatus is a finger-like projection of the wall of synergids that grows towards the micropylar end into the cytoplasm of synergids.
	Reasoning: It plays a crucial role in guiding the pollen tube and releasing its contents into the synergid.
	2. **Location of Filiform Apparatus**: It is located within the synergids of the embryo sac.
	Working:  The embryo sac contains an egg cell, two synergids, three antipodal cells, and a central cell with two polar nuclei.
	Key Point: The filiform apparatus is a characteristic feature specifically of the synergids.
	3. **Identifying the Correct Option**: The option that correctly identifies synergids as having the filiform apparatus is the correct answer.
	Result: Synergids
	Verification: This aligns with the definition and function of the filiform apparatus.
 ## OPTION ANALYSIS
[A] ✓: Synergids - The filiform apparatus is a distinguishing feature of synergids, playing a vital role in pollen tube guidance and fertilization.
[B] :x: Generative cell - The generative cell is part of the pollen grain and divides to form two male gametes; it does not possess a filiform apparatus.
[C] :x: Nucellar embryo - Nucellar embryos are formed from the nucellus tissue and are a form of asexual reproduction; they are not directly related to the filiform apparatus.
[D] :x: Aleurone cell - Aleurone cells are found in the endosperm of seeds and are involved in storing nutrients; they do not have a filiform apparatus.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the parts of the embryo sac: Be clear about the distinct roles of the egg cell, synergids, antipodal cells, and central cell.
		2. Misunderstanding the function of the filiform apparatus: Remember that it guides the pollen tube, not the growth of the embryo.
	**Quick Tips**:
		1. Visualize the embryo sac and the location of synergids and the filiform apparatus.
		2. Associate 'filiform' with 'fingers' to remember the finger-like projections of the apparatus.
