Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The embryo sac is polarized. One end points toward the opening of the ovule (Micropylar end) and the other toward the base (Chalazal end).
Step 2: Detailed Explanation:
1. Micropylar End: Contains the "Egg Apparatus." This consists of two synergids and one centrally placed egg cell.
2. Chalazal End: Contains three antipodal cells.
3. Central Region: Contains the large central cell with two polar nuclei.
Step 3: Final Answer:
The synergids and the egg are both located at the micropylar end.
