How many egg cell, synergid(s), antipodal cells and polar nulei are present in an embryo sac?

Options

A. 1,3,2,2
B. 1,2,3,2
C. 1,1,2,3
D. 1,3,3,2

Answer

To solve the question regarding the number of egg cells, synergids, antipodal cells, and polar nuclei present in an embryo sac, we can break it down step by step:

### Step 1: Identify the Egg Cell
- The egg cell is the female gamete found in the embryo sac. In flowering plants, there is only **one egg cell** present.

### Step 2: Identify the Synergids
- Synergids are specialized cells that are located adjacent to the egg cell. They play a crucial role in guiding the pollen tube during fertilization. In the embryo sac, there are **two synergid cells**.

### Step 3: Identify the Antipodal Cells
- Antipodal cells are located at the opposite end of the embryo sac from the micropyle. In a typical embryo sac, there are **three antipodal cells** present.

### Step 4: Identify the Polar Nuclei
- Polar nuclei are located in the center of the embryo sac. There are **two polar nuclei** that migrate to the center and can fuse with the male gamete during fertilization.

### Summary of Findings:
- Egg Cells: 1
- Synergids: 2
- Antipodal Cells: 3
- Polar Nuclei: 2

### Final Answer:
In total, the counts are:
- 1 Egg Cell
- 2 Synergids
- 3 Antipodal Cells
- 2 Polar Nuclei
