In angiosperms since two types of fusions, syngamy and triple fusion take place in ________the phenomenon is termed double fertilisation.

Options

A. embryosac
B. ovary
C. ovule
D. seed

Answer

To answer the question regarding where double fertilization occurs in angiosperms, we can follow these steps:

### Step 1: Understand the Concept of Double Fertilization
Double fertilization is a unique process in angiosperms where two types of fusions occur: syngamy and triple fusion. Syngamy involves the fusion of one male gamete with the egg cell, while triple fusion involves the fusion of the other male gamete with two polar nuclei.

### Step 2: Identify the Location of Double Fertilization
Double fertilization takes place within the female reproductive structure of flowering plants. Specifically, it occurs in the embryo sac, which is located inside the ovule.

### Step 3: Clarify Related Structures
- **Ovary**: The part of the flower that contains the ovules.
- **Ovule**: The structure within the ovary that contains the embryo sac.
- **Embryo Sac**: The specific location within the ovule where double fertilization occurs.

### Step 4: Determine the Most Specific Answer
While double fertilization involves the ovule and the ovary, the most specific answer to the question is the embryo sac, as this is the exact site where both syngamy and triple fusion occur.

### Conclusion
The answer to the question is: **embryo sac**.
