The correct Answer is:
To solve the question "In angiosperms, triple fusion produces," we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Process of Triple Fusion**: - In angiosperms (flowering plants), fertilization involves a unique process known as double fertilization. This process includes the fusion of one sperm cell with the egg cell to form the zygote and the fusion of another sperm cell with two polar nuclei. 2. **Identify the Product of Triple Fusion**: - The fusion of the second sperm cell with the two polar nuclei during double fertilization is referred to as triple fusion. This results in the formation of a triploid nucleus. 3. **Name the Triploid Nucleus**: - The triploid nucleus formed as a result of triple fusion is specifically known as the **primary endosperm nucleus**. This nucleus will eventually develop into the endosperm, which provides nourishment to the developing embryo. 4. **Evaluate the Options**: - Given the options: - A. Polynucleus - B. Secondary Nucleus - C. Gyrotic Nucleus - D. Primary Endosperm Nucleus - The correct answer is **D. Primary Endosperm Nucleus**. ### Final Answer: In angiosperms, triple fusion produces the **Primary Endosperm Nucleus**. ---
