Seeds are required for fruit growth

Options

A. Throughout
B. Early phase
C. Late phase
D. Mid phase

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks during which phase of fruit growth seeds are required. We need to analyze the role of seeds in fruit development.

2. **Identifying the Structure**: The seeds are formed from the ovules located in the ovary of the flower's female reproductive part, known as the gynoecium. The gynoecium consists of three parts: stigma, style, and ovary.

3. **Fertilization Process**: The seeds are formed through fertilization, which involves the union of the male gamete (pollen) with the female gamete (ovule). This process leads to the formation of a triploid structure called endosperm, which is essential for nourishment.

4. **Role of Endosperm**: The endosperm, formed during fertilization, serves as a nutritive tissue that provides food for the developing embryo within the seed. It is crucial for the growth of the embryo.

5. **Phases of Fruit Growth**: After fertilization, the ovary develops into a fruit, and the ovules develop into seeds. During the early phase of fruit growth, the endosperm is present and provides nourishment to the developing fruit.

6. **Conclusion**: Therefore, seeds are required for fruit growth primarily during the early phase, as they provide the necessary nutrients for the embryo's development and the overall growth of the fruit.

### Final Answer:
Seeds are required for fruit growth during the **early phase**.
