B. Embryo
C. Endosperm
D. Fruit

Answer

To answer the question "Which one of the following structure is known as the progenitor of the next generation?", we need to identify the structure that gives rise to the next generation in plants.

### Step-by-Step Solution:

1. **Understanding Progenitor**: The term "progenitor" refers to something that gives rise to or produces another entity. In the context of biology, especially in plant reproduction, we are looking for the structure that leads to the formation of the next generation.

2. **Identifying the Relevant Structures**: In flowering plants, the reproductive structures include the male part (stamen) and the female part (gynoecium). The female part consists of carpels, which include the ovary, style, and stigma.

3. **Focus on the Ovary**: The ovary is the part of the flower that contains ovules. Each ovule has the potential to develop into a seed after fertilization.

4. **Embryo Development**: Within each ovule, there is a structure called the nucellus, which contains the embryo sac. The embryo sac is the female gametophyte and contains the egg cell, which is the female gamete.

5. **Fertilization Process**: After fertilization occurs, the fertilized egg will develop into an embryo. This embryo is crucial as it will grow into a new plant.

6. **Final Structure**: The embryo, once developed, is contained within the seed. When the seed germinates, the embryo will grow into a new plant, thus serving as the progenitor of the next generation.

7. **Conclusion**: Therefore, the correct answer to the question is that the **embryo** is known as the progenitor of the next generation in plants.

### Answer:
The structure known as the progenitor of the next generation is the **embryo**.
