The progenitor of the next generation in mature seed is

Options

A. Gamete
B. Spore
C. Oospore
D. Emrbyo

Answer

To solve the question, "The progenitor of the next generation in mature seed is," we will analyze the options provided and understand the reproductive process in plants.

### Step-by-Step Solution:

1. **Understanding the Question**:
- We need to identify what gives rise to the next generation in a mature seed.

2. **Identifying Key Terms**:
- **Progenitor**: This refers to something that gives rise to or produces something else.
- **Mature Seed**: This is the seed that has developed after fertilization and contains the embryo.

3. **Analyzing the Options**:
- **Option A: Gamete**: Gametes are reproductive cells (sperm and egg) that fuse during fertilization. They are not present in the mature seed as progenitors.
- **Option B: Spores**: Spores are a means of reproduction in some plants but are not the progenitor in seeds.
- **Option C: Oospore**: Oospores are formed in certain algae and fungi and are not relevant to seed formation in flowering plants.
- **Option D: Embryo**: The embryo is formed after fertilization when the zygote develops. It is the part of the seed that will grow into the next generation of the plant.

4. **Conclusion**:
- The correct answer is **Option D: Embryo**. The embryo is the progenitor of the next generation in a mature seed.

### Final Answer:
The progenitor of the next generation in mature seed is **embryo**.
