Most resistant stage in the life cycle of angiosperms is its:

Options

A. Embryo stage
B. Seed stage
C. Flowering stage
D. Fruiting stage

Answer

To solve the question regarding the most resistant stage in the life cycle of angiosperms, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Life Cycle of Angiosperms**:
- Angiosperms, or flowering plants, go through several stages in their life cycle, including germination, growth, flowering, and seed production.

2. **Identify the Stages Listed in the Options**:
- The options given are:
- A) Embryo stage
- B) Seed stage
- C) Flowering stage
- D) Fruiting stage

3. **Evaluate Each Stage**:
- **Embryo Stage**: This is the early stage of development within the seed, but it is not the most resistant stage as it is still developing.
- **Seed Stage**: The seed is the mature ovule that contains the embryo and is surrounded by a protective seed coat. It is known for its ability to withstand harsh conditions.
- **Flowering Stage**: This stage is when the plant produces flowers for reproduction, but it is not resistant to environmental stresses.
- **Fruiting Stage**: This stage involves the development of fruits from fertilized flowers, but like the flowering stage, it is not as resistant as seeds.

4. **Conclusion**:
- The seed stage is the most resistant stage in the life cycle of angiosperms. Seeds can remain dormant for long periods and can withstand extreme environmental conditions due to their reduced metabolic activity and protective structures.

### Final Answer:
The most resistant stage in the life cycle of angiosperms is the **Seed Stage**.
