A seed matures if water content is reduced to ... 'A' .... If the general metablosim ... B .... The embryo enter a state called ... C .... Choose correct option for A, B and C.

Options

A. A - 50-60%, B - fast, C - infertile
B. A - 10-15%, B - slow down, C - dormancy
C. A - 35-50%, B - slow down, C - development
D. A - 35-60%, B - fast, C - Embryogenesis

Answer

To solve the question, we need to fill in the blanks A, B, and C based on the information provided about seed maturation, metabolism, and the state of the embryo.

### Step-by-Step Solution:

1. **Understanding Water Content in Seeds (A)**:
- A seed matures when its water content is significantly reduced. The typical reduction in water content for a mature seed is about 10-15% of its original water content. This reduction is crucial to prevent rotting and to enhance the seed's survivability in the environment.
- **Fill in A**: 10-15%

2. **Metabolism of the Seed (B)**:
- As the seed matures and detaches from the parent plant, it no longer receives nutrients. To conserve energy, the general metabolism of the seed slows down. This slowdown is essential for the seed to survive until it finds a suitable environment for germination.
- **Fill in B**: slows down

3. **State of the Embryo (C)**:
- When the metabolism slows down, the embryo enters a state known as dormancy. Dormancy is a period where the metabolic activities are significantly reduced, allowing the seed to survive adverse conditions until conditions are favorable for germination.
- **Fill in C**: dormancy

### Final Answer:
- A: 10-15%
- B: slows down
- C: dormancy
