The period of steady state is never reached in the organs of

Options

A. determinate structures
B. indeterminate structure
C. leaves
D. all the above

Answer

To solve the question "The period of steady state is never reached in the organs of," we need to understand the concepts of determinate and indeterminate growth in plants.

### Step-by-Step Solution:

1. **Understanding Growth Patterns**:
- There are two main types of growth in plants: determinate and indeterminate.
- **Determinate Growth**: This type of growth is finite. It means that the growth of the organ stops after reaching a certain size. Examples include flowers and leaves.
- **Indeterminate Growth**: This type of growth is infinite. The organ continues to grow indefinitely without reaching a steady state. Examples include the shoot apical meristem and root apical meristem.

2. **Analyzing the Options**:
- **Option A: Determinate Structures**: These structures reach a steady state as their growth is finite. Therefore, this option is incorrect.
- **Option B: Indeterminate Structures**: These structures do not reach a steady state as their growth is continuous and infinite. This option is correct.
- **Option C: Leaves**: Leaves are considered determinate structures as they stop growing after reaching a certain size. Therefore, this option is incorrect.
- **Option D: All of the Above**: Since both determinate structures and leaves reach a steady state, this option is also incorrect.

3. **Conclusion**:
- The correct answer is **Option B: Indeterminate Structures**. These structures never reach a period of steady state due to their continuous growth.

### Final Answer:
The period of steady state is never reached in the organs of **Indeterminate Structures**.
