Substance synthesised during growth are

Options

A. Protoplasmic
B. Apoplasmic
C. Protoplasmic and apoplasmic
D. Nucleic acids

Answer

To answer the question "Substance synthesized during growth are," we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Understanding Growth**:
- Growth refers to a permanent and irreversible increase in the size, weight, and volume of an organism. It involves the synthesis of various substances.

2. **Types of Substances Synthesized**:
- During growth, two main types of substances are synthesized:
- **Protoplasmic Substances**: These are the living components of the cell, including proteins, lipids, carbohydrates, and nucleic acids.
- **Non-Protoplasmic (Apoplasmic) Substances**: These include substances that are not part of the living cell, such as cell wall components and storage materials.

3. **Identifying the Correct Substances**:
- The question provides options for substances synthesized during growth. We need to identify which of these substances fall under the categories mentioned above.
- The first option refers to protoplasmic substances, which are indeed synthesized during growth.
- The second option refers to apoplasmic substances, which are also synthesized during growth.
- The third option combines both protoplasmic and apoplasmic substances, which is correct as both types are synthesized during growth.
- The fourth option mentions nucleic acids, which are a type of protoplasmic substance and are synthesized during growth.

4. **Conclusion**:
- Based on the analysis, the correct answer is that both protoplasmic and apoplasmic substances are synthesized during growth. Therefore, the correct option is the one that includes both types of substances.

### Final Answer:
The substances synthesized during growth are both protoplasmic and apoplasmic substances.
