The correct Answer is:
To answer the question "Growth is at a _____ level, is principally a consequence of increase in the amount of protoplasm," we need to analyze the options provided and understand the concept of growth in biological terms. ### Step-by-Step Solution: 1. **Understanding Growth**: Growth in biological terms refers to an increase in size or mass of an organism or its parts. It can occur at various levels: cellular, tissue, organ, or organismal. 2. **Identifying Protoplasm**: Protoplasm is the living substance within a cell, which includes the cytoplasm, nucleus, and other organelles. An increase in protoplasm typically indicates an increase in cell size or number. 3. **Evaluating the Options**: - **Tissue Level**: Growth at the tissue level involves an increase in the number of cells, but it does not specifically focus on the increase in protoplasm within individual cells. Therefore, this option is incorrect. - **Organ Level**: Growth at the organ level refers to the development of organs, which is a result of tissue growth, not directly related to the increase in protoplasm within cells. This option is also incorrect. - **Cellular Level**: Growth at the cellular level directly pertains to the increase in the size of individual cells, which is a consequence of the increase in protoplasm. This option is correct. - **Organism Level**: Growth at the organism level refers to the overall growth of the entire organism, which is a result of cellular and tissue growth. However, it does not specifically address the increase in protoplasm. Thus, this option is incorrect. 4. **Conclusion**: The correct answer is that growth is at a **cellular level**, as this level specifically relates to the increase in the amount of protoplasm within cells. ### Final Answer: Growth is at a **cellular** level, is principally a consequence of increase in the amount of protoplasm.
