The correct Answer is:
To solve the question regarding the characteristics of cells in the quiescent center, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Quiescent Center**: The quiescent center is a region in the root apical meristem that consists of a group of cells that are not actively dividing. This area is crucial for maintaining the root's growth and development. 2. **Identify the Characteristics of Quiescent Cells**: According to the quiescent center theory, the cells in this region are characterized by: - Inactivity (not dividing regularly) - A reduced number of cell organelles - Light cytoplasm - Small nuclei 3. **Analyze the Options**: - **Option (a)**: Dense cytoplasm and prominent nuclei - This is incorrect as quiescent center cells have light cytoplasm and small nuclei. - **Option (b)**: Light cytoplasm and small nuclei - This matches the characteristics of quiescent center cells, making it a potential correct answer. - **Option (c)**: Dividing regularly to add to the corpus - This is incorrect because quiescent center cells are not actively dividing. - **Option (d)**: Dividing regularly to add to tunica - This is also incorrect for the same reason as option (c). 4. **Select the Correct Option**: Based on the analysis, the correct answer is **(b) Light cytoplasm and small nuclei**. ### Final Answer: The cells of the quiescent center are characterized by **(b) Light cytoplasm and small nuclei**. ---
