The correct Answer is:
To determine the best stage for counting the chromosomes in floral buds of Chrysanthemum, we need to analyze the different stages of the cell cycle and identify which one provides the clearest view of the chromosomes. ### Step-by-Step Solution: 1. **Understand the Cell Cycle Stages**: The cell cycle consists of several stages: Interphase, Prophase, Metaphase, Anaphase, and Telophase. Each stage has distinct characteristics regarding the appearance of chromosomes. 2. **Identify the Key Stage for Counting Chromosomes**: - **Prophase**: During prophase, chromosomes begin to condense and become visible, but they are not yet in their most defined form. Thus, counting chromosomes is difficult. - **Metaphase**: In metaphase, chromosomes are fully condensed and aligned at the cell's equatorial plane. This is the stage where chromosomes have their most distinct morphology, making it easy to count them accurately. - **Anaphase**: In anaphase, chromosomes are being pulled apart towards opposite poles. Counting is not feasible here as they are in the process of separation. - **Interphase**: During interphase, chromosomes are not visible as they are in a relaxed state (chromatin). Therefore, counting chromosomes is impossible. 3. **Conclusion**: The best stage to count the chromosomes in the floral buds of Chrysanthemum is the **Metaphase** stage. This is because, at this stage, chromosomes are clearly visible and well-defined, allowing for accurate counting. 4. **Use of Ideogram**: To represent the counted chromosomes, an ideogram can be used. An ideogram is a diagrammatic representation of chromosomes arranged according to their size, which helps in visualizing and analyzing chromosome numbers. ### Final Answer: The preferred stage to count the chromosomes in floral buds of Chrysanthemum is **Metaphase**. ---
