The correct Answer is:
To solve the question regarding the anatomical features of a plant part, we need to analyze each of the given features and determine which type of plant stem they correspond to. Here’s a step-by-step breakdown: ### Step 1: Identify the Hypodermis Composition - **Feature A** states that the hypodermis is made of collenchyma. - In dicot stems, the hypodermis is typically made up of collenchyma cells, which provide support and flexibility. - **Conclusion**: This feature is characteristic of dicot stems. ### Step 2: Analyze the Pericycle Structure - **Feature B** mentions that the pericycle is present in patches of parenchyma and sclerenchyma. - In dicot stems, the pericycle is indeed found as patches rather than a continuous layer, with both parenchyma and sclerenchyma cells present. - **Conclusion**: This feature also corresponds to dicot stems. ### Step 3: Check for the Presence of Bundle Caps - **Feature C** states that a bundle cap is present. - In dicot stems, vascular bundles are often accompanied by a bundle cap, which consists of thickened parenchyma or sclerenchyma cells that cover the vascular bundles. - **Conclusion**: This feature is again indicative of dicot stems. ### Step 4: Determine the Nature of Vascular Bundles - **Feature D** indicates that the vascular bundles are open. - Open vascular bundles contain a vascular cambium, which allows for secondary growth. This is a characteristic of dicot stems, as monocots typically have closed vascular bundles. - **Conclusion**: This feature is also typical of dicot stems. ### Final Conclusion Since all four features (A, B, C, and D) are characteristic of dicot stems, the correct answer to the question is that these anatomical features belong to a dicot stem, specifically an example like the sunflower stem. ### Answer: Option A (All features belong to the dicot stem, e.g., sunflower) ---
