The correct Answer is:
To answer the question "In dicotyledonous root, all tissues on the inner side of the endodermis constitute," we need to analyze the structure of a dicot root and identify the tissues located within it. ### Step-by-Step Solution: 1. **Understanding the Structure of Dicotyledonous Roots**: - Dicot roots have a specific arrangement of tissues, including the epidermis, cortex, endodermis, pericycle, xylem, and phloem. 2. **Identifying the Endodermis**: - The endodermis is the innermost layer of the cortex in a dicot root. It acts as a selective barrier regulating the flow of water and nutrients into the vascular system. 3. **Tissues Inside the Endodermis**: - The tissues located on the inner side of the endodermis include the pericycle, xylem, and phloem. - The pericycle is a layer of cells that can give rise to lateral roots and is involved in secondary growth. - The xylem is responsible for water and mineral transport, while the phloem transports organic nutrients. 4. **Determining the Correct Answer**: - The question asks for the collective term for all tissues on the inner side of the endodermis. The primary tissues found here are the xylem and phloem, which together form the vascular bundles. - Therefore, the correct answer to the question is "vascular bundles." ### Final Answer: In dicotyledonous roots, all tissues on the inner side of the endodermis constitute the vascular bundles. ---
