The correct Answer is:
To solve the matching question regarding the parts of dicot roots and their corresponding components, we will analyze each part and match it with the correct description. ### Step-by-Step Solution: 1. **Identify the first part: Epiblema** - The epiblema is the outermost layer of the root, also known as the epidermis. It is responsible for the absorption of water and nutrients. The root hairs that emerge from this layer are unicellular. - **Match:** Epiblema → Unicellular root hair (i) 2. **Identify the second part: Casparian strips** - Casparian strips are found in the endodermis of the root. They are made of a waxy substance called suberin, which helps regulate the flow of water and minerals into the vascular system of the root. - **Match:** Casparian strips → Waxy material suberin (iii) 3. **Identify the third part: Pericycle** - The pericycle is a layer of cells located just inside the endodermis. It consists of thick-walled parenchymatous cells and can give rise to lateral roots. - **Match:** Pericycle → Thick-walled parenchymatous cells (iv) 4. **Identify the fourth part: Stele** - The stele is the central part of the root that contains the vascular bundles (xylem and phloem) and pith. It is responsible for the transport of water and nutrients. - **Match:** Stele → Vascular bundle and pith (ii) ### Final Matches: - A. Epiblema → i. Unicellular root hair - B. Casparian strips → iii. Waxy material suberin - C. Pericycle → iv. Thick-walled parenchymatous cells - D. Stele → ii. Vascular bundle and pith
