The correct Answer is:
To solve the question "Primary roots and its branches constitute," we need to identify the type of root system that is formed by primary roots and their branches. Here’s a step-by-step breakdown of the solution: ### Step 1: Understand the Components - **Primary Roots**: This is the main root that develops from the radical of the seed. - **Branches**: These are the lateral roots that grow from the primary root. ### Step 2: Identify Root Systems There are different types of root systems in plants: 1. **Adventitious Root System**: Roots that arise from parts of the plant other than the root. 2. **Tap Root System**: A single main root (the primary root) that grows deeper into the soil, with smaller lateral roots branching off. 3. **Fibrous Root System**: A network of many thin roots that spread out from the base of the plant. 4. **Seminal Roots**: These are roots that originate from the seed. ### Step 3: Analyze the Options - The question asks which type of root system is constituted by primary roots and their branches. - The tap root system is characterized by a prominent primary root with branches, which fits the description given. ### Step 4: Conclusion Based on the analysis, the primary roots and their branches constitute a **Tap Root System**. Therefore, the correct answer is **Option 2: Tap Root System**. ### Final Answer The primary roots and their branches constitute a **Tap Root System**. ---
