If a primary root continues to grow. the type of root system will be known as :

Options

A. Secondary
B. Fibrous
C. Tap
D. Stilt

Answer

To solve the question, "If a primary root continues to grow, the type of root system will be known as:", we can follow these steps:

### Step 1: Understand the Types of Root Systems
There are primarily two types of root systems: the tap root system and the fibrous root system.

### Step 2: Identify the Characteristics of Each System
- **Tap Root System**: In this system, the primary root (which develops from the radical) continues to grow and is long-lived. It can be thick and has secondary roots branching off from it. This system is typically found in dicot plants.

- **Fibrous Root System**: In this system, the primary root is short-lived and does not persist. Instead, many thin roots emerge from the base of the stem, creating a dense network. This system is characteristic of monocot plants.

### Step 3: Analyze the Question
The question specifies that the primary root continues to grow. This indicates that the root system in question is likely to be the tap root system, as this system is defined by the persistence and elongation of the primary root.

### Step 4: Conclusion
Given the characteristics of the root systems, if the primary root continues to grow, the type of root system will be known as the **tap root system**.

### Final Answer
The correct answer is **Tap Root System**.
