(A)____ roots are endogenous in origiin and originates from the cells of (B)_____

Answer

To answer the question:

(A) Lateral roots are endogenous in origin and originate from the cells of (B) pericycle.

### Step-by-Step Solution:

1. **Identify the Type of Roots**: The question asks for a type of root that is endogenous in origin. The term "endogenous" refers to roots that develop from within the plant rather than from the outer layers.

**Hint**: Think about which roots develop from the inner tissues of the plant.

2. **Determine the Origin of the Roots**: The roots that are endogenous in origin are known as lateral roots. These roots emerge from the primary root.

**Hint**: Consider the roots that branch out from the main root.

3. **Identify the Cell Layer**: The question also asks from which cells these roots originate. Lateral roots arise from a specific layer of cells within the root structure.

**Hint**: Recall the layers of cells in the root and identify the one that gives rise to lateral roots.

4. **Name the Specific Layer**: The lateral roots originate from the pericycle, which is a layer of cells located just inside the endodermis of the root.

**Hint**: Think about the layers of the root and which one is responsible for producing new roots.

5. **Final Answer**: Therefore, the complete answer to the question is:
(A) Lateral roots are endogenous in origin and originate from the cells of (B) pericycle.
