The (A)____ venation in (B)____ leaves is reflected in the near similar sizes of vascular bundles (except in main veins) as seen in vertical section of the leaves.

Answer

To solve the question, we need to fill in the blanks with the appropriate terms related to leaf venation and the type of leaves they are found in. Let's break it down step by step:

### Step-by-Step Solution:

1. **Understanding Venation**: The first step is to understand what venation means. Venation refers to the arrangement of veins in a leaf.

2. **Types of Venation**: There are two main types of venation:
- **Parallel Venation**: In this type, the veins run parallel to each other. This is commonly found in monocotyledonous plants (monocots).
- **Reticulate Venation**: In this type, the veins form a network. This is typically found in dicotyledonous plants (dicots).

3. **Analyzing the Question**: The question states that the venation is reflected in the near similar sizes of vascular bundles (except in main veins). This description aligns with parallel venation, where the vascular bundles are of similar size.

4. **Identifying the Type of Leaves**: Since parallel venation is mentioned, we can conclude that it is found in monocot leaves.

5. **Filling in the Blanks**: Based on the above analysis:
- (A) should be "parallel" (for parallel venation).
- (B) should be "monocot" (for monocot leaves).

### Final Answer:
The (A) **parallel** venation in (B) **monocot** leaves is reflected in the near similar sizes of vascular bundles (except in main veins) as seen in vertical section of the leaves.
