In which of the following pairs of parts of a flowering plant epidermis is absent

Options

A. Root tip and shoot tip
B. Shoot bud and floral bud
C. Ovule and seed
D. Petiole and pedicel

Explanation

To solve the question about which parts of a flowering plant lack epidermis, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for pairs of parts of a flowering plant where the epidermis is absent.

2. **Identify the Parts of the Plant**: The key parts of a flowering plant include roots, stems, leaves, and their respective tips (root tip and shoot tip).

3. **Define Epidermis**: The epidermis is the outermost layer of cells in a plant, which serves as a protective barrier.

4. **Focus on Growth Regions**: The root tip and shoot tip are regions of active growth in plants. These areas are where cell division occurs rapidly.

5. **Explain the Absence of Epidermis**: In actively growing regions like the root tip and shoot tip, the cells are continuously dividing and do not differentiate into specialized tissues, including the epidermis. Therefore, these regions do not develop an epidermal layer.

6. **Conclusion**: The epidermis is absent in both the root tip and shoot tip of the flowering plant.

### Final Answer:
The epidermis is absent in the root tip and shoot tip of a flowering plant.
