In a dorsiventral leaf, location of palisade tissue and phloem is respectively on the ______surfaces.

Options

A. adaxial and abaxial
B. adaxial and adaxial
C. abaxial and adaxial
D. abaxial and abaxial

Answer

To answer the question regarding the location of palisade tissue and phloem in a dorsiventral leaf, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of a Dorsiventral Leaf**:
- A dorsiventral leaf has two distinct surfaces: the upper (adaxial) surface and the lower (abaxial) surface.

2. **Identify the Location of Palisade Tissue**:
- The palisade tissue, which is primarily responsible for photosynthesis, is located just below the upper epidermis (adaxial surface) of the leaf. It consists of tightly packed cells that contain a high concentration of chloroplasts.

3. **Identify the Location of Phloem**:
- The phloem, which is responsible for the transport of nutrients and food, is typically located on the abaxial side of the leaf, beneath the lower epidermis.

4. **Conclude the Answer**:
- Therefore, the location of palisade tissue is on the **adaxial surface**, and the location of phloem is on the **abaxial surface**.

### Final Answer:
In a dorsiventral leaf, the location of palisade tissue and phloem is respectively on the **adaxial** and **abaxial** surfaces.
