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

Explanation

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 adaxial (upper) surface and the abaxial (lower) surface.

2. **Identify the Location of Palisade Tissue**: In a dorsiventral leaf, the palisade tissue is primarily located on the adaxial surface. This tissue consists of tightly packed, elongated cells that are responsible for photosynthesis.

3. **Identify the Location of Phloem**: The phloem is part of the vascular bundles in the leaf. In a dorsiventral leaf, the phloem is located on the abaxial surface. The vascular bundles are arranged such that the phloem is positioned below the xylem.

4. **Summarize the Findings**: Therefore, in a dorsiventral leaf, the palisade tissue is located on the adaxial surface, and the phloem is located on the abaxial surface.

5. **Final Answer**: The answer to the question is: "In a dorsiventral leaf, the location of palisade tissue and phloem is respectively on the adaxial and abaxial surfaces."
