Amphistomatal condition is observed in the leaves of

Options

A. Dicots
B. Monocots
C. Gymnosperms
D. 1 and 2

Answer

**Step-by-Step Text Solution:**

1. **Understanding Amphistomatal Condition**: The term "amphistomatal" refers to the presence of stomata on both surfaces of a leaf. This means that stomata are found on the upper (adaxial) surface as well as the lower (abaxial) surface of the leaf.

2. **Identifying Leaf Types**: Leaves can be classified into different categories based on their stomatal arrangement. The amphistomatal condition is typically associated with certain types of plants.

3. **Types of Plants**:
- **Monocots**: These are plants that have one seed leaf (cotyledon). Many monocots exhibit amphistomatal conditions, meaning they have stomata on both sides of their leaves.
- **Dicots**: These plants have two seed leaves (cotyledons). Some dicots also show amphistomatal conditions, although it is less common than in monocots.
- **Gymnosperms**: These are non-flowering plants that do not typically exhibit amphistomatal conditions. Their leaves usually have stomata only on one side.

4. **Conclusion**: Based on the above understanding, the amphistomatal condition is primarily observed in the leaves of monocots and, to a lesser extent, in some dicots. Therefore, the correct answer to the question is that amphistomatal conditions are observed in the leaves of both monocots and dicots.

5. **Final Answer**: The amphistomatal condition is observed in the leaves of **monocots and some dicots**.
