Morphologically different types of spores are produced by

Options

A. Lycopodium and Dryopoteris
B. Lycopodium and salvinia
C. Equisetum and Dryopoteris
D. Selaginella and salvinia

Answer

To answer the question regarding the production of morphologically different types of spores, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Spores**: Spores are reproductive units in plants that can develop into a new individual without fusion with another reproductive unit. They can be classified based on their morphology.

2. **Types of Spores**: There are two main types of spores based on morphology:
- **Homospores**: These are spores that are morphologically similar and do not differentiate between male and female.
- **Heterospores**: These are spores that are morphologically different, producing male spores (microspores) and female spores (megaspores).

3. **Identifying Heterospory**: In plants exhibiting heterospory, two distinct types of spores are produced:
- **Microspores**: These are the male spores.
- **Megaspores**: These are the female spores.

4. **Examples of Plants**:
- **Homosporous Plants**: Examples include Lycopodium and Equisetum, which produce only one type of spore.
- **Heterosporous Plants**: Examples include Selaginella and Salvinia, which produce both microspores and megaspores.

5. **Conclusion**: Therefore, the correct answer to the question is that morphologically different types of spores are produced by heterosporous plants.

### Final Answer:
Morphologically different types of spores are produced by heterosporous plants.
