Cleidoic egg is an adaptation for

Options

A. Aquatic life
B. Marine life
C. Terrestrial life
D. Aerial life

Answer

**Step-by-Step Solution:**

1. **Understanding Cleidoic Eggs**: Cleidoic eggs are a type of egg that has a protective shell and several membranes, including the amnion. These features are important for the development of the embryo.

2. **Identifying the Environment**: Cleidoic eggs are primarily laid by reptiles and birds. These organisms are adapted to live on land (terrestrial environment) rather than in water.

3. **Function of the Shell**: The tough outer shell of the cleidoic egg serves to protect the developing embryo from external environmental factors. One of the key functions is to prevent desiccation (drying out) and dehydration.

4. **Adaptation to Terrestrial Life**: Since cleidoic eggs are designed to protect the embryo in a terrestrial environment, they allow the organisms that lay them to reproduce away from water bodies. This adaptation is crucial for survival in habitats where water may not be readily available.

5. **Conclusion**: Therefore, cleidoic eggs are an adaptation for terrestrial life, allowing reptiles and birds to reproduce successfully in a variety of environments.

**Final Answer**: Cleidoic eggs are an adaptation for terrestrial life.
