The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that seed-bearing plants like angiosperms show wide geographic distribution. This means that these plants can be found in various regions around the world. 2. **Identifying the Types of Seed-Bearing Plants**: There are two main types of seed-bearing plants: angiosperms (flowering plants) and gymnosperms (non-flowering plants). Angiosperms are known for their diversity and adaptability. 3. **Diversity of Angiosperms**: Angiosperms are more diverse compared to gymnosperms. This high level of diversity allows angiosperms to adapt to a wide range of terrestrial ecosystems, contributing to their geographic distribution. 4. **Characteristics of Angiosperms**: Angiosperms have seeds that are enclosed in fruits, which can aid in their dispersal. This characteristic is significant for their survival and spread in various environments. 5. **Understanding the Reason**: The reason given is that seeds have better adaptive strategies for dispersal. This is true as seeds can be dispersed by various agents such as wind, water, and animals, allowing them to colonize new habitats. 6. **Connecting Assertion and Reason**: Both the assertion and the reason are true. The ability of seeds to disperse effectively contributes to the wide geographic distribution of angiosperms. 7. **Conclusion**: Since both the assertion and the reason are true, and the reason correctly explains the assertion, the answer is that both statements are correct and the reason is the correct explanation for the assertion. ### Final Answer: Both the assertion and reason are true, and the reason is the correct explanation of the assertion.

Which of the following plants are likely to have wide range of distribution?

Assertion :- Tasmanian wolf and Placental wolf are the good example of convergent evolution. Reason :- More than one adaptive radiation apperared to have occured in an isolated geographical area, (representing different habitats) one can call this convergent evolution.

Assertion : In plants, apomixis is a form of asexual reporduction that minics sexual reproduction. Reason : Apomixis involves the production of seeds without the fusion of gametes.

Assertion : The fungi are widespread in distribution and they even live on inside other plants and animals. Reason : Fungi are able to grow anywhere on land, water or on other organisms because they have a variety of pigments, including chlorophyll, carotenoids, fucoxanthin and phycoerythrin.
