The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Apospory**: Apospory refers to a specific reproductive process in certain plants where the gametophyte is formed directly from the sporophyte without undergoing meiosis. 2. **Typical Plant Reproduction**: In the typical life cycle of plants, the sporophyte (2N) undergoes meiosis to produce spores (N), which then develop into gametophytes (N). This is the standard process of alternation of generations. 3. **Apospory Process**: In apospory, this meiosis step is skipped. Instead, the sporophyte directly produces a gametophyte. This means that the gametophyte retains the diploid (2N) condition of the sporophyte. 4. **Examples of Apospory**: Apospory is commonly observed in certain groups of plants, notably ferns and mosses. In these plants, the direct formation of gametophytes from sporophytes occurs without the typical reduction division. 5. **Conclusion**: Therefore, the answer to the question "Apospory is direct formation of" is that it is the direct formation of a gametophyte from a sporophyte. ### Final Answer: Apospory is the direct formation of a gametophyte from a sporophyte. ---
