The correct Answer is:
To solve the question "The formation of embryo without fusion of gametes is termed as," we need to analyze the options provided and understand the definitions of each term. ### Step-by-Step Solution: 1. **Understanding the Question**: The question asks for a term that describes the formation of an embryo without the fusion of gametes. 2. **Analyzing the Options**: - **Option 1: Apogamy**: This term refers to the development of a haploid sporophyte directly from vegetative cells without the fusion of gametes. This means that an embryo can form without the typical fertilization process. - **Option 2: Apospory**: This term refers to the development of a diploid gametophyte from non-reproductive cells. This does not relate to the formation of an embryo, so it is not the correct answer. - **Option 3: Isogamy**: This term refers to the fusion of similar gametes. Since the question specifies no fusion of gametes, this option is not correct. - **Option 4: Syngamy**: This term refers to the fertilization process, specifically the fusion of male and female gametes. Again, this does not fit the requirement of the question. 3. **Identifying the Correct Answer**: - After analyzing all the options, we find that **apogamy** is the only term that describes the formation of an embryo without the fusion of gametes. Therefore, the correct answer is **apogamy**. ### Final Answer: The formation of an embryo without fusion of gametes is termed as **apogamy**. ---
