The correct Answer is:
To answer the question regarding which statement is correct for mitosis in most plant members, we will analyze the characteristics of mitosis in plants and compare them with the options provided. ### Step-by-Step Solution: 1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two daughter cells, each having the same number of chromosomes as the parent cell. It is an equational division, meaning the ploidy level remains the same. 2. **Identifying Key Features of Mitosis in Plants**: - In plants, during metaphase, spindle fibers are formed, but they do not have astral rays. - The absence of astral rays in plant cells means they are classified as "anastral." 3. **Defining Terms**: - **Amphiastral**: This term refers to the presence of astral rays, which are found in animal cells, not in plant cells. - **Anastral**: This indicates the absence of astral rays, which is characteristic of plant cells. - **Eumitosis**: This is a type of mitosis where the nuclear membrane dissolves during the process. 4. **Evaluating the Options**: - The first option mentions "amphiastral," which is incorrect for plants since they do not have astral rays. - The second option also mentions "amphiastral," which is again incorrect for the same reason. - The third option states "anastral, acentric, and eumitosis." Here, "anastral" is correct for plants, as they lack astral rays. "Acentric" is also correct as centrioles are not present in plant cells. However, "eumitosis" is a term that can be misleading as it generally refers to the type of mitosis that occurs in both plants and animals. 5. **Conclusion**: The correct answer is the third option, which includes "anastral" and "acentric," as these accurately describe the characteristics of mitosis in most plant members. ### Final Answer: The correct statement regarding mitosis in most plant members is: **Anastral, acentric, and eumitosis.**
