The correct Answer is:
To solve the question, we need to analyze which of the given organelles is not essential for cells to function properly and divide mitotically. ### Step-by-Step Solution: 1. **Understanding Mitosis**: Mitosis is a type of cell division that occurs in somatic cells, allowing them to replicate and divide. It is crucial for growth, repair, and asexual reproduction in both plant and animal cells. 2. **Evaluating the Options**: - **Option A: Plasma Membrane**: The plasma membrane is essential for all cells, including both plant and animal cells. It regulates what enters and exits the cell. Therefore, this option is not correct. - **Option B: Cytoskeleton**: The cytoskeleton provides structural support and is crucial for cell division, as it helps in the segregation of chromosomes. Thus, this option is also not correct. - **Option C: Mitochondria**: Mitochondria are known as the powerhouse of the cell, generating ATP which is necessary for various cellular processes, including cell division. Therefore, this option is not correct. - **Option D: Plastids**: Plastids, such as chloroplasts, are found only in plant cells and are involved in photosynthesis and storage of products. Animal cells do not have plastids, yet they can still undergo mitosis. 3. **Conclusion**: Since animal cells can divide mitotically without plastids, the correct answer is **Option D: Plastids**. ### Final Answer: **Plastids**
