The distribution of mitochondria and plastid between the daughter cells during cytokinesis -

Options

A. Is random
B. Is directed by centrioles
C. Is directed by mitotic spindle
D. Is directed by nuclear membrane

Answer

### Step-by-Step Text Solution:

1. **Understanding Cytokinesis**: Cytokinesis is the process that occurs at the end of cell division (mitosis or meiosis) where the cytoplasm of a parental cell is divided into two daughter cells. This is crucial for the equal distribution of organelles, including mitochondria and plastids.

2. **Role of Mitochondria and Plastids**: Mitochondria are known as the powerhouse of the cell, responsible for energy production, while plastids (such as chloroplasts in plants) are involved in photosynthesis and storage of products. Both organelles are vital for the functioning of the daughter cells.

3. **Distribution Mechanism**: During cytokinesis, the distribution of organelles like mitochondria and plastids does not follow a strict pattern. Instead, it occurs randomly. This means that as the cell divides, the organelles are distributed in a way that is not controlled or predetermined.

4. **Conclusion**: Therefore, the distribution of mitochondria and plastids between the daughter cells during cytokinesis is characterized as random. This ensures that both daughter cells receive a sufficient number of these essential organelles to function properly.

5. **Final Answer**: The correct answer is that the distribution of mitochondria and plastids between the daughter cells during cytokinesis is random.
