Cytokinesis in animal cell takes place by __ in __ direction, while in plant cell by __ in __direction-

Options

A. Furrowing, centrifugal, cell plate, centripetal
B. Furrowing, centripetal, cell plate, Centrifugal
C. Cell plate, centrifugal, furrowing, centripetal
D. Cell plate, centripetal, furrowing, centrifugal

Answer

**Step-by-Step Solution:**

1. **Understanding Cytokinesis**: Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell divides into two daughter cells.

2. **Cytokinesis in Animal Cells**: In animal cells, cytokinesis occurs through a process called "furrowing." This involves the inward pinching of the plasma membrane, which creates a cleavage furrow that deepens until the cell is pinched in two.

3. **Direction of Cytokinesis in Animal Cells**: The direction of this furrowing is centripetal, meaning it moves towards the center of the cell.

4. **Cytokinesis in Plant Cells**: In contrast, plant cells undergo cytokinesis by forming a "cell plate." This process involves the fusion of vesicles containing cell wall materials at the center of the cell, which gradually expands outward.

5. **Direction of Cytokinesis in Plant Cells**: The formation of the cell plate occurs in a centrifugal direction, meaning it moves outward from the center towards the cell walls.

6. **Final Answer**: Therefore, the complete statement is: Cytokinesis in animal cells takes place by furrowing in a centripetal direction, while in plant cells it takes place by cell plate formation in a centrifugal direction.
