Cytokinesis in an animal cell takes place by ___ method in ____ direction; while in a plant cell it occurs by _______method in ___ direction.

Options

A. (a) furrowing, centrifugal, cell plate, centripetal
B. (b) furrowing, centripetal, cell plate, centrifugal
C. (c) cell plate, centrifugal, furrowing, centripetal
D. (d) cell plate, centripetal, furrowing, centrifugal

Answer

To answer the question regarding cytokinesis in animal and plant cells, we can break down the information as follows:

### Step-by-Step Solution:

1. **Understanding Cytokinesis**:
- Cytokinesis is the process during cell division where the cytoplasm of a parent cell divides, resulting in the formation of two daughter cells.

2. **Cytokinesis in Animal Cells**:
- In animal cells, cytokinesis occurs by the **furrowing method**.
- This involves the formation of a groove or furrow in the plasma membrane, which deepens until the cell is pinched into two separate daughter cells.
- The direction of this process is **centripetal**, meaning it occurs from the outer edges of the cell towards the center.

3. **Cytokinesis in Plant Cells**:
- In plant cells, cytokinesis occurs by the **cell plate formation method**.
- This process begins with the formation of a cell plate at the center of the dividing cell, which gradually extends outward to form a new cell wall between the two daughter cells.
- The direction of this process is **centrifugal**, meaning it starts at the center and extends outward towards the periphery of the cell.

4. **Final Statement**:
- Therefore, the complete answer to the question is:
- Cytokinesis in an animal cell takes place by **furrowing method** in **centripetal direction**; while in a plant cell, it occurs by **cell plate method** in **centrifugal direction**.

### Final Answer:
Cytokinesis in an animal cell takes place by **furrowing method** in **centripetal direction**; while in a plant cell, it occurs by **cell plate method** in **centrifugal direction**.
