In plant cells, cytokinesis is accomplished by the formation of a(n)

Options

A. membrane furrow
B. Equatorial plate
C. Cell plate
D. Spindle

Answer

### Step-by-Step Solution:

1. **Understanding Cytokinesis**: Cytokinesis is the process that occurs at the end of cell division, where the cytoplasm of a parental cell is divided into two daughter cells.

2. **Cytokinesis in Plant Cells**: In plant cells, cytokinesis differs from that in animal cells due to the presence of a rigid cell wall.

3. **Formation of the Cell Plate**: Instead of pinching inwards (as in animal cells), plant cells form a structure known as the cell plate. This process begins with the Golgi bodies, which transport vesicles containing cell wall materials to the center of the dividing cell.

4. **Role of Golgi Bodies**: The Golgi bodies arrange themselves in the middle of the cell and fuse to form the cell plate. This plate grows outward until it fuses with the existing cell wall, effectively dividing the cell into two.

5. **Phragmoplast Formation**: The structure that aids in the formation of the cell plate is called the phragmoplast. It consists of microtubules that help guide the vesicles to the center of the cell.

6. **Completion of Cytokinesis**: As the cell plate expands, it eventually fuses with the plasma membrane and the middle lamella is formed, which is a layer that cements the two daughter cells together.

7. **Conclusion**: Therefore, in plant cells, cytokinesis is accomplished by the formation of a cell plate.

### Final Answer:
In plant cells, cytokinesis is accomplished by the formation of a **cell plate**.
