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

Options

A. Aster
B. Equatorial plate
C. Cell plate
D. Membrane furrow

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 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**: During cytokinesis in plant cells, vesicles from the Golgi apparatus gather at the center of the cell. These vesicles fuse to form a structure known as the cell plate.

4. **Role of the Phragmoplast**: The phragmoplast is a structure that helps in the formation of the cell plate. It consists of microtubules and is crucial for guiding the vesicles to the center of the dividing cell.

5. **Development of the Middle Lamella**: As the cell plate expands, it eventually fuses with the existing cell wall, forming the middle lamella, which is a layer that cements adjacent plant cells together.

6. **Conclusion**: Therefore, in plant cells, cytokinesis is accomplished by the formation of a cell plate, which later develops into the middle lamella.

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