Choose the incorrect one with respect to cytokinesis in plants

Options

A. In plants cells, wall formation starts in the centre of the cell and grows outward to meet the existing lateral walls
B. The formation of the new cell wall begins with the formation of a simple precursor, called cell plate
C. The cell plate represents the middle lamellum between the walls of two adjacent cells
D. The cytokinesis in a plant cell is achieved by the appearance of a furrow in the plasma membrane called the cell cleavage

Answer

To solve the question regarding cytokinesis in plants, we will analyze each statement provided and determine which one is incorrect.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** "In plant cells, wall formation starts in the center of the cell and grows outward to meet the existing lateral walls."
- **Analysis:** This statement is correct. In plant cells, during cytokinesis, a cell plate forms at the center and expands outward until it fuses with the existing cell walls.

2. **Analyze the Second Statement:**
- **Statement:** "The formation of new cell wall begins with the formation of the simple precursor called cell plate."
- **Analysis:** This statement is also correct. The cell plate is indeed the precursor to the new cell wall in plant cells, and it forms during cytokinesis.

3. **Analyze the Third Statement:**
- **Statement:** "Cell plate represents the middle lamellum between the walls of the two adjacent cells."
- **Analysis:** This statement is correct as well. The cell plate eventually develops into the middle lamella, which is the layer between the walls of two adjacent plant cells.

4. **Analyze the Fourth Statement:**
- **Statement:** "The cytokinesis in the plant cell is achieved by the appearance of the furrow in the plasma membrane called the cell cleavage."
- **Analysis:** This statement is incorrect. In plant cells, cytokinesis does not occur through the formation of a cleavage furrow (which is characteristic of animal cells). Instead, it occurs through the formation of a cell plate.

### Conclusion:
The incorrect statement regarding cytokinesis in plants is the fourth statement: "The cytokinesis in the plant cell is achieved by the appearance of the furrow in the plasma membrane called the cell cleavage."
