Q. No.Consider the given two statements:
Statement I:
In animal cells, cytokinesis is achieved by the appearance of a furrow in the plasma membrane.
Statement II:
During cytokinesis in plant cells, the formation of the new cell wall begins with the formation of a simple precursor called the cell plate that represents the middle lamella between the walls of the two adjacent cells.
1. Statement I and Statement II are correct
2. Statement I is correct but Statement II is incorrect
3. Statement I is incorrect but Statement II is correct
4. Statement I and Statement II are incorrect

In plant cell division, the formation of the new cell wall begins with the formation of a simple precursor called:
| 1. | the cell plate that represents the middle lamella |
| 2. | the cell plate that represents the primary cell wall |
| 3. | the cleavage furrow that represents the middle lamella |
| 4. | the contractile ring that represents the primary cell wall |
