Detailed explanation-1: -The formation of new cell wall begins with the formation of a new simple precursor, called a cell plate that represents the middle lamella between the walls of two adjacent cells. So, the correct answer to the question is Option D i, e, Middle lamella.

Detailed explanation-2: -Chromosomes line up across the middle of the cell. Spindle fibers connect the centromere of each sister chromatid to the poles of the cell.

Detailed explanation-3: -Instead, during telophase, a cell plate forms across the cell in the location of the old metaphase plate separating the two forming cells. During telophase, membrane-enclosed vesicles derived from the Golgi apparatus migrate to the center of the cell where the metaphase plate used to be and fuse to form a cell plate.

Detailed explanation-4: -In the center of the plant cell within its own membrane lies the nucleus. The nucleus is like the command center of the factory. Vital genetic instructions for the cell are found here in the form of DNA. These instructions will be transported and read by organelles known as ribosomes.

Detailed explanation-5: -Answer and Explanation: The phase of mitosis in which chromosomes line up at the middle of the cell is metaphase.
