Created by StemPy LabTwo statements about cytokinesis in plant cells are given below. Statement I: In a plant cell, the new wall begins to form in the centre of the cell and grows outward to meet the existing lateral walls. Statement II: The cell plate, the simple precursor of the new wall, represents the middle lamella between the walls of the two adjacent cells.

← Read the following statements about a cell at the end of prophase of mitosis.
(i) The chromosomal material has condensed to form compact mitotic chromosomes.
(ii) Each chromosome is seen to be made of two chromatids attached together at the centromere.
(iii) The centrosome duplicated during interphase, and the two centrosomes have begun to move towards opposite poles of the cell.
(iv) Golgi complexes, endoplasmic reticulum, nucleolus and the nuclear envelope are not seen.
(v) The chromosomes are aligned on the metaphase plate.
(vi) The centromeres have split, and the sister chromatids have separated.
How many of the statements above are correct?Match the stages of mitosis in List-I with their key events in List-II.
List-I (Stage)
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
List-II (Key event)
I. Centromeres split, and the chromatids move to opposite poles
II. A nuclear envelope forms around each cluster of chromosomes, and the nucleolus, Golgi complex and ER reform
III. Spindle fibres attach to the kinetochores, and the chromosomes align at the equator
IV. Chromosomal material condenses, and the centrosomes begin to move to opposite poles →
