Question

Cell plate formation during karyokinesis takes place due to the action of
(a) Lysosomes and endoplasmic reticulum
(b) Lysosomes and mesosomes
(c) Golgi body and endoplasmic reticulum
(d) Mesosomes and mitochondria

Answer 1

Hint: Organelles of the cells that contain ribosomes that help in the synthesis of proteins which are used for the cell plate formation during cytokinesis of mitotic division in plants.

Complete answer:
During the interphase of mitosis, the cell synthesizes proteins with the help of ribosomes in the Golgi apparatus and the endoplasmic reticulum prepares the cell for the mitosis phase. During the metaphase of the mitosis phase, the metaphase plate or equatorial plate is formed. The Golgi apparatus and endoplasmic reticulum release synthesized proteins into this plate and when the cell, as soon as it enters the telophase it undergoes karyokinesis and cytokinesis. In cytokinesis, with the help of these proteins, it forms a cell plate that separates the cell into two daughter cells.

Additional Information: - In mitosis, the cell not only separates the nucleus by karyokinesis, but the cell itself is divided into two daughter cells by a separate process called cytokinesis.
- In plant cells, wall formation starts in the center of the cell and grows outward to meet the existing lateral walls. The formation of a new cell begins with the formation of a cell plate.
So, the correct answer is ‘Golgi body and endoplasmic reticulum’

Note: -In animal cells, cytokinesis is achieved by the appearance of a furrow in the plasma membrane. The furrow gradually deepens and ultimately joins in the center dividing the cytoplasm into two
Between the walls of two adjacent cells, the cell plate represents the middle lamella.
-At the time of cytoplasmic division, organelles like mitochondria and plastids get distributed between the two cells.
