Question

Phragmoplast is precursor of
A. Leucoplast
B. Chloroplast
C. Chromoplast
D. Cell plate

Answer 1

Hint: During the late cytokinesis cell specific structure obtained known as the phragmoplasts. The observation of the phragmoplasts only with the help of zygnematophyceae, embryophyta and phragmoplast phyta. It is obtained from the microfilaments, microtubules and the endoplasmic reticulum.

Complete answer:
Two new daughter cells are formed when organelles are divided, and newly generated cells are identical and return to the interphase process occurring during the cytokinesis in which the division of the cytoplasm takes place. Plants cells cannot form furrows as found in the animals due to the rigid cell wall. In the telophase cell plates across in the location of the previous metaphase. And in the telophase membrane enclosed vesicles obtained from the Golgi bodies and migrate into the metaphase.
With its own plasma membrane the growing cell plate fuses in the existing plasma membrane and obtains the two daughter cells. The cell division and maintenance of the plant form with the help of cell wall. Phragmoplasts that carry vesicles of cell wall material to the new cell plate process occurred by the microtubules spindle structure that is present in the plants.

Therefore the correct option is (D).

Note: Cell plate formation occurs in the terrestrial plants by the process cytokinesis, and delivered endosomal vesicles that help to carry cell membrane components and cell wall to the cell division and Golgi bodies. And the development of the cell wall between the two groups of the chromosomes that present in the midpoint of the dividing cells of the plant.
