Q. 14
Question
The fusing of Golgi vesicles at the metaphase plate of dividing plant cells forms what structure?
a. cell plate
b. actin ring
c. cleavage furrow
d. mitotic spindle
Step-by-Step Solution
VerifiedThe fusing of Golgi vesicles at the metaphase plate of dividing plant cells form a cell plate. The correct option is (a).
The membrane-bound organelle known as the Golgi apparatus is formed by budding procedure. Within this proteins especially glycoproteins, which are basically digestive enzymes are present. It also migrates to the cell's membrane.
The fusing of Golgi vesicles at the metaphase plate of dividing plant cells forms a cell plate which fuses at the metaphase plate after generating a transient structure or phragmoplast and eventually leading to the creation of cell walls that divide the two identical daughter cells and at this time cell plate is formed.
Thus, the correct option is (a).
Actin ring structures are basically ring-like or circular in appearance and are made of actin or myosin motors filaments that, when activated, cause ring constriction. This is developed during the process of cytokinesis. As the Golgi apparatus does not take part in this process, this second option is not correct.
Thus, option (b) is incorrect.
Animal cells undergo cytokinesis, which results in the formation of a constriction by such an actin ring that results in cytoplasmic division. This constriction is known as cleavage furrow. As this is not present in plant cells, the third option is not correct.
Thus, option (c) is incorrect.
Microtubule-based machinery that organizes the movements of chromosomes during mitosis is known as the mitotic spindle apparatus. Their role mainly confines within cell division process especially, they mainly helped in the separation of the duplicated chromosome. So, in the cytokinesis stage, these are disappeared and they have no relation with the Golgi apparatus.
Thus, option (d) is incorrect.
