Which of the following statements correctly identifies the difference between plant and animal cells division? 

a.) Both plant and animal cells undergo mitosis and cytokinesis, but they lack the interpase 

b.) plant cells lack centrioles, and they form a cell plate during cytokinesis 

c.) Plant cells lack centomeres, and they form a cell to produce two daughter cells 

d.) The cell walls of the plant prevent the process of cytokinesis

The right answer is (b). In plant cells centrioles are absent, whereas they are present in animal cells. Due to the rigidity of the cell wall, cleavage furrow such develops between animal daughter cells can't be formed. Instead,  a dividing structure known as the  cell plate grows outward from the center of the cell to the parental plasma membrane with which it will fuse forming a new, doubled cell wall between plant daughter cells.

 

Answer (a) is wrong. Both plant and animal cells undergo mitosis and cytokinesis (which is the rght portion of the answer), but 90% percent or more of the cell cycle is spent in interphase. During interphase, cellular organelles double in number, the DNA replicates, and protein synthesis occurs. The chromosomes are not visible and the DNA appears as uncoiled chromatin. so the 2nd part of the answer is wrong.

Answer (c) is wrong. The centomere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids, and plant cells don't lack centromeres.

Answer (d) is wrong. The cell wall of the plant cell doesn't prevent the process of cytokinesis despite its rigidity. The cell plate which is formed in the cytoplasm, grows into a new, doubled cell wall between plant daughter cells.
