Question

Why phragmoplasts are not formed during cytokinesis in animal cell ?

Answer 1

This can be understood by studying the difference between mitosis in plants and animals:-
Mitosis is a process of cell division that occurs in both plants and animals. Mitosis results in two daughter cells that are identical to the parent cell. In unicellular organisms, cell division makes new organisms. In the case of multicellular organisms, like plants and animals, mitosis is performed for growth and repair. Mitosis is fundamentally similar in plants and animals, but there are a few key differences.
ifferences occur during the five stages of mitosis. In prophase, the mitotic spindle is formed between the centrioles in animal cells. In plant cells, cortical microtubules form the spindle and the preprophase band forms at the future location of the cell wall. During prometaphase, the band breaks down. During telophase, directly before cytokinesis, the contractile ring forms in animal cells and phragmoplast (cell wall component) forms in plant cells.
