Question

Regarding mitosis and cytokinesis, one diffe rence between higher plants and animals is that in plants a. the spindles contain cellulose in addition to microtubules whereas in animals they do not. b. sister chromatids are identical, whereas in animals they differ from one another. c. a cell plate begins to form at telopha se, whereas in animals a cleavage furrow is initiated at that stage. d. chromosomes become attached to the spindle at prohpase, whereas in animals chromosomes do not become attacked until anaphase. e. spindle poles contain centrioles, whereas spindle poles in animals do not

Explanation / Answer

C. a cell plate begins to form at telophase, whereas in animals a cleavage furrow is initiated at that stage.

During cell division of the animal cells, the daughter cells share the cytoplasmic material and get physically separated by a process called cytokinesis. In an animal cell, cytokinesis is carried out by pinching the plasma membrane inward via the contractile ring.

Whereas plant cells have cell wall in addition to plasma membrane, so cytokinesis is not possible in plant cells. As an alternative to this, plant cells develop new cell wall and plasma membrane at the middle of the parent cell.

A series of membrane bound vesicles begins to accumulate and fuse together near to metaphase plate and eventually form a
