Homework Answers
The correct answer is
(B) microtubules help assemble a cell plate of new plasma membrane between two nuclei
(C) microfilaments help assemble a cell plate of new plasma membrane between two nuclei
The Plants cytokinesis requires dividing the cell to lay down new cell plates to separate the two daughter cells. A structure called phragmoplasts, which supports the assembly of a cell plate is formed from microfilaments, microtubules and some other cellular elements.

Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells? Cytokinesis in plant cells requires formation of a cell plate; cytokinesis in animal cells requires formation of a ring of actin. Cytokinesis in plant cells occurs during G2; cytokinesis in animal cells occurs in the M phase of the cell cycle. Cytokinesis in plant cell results in one large cell with two nuclei; cytokinesis in animal cells results in two cells, each with one...

Question 19 (Mandatory) (2 points) Saved How is plant cell cytokinesis different from animal cell cytokinesis? The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile proteins. Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow. Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase. The structural proteins of plant cells separate the two...
