Question
Chapter 12, Problem 9TYK
Summary Introduction
Introduction: Cytokinesis is the process by which the cytoplasm of a cell divides to form two daughter cells. Cytokinesis in plant and animal cells differs slightly. The main difference is due to the presence of a cell wall in plants, which is absent in the animals.

What is a main difference between onion root tip (plant cell) mitosis and whitefish blastula (animal cell) mitosis?
A. The DNA is animal cells is inside of a nucleus but there is no nucleus in plant cells.
B. A cleavage furrow is not formed in plant cells due to the rigid cell wall.
C. Plant cells do not have DNA and animal cells do.
D. Plant cells have undergo prophase where they condense their chromosomes but animal cells skip this step.
Which of the following statements correctly identifies the difference between plant and animal cell division?
Select one:
a. The cell walls of plants prevent the process of cytokinesis.
b. Plants cells lack centrioles, and they form a cell plate during cytokinesis.
c. Both plant and animal cells undergo mitosis and cytokinesis, but they lack the interphase.
d. Plant cells lack centromeres, and they form a cell wall to produce two daughter cells.
The drug colchicine prevents the spindles microtubules from forming or growing. What would happen in mitosis to a cell that was given colchicine throughout mitosis?
A. The chromosomes would not condense
B. The nuclear envelope would not dissolve
C. The chromosomes would not line up for metaphase
D. The chromosomes would line up for metaphase but would not pull apart in anaphase.
