10.1 Cell Growth, Division,
and Reproduction
Lesson Objectives
Explain the problems that growth causes for cells.
Compare asexual and sexual reproduction.
BUILD Vocabulary
A. The chart below shows key terms from the lesson with their definitions. Complete the chart by
writing a strategy to help you remember the meaning of each term. One has been done for
you.
How I’m Going to Remember
the Meaning
Term
Definition
Asexual
reproduction
A cell divides into two new
daughter cells
Cell division
Reproduction involving only one
parent organism
Sexual
reproduction
Reproduction in which cells from
two different parents join to form
a new organism
Division, divides, and daughter all begin
with D. A cell divides into daughter cells.
B. As you work through this lesson, you may find these terms in the activities. When you write a
key term or a definition, highlight the term or the definition.
BUILD Connections
Growing Pains An analogy takes two things that seem to be different and shows how they
can be similar.
1. How does the analogy of a cell to a town help you understand
why cells divide?
2. Find a partner. Using the analogy, explain to your partner why
cells are small.

T-Chart A T-chart is a way to organize information. One way to make a T-chart is to write the
textbook headings in the left column of the chart. Rewrite these headings as questions in the right
column. Then, as you read, answer the question in your own words.
As you read the lesson, complete the T-chart.

Venn Diagram A Venn diagram is made up of overlapping circles. It is a useful tool for
comparing two or even three topics. In each circle, write one of the topics that you want to
compare. In the space where the circles overlap, write the features that the topics share. In the
space where the circles do not overlap, write the features that are unique to each topic.
Complete the Venn diagram below to compare asexual and sexual reproduction.

Ratio of Surface Area to Volume
1. Draw a line from the edge of Circle A
to the dot in the center of Circle A. Do
the same with Circle B. Which line
looks longer?
2. Look at the triangles in each circle.
Suppose they have to move to the dot in
the center. (Assume the triangles are
traveling at the same speed.) Which
triangles would get to the center
faster—those in Circle A or those in
Circle B?
Explain your reasoning.
3. Imagine that Circle A and Circle B are cells. The triangles are materials the cells need to
move in or out, or exchange. Which cell would have a greater problem exchanging materials?
Explain your reasoning.

Pet Shop Accident Some plants and animals can reproduce by cell division.
In the space below, draw a picture of how a plant might produce a new plant this way.
