Cytokinesis
Slide2Cells
Live in a Cycle
,
They Don’t Last Forever.
Cell are the basic unit of structure and function for life.
Once life is established, its existence is on a clock, winding down.
Eventually, all cells meet their demise.There has to be a mechanism to keep cells persisting in nature however.Reproduction is one mechanism.Cell division is the most basic form.
This
is what your next unit is
about,
The Life Of A Cell
.
What a cell does throughout its existence.
AKA the Cell Cycle
Slide3A Cell’s Cycle,
It’s Life
You will learn that a cell does a lot throughout its life.
Makes proteins, duplicates its DNA,
lives
.
Eventually, cells will divide …for specific reasons…that are not random
Division is
highly regulated, cyclical, and has distinct features.
As such, there are five main stages of the cell cycle during a cell’s life that you must know, during each of which specific things happen.
Multicellular Organisms grow by increasing their number of cells, which is accomplished through cell-division. The Hayflick Limit:In 1961, Hayflick and Moore concluded from their research that a cell can only divide somewhere around 50 times before it loses too much genetic information to successfully divide again. This is why humans can’t live forever. Cancer, interestingly enough, overrides this, however.
Slide4The Cell Cycle
These stages of a cell’s life make up what is called the cell cycle.The cell cycle is a repeating sequence of cellular life, growth, and division during the life of a cell.
Your job today is to discover what these five stages are and identify the main process that happens during each of these stages.
Slide5You will create a diagram of a Eukaryotic cell cycle.You will draw the basic cycle, illustrate how a cell looks in each stage (using the handout and book), and give 3 bullet points for each stage in the area either inside or outside your drawing (just make sure everything is on the front of the paper.
Use the handout to guide what to do. Page 125 has basic information but you may need to search further in the book.G1: Protein Synthesis & other life functions:
S: Replication: top of pg198
G2: Chromosome packaging: bottom of pg119
Mitosis: Chapter 6, Section 3
Cytokinesis: Chapter 6, Section 3

Cell Cycle Overview Drawing
You’ll write the bullet points out here.
Slide6Cell Cycle
Cell Cycle Drawing 25pts.
Illustrate the cell cycle on a piece of copy paper.
Use the drawing on page ______ (Cell Cycle) as your basis for your poster. Use the information in the book to help describe the steps.
Label the start of the cycle.
Each Step of the cell cycle must be correctly labeled (1pt)
Each stage must be described. Include at least 3 bullet points describing the step (
1
pts
)
For
Synthesis you must describe the purpose of
replication.
For
Mitosis you must label the goal.
You must draw a picture of the cell in each stage of the cycle (1pt).
At the bottom of the page, answer the following two questions. (5pts)
What is the order of the cell cycle?
The first three stages together are known as what?
Neatness, color, and grammar = 5pts.

You’ll write the 3 bullet points out here or inside the pie
piece for EACH
STAGE.
