Station 6—Cellular Reproduction

Page 9 & 10

Directions: Review the Cell Cycle. Complete cut and paste worksheet to help you review the stages of the cell cycle.

Station 1 Interpreting Diagrams

Study the diagram carefully, then answer the questions that follow.

  1. What process is shown in the diagram?

2. Describe what happens during this process.

3. Why is the direction of movement different in the cell to the left than it is in the cell to the right?

4. What would the process in the diagrams be called if the substance being moved was water?

5. What is the difference between endocytosis and exocytosis?

Station 1 Continued…

In the space provided, identify the process involved in moving materials in each of the following cases.

Station 2

Levels of Organization

List the five levels of organization. Define each level and include a sketch.

Station 3

What is the magnification under low power?

How do you carry the microscope?

As you increase ______you see ______of the image.

What do you do to take the blurriness out of the specimen you are looking at?

Station 4 Directions: Read each description and then identify the cell structure. Write your answer on the line provided.

  1. I’m a real “powerhouse.”
That’s plain to see.
I break down food
To release energy.
What am I? ______
  1. I’m strong and stiff
Getting through me is tough.
I’m found only in plants,
But I guess that’s enough.
What am I? ______
  1. My name means “colored bodies,”
And I contain DNA.
I pass on traits to new cells
In a systematic way.
What am I? ______
  1. I’m the “brain” of the cell
Or so they say.
I regulate activities
From day to day.
What am I? ______
  1. Found only in plant cells,
I’m green as can be.
I make food for the plant
Using the sun’s energy.
What am I? ______/
  1. I’m a series of tubes
Found throughout the cell.
I transport proteins
And other things as well.
What am I? ______
  1. I’m full of holes,
Flexible, and thin.
I control what gets out
As well as what comes in.
What am I? ______
  1. Proteins are made here
Even though I’m quite small.
You can find me in the cytoplasm
Or attached to E.R.’s wall.
What am I? ______
  1. I’ve been called a “storage tank”
By those with little taste.
I’m a sac filled with water,
Food, enzymes, or waste.
What am I? ______
  1. Since I contain many enzymes,
I can digest an injured cell;
And can break down a large molecule
Into a smaller one as well.
What am I? ______

1. Name two things found in a plant cell that are not found in an animal cell:

2. How does the shape of a plant cell differ from that of an animal cell?

3. What is the function of the chloroplasts?

4. What is the function of the vacuole?

Station 6 Mitosis Review

Materials: A worksheet with the cell division drawings in a scrambled order and scissors.

Procedure: The drawings are of normal body cells in the process of dividing into two cells. The drawings at this station are not in order;

Cut them out and put them in the space below in thecorrect order to illustrate cell division.

Glue them down when you are sure they are correct.

Label each step of the step on the line next to the letter.

Cell CycleMatching:

______Interphase
______Prophase
______Metaphase
______Anaphase
______Telophase
______Cytokinesis /
  1. The chromosomes are moving to the opposite poles of the cell.
  1. In this phase the nuclear membrane begins to break apart. Chromosomes condense.
  1. The two new cells have been formed.
  1. In this phase the chromosomes line up in the center of the cell.
  1. The stage where everything is copied. The cell is growing in size and in the number of organelles.
  1. The two daughter cells begin to form. Nuclear membrane reforms.

The two new cells that form as a result of mitosis are called what?

If a human body cell, say a skin cell, has 46 chromosomes. After undergoing mitosis, how many chromosomes are in the 2 new skin cells?

The result of meiosis is what kind of cells?

How many chromosomes are in these cells in a human?
