Lesson 2: Cell Structure and Function

Identify the animal cell.

• 
• 
• 
• 

Identify the plant cell.

• 
• 
• 
• 

Analyze the animal cell diagram. What is the job of the cell membrane?

• The cell membrane protects the cell and controls the movement of substances into and out of the cell.

• The cell membrane gives shape and structure support .

• The cell membrane gives light energy to make food.

Analyze the cell diagrams. What is function of the nucleus?

• The nucleus is the factory that makes proteins.

• The nucleus stores water in the cells.

• The nucleus controls all cell activity. The nucleus is like the control center.

Analyze the plant cell. What is the function of the central vacuole?

• The central vacuole helps to gives shape to the cell.

• The central vacuole stores food, water, and waste material.

• The central vacuole does not have an important job.

Compare the animal cell to the plant cell. What makes the animal cell different from the plant cell? Select two answers.

• The animal cell does not contain chloroplasts and the plant cell does contain chloroplasts.

• The animal cell does not have a cell membrane and the plant cell does have a cell membrane.

• The animal cell does not have a cell wall and the plant cell does have a cell wall.

• Both cells have the same organelles.

What is the function of the mitochondria?

• The mitochondria is the control center for the cell.

• The mitochondria gives plants their green color.

• The mitochondria powers the cell through chemical reaction. It processes food for the cell.

Identify the cell.

• elodea plant cell

• human cheek cell

• neuron cell

• red blood cells

Identify the cell.

• red blood cell.

• human cheek cell

• elodea plant cell

• xylem cell

Analyze the plant cell. What is the function of the chloroplasts?

• Chloroplasts uses light energy to make food for the plant.

• Chloroplasts control the cell.

• Chloroplasts store water and waste for the cell.
