Eugene drew the following diagram to describe the levels of structural organization of an animal’s body. At the top of the pyramid he put the animal’s body. The level of organization that is least specialized will be at the bottom. Which of the following should Eugene list at the bottom of his diagram?

• organ
• tissue
• cell
• organ system

The diagram shows parts of the human body. These parts work together to help you digest the food you eat. Which term best describes the entire group of parts that are labeled?

•  cell 
• organ
• tissue
• organ system

Kevin is making a class display about different types of tissue. To illustrate one type of tissue, he draws a mail truck moving along a system of roads. His display explains how the truck carries messages from one place to another. Which type of tissue is Kevin most likely comparing to a mail truck carrying messages?

• ground tissue
• muscle tissue 
• nerve tissue
• protective tissue

• organ systems, organisms, atoms, molecules, cells, tissues, organs
• organs, organ systems, organisms, atoms, molecules, cells, tissues

Kayla summarizes the cell theory to her class. She states that all organisms are made up of one or more cells. Which pair of statements correctly completes her summary?

• All cells come from existing cells, and all cells have the same parts
• All cells are the same size, and the cell is the basic unit of all organisms
• The cell is the basic unit of all organisms, and all cells have the same parts
• The cell is the basic unit of all organisms, and all cells come from existing cells. 

One part of the cell theory states that cells come from other cells. Which statement below best explains that this part of cell theory applies to all organisms?

• The cells of all organisms excrete waste.
• The cells of all organisms have cytoplasm
• . The cells of all organisms divide to make more cells.
• The cells of all organisms take in nutrients from their environment

Which of the following correctly pairs a structure in a plant cell with its description?
