Cells Working Together

• A tissue is a group of cells that work together to perform a specific function.

• Animals have four basic types of tissues: nerve tissues, muscle tissue, connective tissue, and protective tissue.

• Plants have three types of tissues: transport tissue, protective tissue, and ground tissue.

Chapter 3


Tissues Working Together

• A structure made up of two or more tissues working together to perform a specific function is called an organ.

• The heart, stomach, intestines, brain, and lungs are examples of organs in humans.

• Leaves, stems, and roots are examples of plant organs.

Tissues Working Together, continued

Organs Working Together • A group of organs working together to perform a

particular function is called an organ system. Each organ system has a specific job in the body.

• Examples of organ systems are the digestive system, the respiratory system, and the cardiovascular system.

• Examples of plant organ systems are leaf systems, root systems, and stem systems.

Overview of Organ Systems


Organisms

• Anything that can perform life processes by itself is an organism.

• An organism made of a single cell is a unicellular organism. A unicellular organism must carry out all life processes in order for that cell to survive.

• In contrast, multicellular organisms have specialized cells that depend on each other for the organism to survive.

Chapter 3


Structure and Function

• In organisms, structure and function are related.

• Structure is the arrangement of parts in an organism. Structure refers to the shape and material of a part.

• Function is the job that the part does.

Chapter 3

• The structures of alveoli and blood vessels enable them to perform a function. Together, they bring oxygen into the body and get rid of its carbon dioxide.

For the following questions, write your answers on a separate sheet of paper.

Chapter 3 Standardized Test Preparation

1. Cardiac muscle tissue is only found in the heart. Cardiac muscle tissue contracts to help the heart pump blood throughout the body. The heart is an organ in the cardiovascular system. Describe how this system helps perform maintenance for organisms, such as humans.


1. Cardiac muscle tissue is only found in the heart. Cardiac muscle tissue contracts to help the heart pump blood throughout the body. The heart is an organ in the cardiovascular system. Describe how this system helps perform maintenance for organisms, such as humans.

The cardiovascular system helps maintain the body by providing cells with oxygen and nutrients, and by removing wastes such as carbon dioxide. The cardiovascular system also helps maintain the body by fighting pathogens.



2. Organelles are vital parts of cells that carry out specialized functions. Additionally, the body’s cells combine to form structures that perform specialized functions. Which of the following body structures is made up of similar cells that work together to perform a specific function?

A. organ

B. tissue

C. organism

D. organ system

3. Cells in the body must receive nutrients to perform life processes. Cells must also be able to get rid of their wastes. If wastes could not be removed, they would build up in cells and cause the organism to become sick and die. Which of the following structure help the cell remove wastes?

F. vesicles

G. mitochondria

H. Golgi complex

I. endoplasmic reticulum
