Section 3 The Organization of
Living Things
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.

Section 3 The Organization of
Living Things
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.

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.

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.

Section 3 The Organization of
Living Things
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.

Structure and Function, continued
• 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.

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

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.

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
