The Study of Life
Living things are made of one or more cells.
Cells are the basic unit of structure and function in all living things.

![Page 9: Click on a lesson name to select. Chapter 1 The Study of Life Section 1: Introduction to Biology Section 2: The Nature of Science Section 3: Methods](https://reader036.vdocuments.site/reader036/viewer/2022062619/5519403855034679738b4580/html5/thumbnails/9.jpg)
Specialized cells are organized into groups that work together called tissues.
Displays Organization
The Study of Life
Living things also display organization, which means they are arranged in an orderly way.
Tissues are organized into organs.
Organ systems work together to support an organism.

Responds to Stimuli
The Study of Life
Anything that is part of the internal or external environments and causes some sort of reaction by the organism is called a stimulus.
The reaction to a stimulus is a response.

Requires Energy
The Study of Life
Living things get their energy from food.
Most plants and some unicellular organisms use light energy from the Sun to make their own food and fuel their activities.
Organisms that cannot make their own food get energy by consuming other organisms.

Maintains Homeostasis
The Study of Life
Regulation of an organism’s internal conditions to maintain life is called homeostasis.
If anything happens within or to an organism that affects its normal state, processes to restore the normal state begin.

What is science?
Science is a body of knowledge based on the study of nature.
The nature, or essential characteristics, of science is scientific inquiry.
The Study of Life
Scientific inquiry is both a creative process and a process rooted in unbiased observations and experimentation.
