Biology Basics

Definition of Biology

• Biology is the scientific study of life and living organisms, encompassing various fields that explore the structure, function, growth, evolution, distribution, and taxonomy of living systems.

Understanding Organisms

• An organism is defined as an individual form of life that possesses one or more cells and is capable of growth and reproduction.
• Organisms can be unicellular (single-celled) or multicellular, ranging from bacteria to humans.

Characteristics of Life

• The arrangement of smaller components into larger components is known as "organization," a fundamental characteristic of life.
• This organization reflects the complex structure of living organisms, which ranges from atoms to molecules, cells, tissues, organs, and systems.

Etymology of 'Biology'

Examples of Organisms

• Organisms can include a wide variety of life forms such as animals, plants, fungi, and microorganisms, each exhibiting unique characteristics and capabilities.
