Introduction to Biology Are you interested in learning more about living things, or perhaps beginning to train for a career in the healthcare or medical professions? Bacteria, archaea, protists, and many fungi have only one cell and are able to survive and reproduce in a huge array of ways that puts plants and animals to shame. Evolution by natural selection is the process that has led to the great diversity of species on Earth. Welcome! The study of biology incorporates everything imaginable related to the life on Earth. Viruses are an unusual group because they are unable to reproduce without the use of a host cell.

However, with most of the characteristics listed below we can think of one or more examples that would seem to break the rule, with something nonliving being classified as living or something living classified as nonliving. Prior to the 1600's many people believed that nonliving things could spontaneously turn into living things. Biology is the study of life. 150,875 already enrolled!

Class site for introductory biology. For example, an ecologist, who looks at how organisms interact with each other and the environment, might specialize in marine ecology, population ecology, plant ecology or freshwater ecology. These include movement, respiration, sensitivity, growth, reproduction, the release of wastes and the consumption of food. Biology is brought to you with support from the Our mission is to provide a free, world-class education to anyone, anywhere. Genes are the basic units for passing traits from parent to offspring. An Introduction to Basic Biology is a course that covers information for a general high school or level one university biology course. Biology also includes the study of evolutionary relationships among organisms and the diversity of life on Earth. Many have been around for hundreds of years, whilst others are far newer and are often developing very rapidly. This unit is part of the Biology library.

However, everyone has to start somewhere and studying biology can enlighten your understanding of the world around you. In ad… The DNA of a cell holds all the information that a cell needs to keep itself alive. They contain all the information required to keep an organism alive. The process of natural selection has been sculpting life for over 4 billion years and is the cornerstone of modern biology. Fields of study such as evolution, ecology, and genetics are themselves very broad topics and contain many specializations within each field. A confirmation email has been sent to the email address that you just provided. There is a huge array of sub-disciplines or branches of biology; all up more than 60.

Although our knowledge of the world around us is constantly changing, there are a few basic principles of biology that should hopefully remain useful for many years to come. ‘Life’ is the title given to separate the things that are able to function by themselves from material objects such as rocks and water. Fundamental principles of biochemistry, genetics, molecular biology, and cell biology. Various characteristics describe most living things. When organisms reproduce, the information from genes is passed from parent to offspring. The genes that are passed from parent to offspring then provide the information to cells to keep the new organism alive.

Eukaryotic cells are found in more advanced organisms such as animals, plants, and fungi. Other higher-level organisms include plants and fungi. Biological function at the molecular level is particularly emphasized and covers the structure and regulation of genes, as well as, the structure and synthesis of proteins, how these molecules are integrated into cells, and how these cells are integrated into multicellular systems and organisms. Life is a phenomenon existing (as far as we know) only on Earth. This is one of over 2,200 courses on OCW.
