Oct 31, 2023 · A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.
Oct 19, 2024 · Life: Defining Life. The basic constituents of life are also the most common elements in the universe: carbon, oxygen, hydrogen, nitrogen. Many biochemists therefore regard the emergence of life as inevitable wherever the right chemical and environmental conditions exist.

Biology is a science, but what exactly is science? What does the study of biology share with other scientific disciplines? Science (from the Latin scientia, meaning “knowledge”) can be defined as the process of acquiring knowledge about general truths or the operation of general laws, especially when acquired and tested by the scientific method. It...
Biologists study the living world by posing questions about it and seeking verifiable responses. This approach is common to other sciences as well and is often referred to as the scientific method. The scientific method was used even in ancient times, but it was first documented by England’s Sir Francis Bacon (1561–1626), who set up inductive metho...
Whether scientific research is basic science or applied science, scientists must share their findings in order for other researchers to expand and build upon their discoveries. Collaboration with other scientists—when planning, conducting, and analyzing results—are all important for scientific research. For this reason, important aspects of a scien...

A cell is the smallest and most basic form of life. Robert Hooke, one of the first scientists to use a light microscope, discovered the cell in 1665. In all life forms, including bacteria, plants, animals, and humans, the cell was defined as the most basic structural and functional unit.
Four elements are common to all living things: carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). These four elements alone make up approximately 96% of all living matter. Sulfur (S), phosphorus (P), calcium (Ca), potassium (K), and a few other elements constitute the other 4% of an organism’s mass.
