Biology Word Search
This biology puzzle gathers the big words of the subject: organism, cell, homeostasis and metabolism, the taxonomy ladder from kingdom to genus and species, and the branches of botany and zoology.
The word biology came into use around 1800, and Jean-Baptiste Lamarck in France and Gottfried Treviranus in Germany both used it in 1802 for the study of living things. The naming system is older. Carl Linnaeus sorted plants and animals into ranks in 1735, and by 1758 he was giving every species a two-part Latin name, genus first, so that people are Homo sapiens and the gray wolf is Canis lupus.
Every living thing shares a short list of traits: it is made of cells, takes in energy through metabolism, grows, responds to a stimulus, reproduces and keeps its insides steady, which is homeostasis. A human holds body temperature near 98.6 degrees Fahrenheit by sweating and shivering. In 1977 Carl Woese showed that a group of microbes once lumped with bacteria, the archaea, are a separate branch of life, and biology now sorts all life into three domains.
