Life. What is more fascinating? Humans are one of millions of species on Earth—there are so many we haven’t found them all. Biology is a journey to explore the five kingdoms: monera, protista, fungi, plantae, and animalia, and the roles they play in human lives. It will be a long journey; along the way we’ll meet life forms large and small. We’ll find out about bacteria, cyanobacteria, protozoans, fungus species, and myriad plants and animals. What are the origins of life? What are its limits? Scientists have discovered life in Antarctic ice, in the deep oceans, at hydrothermal vents, in the atmosphere, and in countless places we thought lifeless. Now we wait for word of life on other planets. For the basics and the latest news, read Biology at Suite 101. Enjoy the journey!
