Bacteria • Single-celled. • Reproduce through Asexual reproduction. • Live everywhere. • Can live in extremely hot and extremely cold temperatures. • Can cause food poisoning, acne, and cavities. • Help waste decompose, make oxygen, and break down food. http://www.lessonplanspage.com/SciencePEBacteriaFriendOrFoeAndProperHandWashing45.htm
Fungi • Mushrooms, rust and yeast are examples of fungi. • Can be uni-cellular or multi-cellular. • Reproduce through sexual reproduction. • Fungi break down dead and organic matter into nutrients to be absorbed by plants. http://tolweb.org/Fungi http://library.thinkquest.org/CR0212089/fungi.htm
