important organisms‚ both in terms of their ecological and economic roles. By breaking down dead organic material‚ they continue the cycle of nutrients through ecosystems. In addition‚ most vascular plants could not grow without the symbiotic fungi‚ or mycorrhizae‚ that inhabit their roots and supply essential nutrients. Other fungi provide numerous drugs such as penicillin and other antibiotics‚ foods like mushrooms‚ truffles and morels‚ and the bubbles in bread‚ champagne‚ and beer. Fungi also cause a

Meghan Veach Bio. 101 Dr. Davis April 28‚ 2014 Chapter 18 - Evolution of Plants and Fungi Plants have been around for over 500 million years‚ the plants all differ so much but they also have many similarities among themselves and also to green algae. Some scholars even think that plants paved the way for land animals by simultaneously increasing the amount of oxygen in the Earth ’s atmosphere and decreasing the amount of carbon dioxide. Evolutionist believe that plants evolved from green

1. How do fungi obtain food? Once obtained‚ how is the method that fungi use to digest food similar to how animals digest food? How is it different? a. Fungi obtain their food by absorption from their surroundings such as soil‚ living and dead plant/animal material. Animals digest food by consuming them and digest them through their digestive systems in their bodies. Fungi on the other hand‚ excrete digestive enzymes onto the food and digest them outside of their system. Then they use hyphae to
