Introduction to Fungi - Chapter Summary and Learning Objectives

Fungi are eukaryotic organisms whose cell structures and nutrient sources differentiate them from plants and bacteria. The video lessons included in this chapter can introduce you to the life cycles and environmental effects of fungi types you may already be familiar with, as well as some of those you've never heard of. This chapter can help you understand the following:

  • Characteristics of mushrooms, molds, and yeasts
  • Differences between symbiotic and parasitic fungi
  • Methods of sexual and asexual reproduction
  • Relationship between fungi and environmental health

Video Objective
What are Fungi? - Types and Characteristics Describes characteristics of multicellular and unicellular types of fungi, such as mushrooms and molds.
