1) Both fungi and animals are heterotrophs although they are markedly different in how they acquire nutrients. Explain. 2) Mycorrhizae are sometimes referred to as "fungus roots." Explain. 3) Give the name of the sexual spore associated with each type of organism, and cite the scientific group name of the fungus. A. Black bread mold B. Cup fungus C. Mushroom 4) What metabolic process do yeast perform that is used in alcohol production? 5) Of what benefit are the mycorrhizae to the plant? 6) Of what benefit is to a typical mushroom if the cap opens up when mature? 7) Explain the composition of lichens and why this composition is usually considered a mutualistic relationship 8) What type of fungus studied is not composed of hyphae as are other fungi? Explain. 9) Why is it advantageous for fungi to reproduce sexually and asexually?

Most yeast fungi which are used in baking belong to which fungal group? chytrids basidiomycetes ascomycetes zygomycetes glomeromycetes If you were studying a plant which had only primary growth and no secondary growth, it would not have any ___. expansion of its root system, vascular tissue differentiation, development of thicker woody branches, or stem elongation. Of the THREE major TISSUE SYSTEMS associated with land plants, which system is responsible for PHOTOSYNTHESIS, STORAGE and SUPPORT in the plant? Ground tissue Vascular tissue Dermal tissue Meristematic tissue Which type of GROUND TISSUE functions in SUPPORT and is ALIVE? supportenchyma sclerenchyma parencyhma collenchyma Once nutrients and water get into a plant root, where do they go? into the xylem into a companion cell into a root hair for storage in to the phloem
