A lichen is a two-member symbiotic community consisting of a fungus, which provides structure and some protection, and a photosynthetic algae. There has been a great deal of debate as to whether this relationship is beneficial to the algae, or whether they would grow faster if they were not trapped within the fungal matrix. How would we describe a lichen if it were: a) beneficial to the alga b) provided no benefit to the alga c) slowed the growth of the alga (The fungus definitely benefits from access to fixed carbon.)

Which of these statements are false for lichens? Please select all correct answers. a.) Fungal species are obligate symbionts b.) A lichen is two species engaged in commensalism c.) Algal species are facultative symbionts d.) Lichen fungi gain sugars from algae e.) The relationship is beneficial for both fungi and algae
Lichen-forming fungi are generally capable of reproducing by the production of ascospores: single-celled reproductive units small enough to be carried away on the air. What questions does this fact pose about the obligate / facultative nature of this mutualism?
. Fungi with hyphae ________. A) acquire their nutrients by phagocytosis B) are called yeasts C) have cell walls that consist mainly of cellulose microfibrils D) are adapted for rapid directional growth to new food sources E) reproduce asexually by a process known as budding
Fungi can reproduce in all of the following manners except __________.a) mitosisb) by axsexual sporesc) by sexual sporesd) by binary fissione) vegetatively
Many fungal infections of humans are considered to be opportunistic, meaning that fungi that are normally free-living (usually in soil) can sometimes survive, and even thrive, on or inside the human body. From the fungal “point of view,” what unique challenges would be encountered when trying to survive on human skin? What about inside human lungs?
2) Provide two examples of how fungi are beneficial and two examples of how fungi are detrimental to humans Beneficial: a) b) Detrimental: a) b)
1) Lichens are often early colonizers, growing on bare rock and in areas where there are no plants yet. How can lichens survive in such habitats, where there is seemingly no nutrients and harsh physical conditions? 2) Distinguish between a hypha (hyphae) and a mycelium. Give an example of a species you observed each in today.
Examine the image of a lichen (“Lichen Thallus”) and identify the symbiotic algal cells among the hyphae (Fig. 8.6.).
While working in a plant disease diagnostic lab, you receive a sample of a very dead tomato plant. The plant has rotted roots and the symptoms match known fungal and oomycete diseases of tomatoes. Explain one difference between true fungi and oomycetes that you could observe to determine what type of organism is killing the tomatoes?
A) Describe the life cycle of a moss, indicating the characteristics by which it differs from that of a fern. B) Describe the major characteristics of Archaea.

The main product of fossil fuel combustion is CO2 , and thisis the source of the increase in atmospheric CO2 concentration. Scientistshave proposed strategically situating containers of these algae near industrialplants or near highly congested city streets. Considering the process ofphotosynthesis, how does this arrangement make sense?
